Got Some Time to Kill? Three Productive Things to Do During Your Free Time

Do you often find yourself wasting your free time? Despite how many hours we spend at work or in school, there will always be those hours when we haven’t got much to do. In the social media age, the norm would be to mindlessly scroll on either Facebook, Instagram, or Twitter until you have something to do.

Doing this has more cons than pros since scrolling through your feed never really did any good for anyone, especially for your own mental health. Not to mention, your precious free time could be used for more valuable activities – ones that serve a purpose. If you want to spend your time more wisely while still having fun, then read on!

Take Online Courses

The perfect way to spend your free time would be to consume more knowledge. Once we get out of school and proceed with our respective jobs, we often forget the value of learning without the academic pressure. The good thing is that it’s never too late to learn anything new.

Try learning a new language, for example. Thanks to the digital age, there is an abundance of language-learning apps and websites you can visit and some are even free! If you want to pick up a new hobby or learn more technical skills, there are a ton of institutions that offer extensive online education courses to help you add to your skills arsenal.

Declutter Your Space

If you often find that your mind is a chaotic mess, then chances are that your living space is too. Most of the time, we are too busy to even assess our surroundings to determine whether or not our space has turned into a pigsty. However, it’s important to keep our space neat and tidy for a number of reasons. Things will be easier to find, it’ll be a good space to come home to, and on top of all of that, you won’t be afraid to have guests come over.

Decluttering gives you the opportunity to get rid of things you no longer need. This is especially important for those who have accumulated clutter (like documents) over the years. Decluttering your space also gives you a chance to declutter your mind while passing the time by doing something productive.

Try Podcasts

If you’ve always listened to music to pass the time, whether it’s at home or during your commute, then you should try to switch things up for a change. Listening to music when you’re on the go can be entertaining, and even therapeutic for many. However, you might want to try listening to podcasts.

Podcasts are like talk shows minus the visual factor. They can range from a few minutes to a few hours. In podcasts, people talk about a specific thing or sometimes, just have random conversations about anything, really. Podcasts are a good way to keep yourself entertained while absorbing information at the same time. Just put on a podcast while you’re doing housework, the time will fly by quickly!

Having free time doesn’t mean that you have to be unproductive. Although rest is very important, there are a number of ways to spend downtime without having to resort to mindlessly scrolling through social media. Being productive during our free time is important for our mental wellness and overall self-development.

Collection! 10 must-have skills to improve conversions with Google Ads in 2019

Novice veterans should look at it.

The core of using Google ads to boost sales is testing and optimization. Whether you are a novice seller or an experienced advertiser, you should take some of the Google marketing techniques you need to try in your own optimization strategy. But what should be done to turn Google advertising into a money-making machine? Take a look at these 10 simple and fast Google ad usage tips.

1. Optimize negative keywords

Negative keywords are one of the most powerful elements of Google’s advertising campaigns. Although often overlooked by novice advertisers, it does ensure that you exclude searchers who are not related to the product and the niche market. There are three benefits to using negative keywords:

• Keep your ROI (return on investment) because they prevent you from burning money on keywords that don’t get a good return.

• Make sure that searchers only see ads related to the content they are searching for.

• Increase the likelihood of more targeted traffic, thereby increasing the potential for conversion.

Based on the above three points, negative keywords can be said to be the first optimization step you should take to improve the performance of your campaign or ad group. In order to drive sales through Google ads, you need to review whether negative keywords have been added to under-targeted campaigns or ad groups, including those with low clickthrough rates (CTR), low or no high-cost ads. .

How to find negative keywords?

If you want to find possible negative keywords for your advertising campaign, you can refer to the following three methods:

• As shown below, you can use Google’s auto-fill feature to find out if keywords and products are relevant.

Use Google to search for keywords you are using or want to test to see who is using these keywords to advertise and what natural search results have appeared. As shown below, you might think that “glasses” is a good search term for your home products, but it is also more likely to bring you a lot of people looking for glasses, so it’s for you. The click rate has a negative impact.

Use keyword research tools such as SEMrush or Kparser.

2, check and update the keyword match type

Keyword matching can tell Google about the relevance of a search term to your ad, and thus properly display your ad. Therefore, your Google ads should include a variety of campaigns that use different match types to suit the goals or strategies of each campaign.

Over time, the keyword matching strategy will change as you improve and segment the performing advertising campaigns. For example, when launching a new campaign, you might want to start with a broad match. This will help you reach more audiences when collecting valuable ad data to complete initial optimization. You can then switch to a combined or exact match type to maintain a high degree of relevance to your campaigns, increasing your conversion opportunities. This means that your campaigns will be narrower and more subdivided, although its impressions will decrease, but the targeting will increase, so it will give you a higher conversion rate.

Think of it as starting a larger net at the beginning and then improving your advertising campaign by narrowing it down to a more subdivided search match. Switching to broad match will give you more control over all types of traffic, helping you boost your sales with Google ads.

In short, your ultimate goal should be to have your campaigns consist of ad groups with fewer keywords and use different match types to reach a narrower, broader audience. You can use the data provided by the latter for more specific keywords, searchers, and more precise matches.

3. Expand your budget with long tail keywords

Another way to ensure that your campaigns receive more targeted traffic conversions is to test and add long tail keywords. Long tail keywords mean less competition and higher conversion opportunities, even if they are considered “unwelcome”, they can increase sales while reducing CPC costs. In the content analysis platform Ahrefs’s study of 1.9 billion keywords, they found that 29% of the keywords of 10,000 searchers per month contained three or more words.

(keyword length vs monthly search volume)

You can find long tail keywords through Google’s auto-complete feature, Ahrefs or other keyword research tools. However, you also need to look at the current natural traffic data to find long tail keywords that you might not have considered when accessing your product.

You can also use another method, which is to use a keyword research website like Answer the Public to find the questions people are asking. Understanding the “problem” content is a sensible way to make long tail keywords a advantage.

4. Review and delete duplicate keywords

When you add a list of Google campaigns while optimizing and adding keywords, even experienced advertisers often forget to remove duplicate keywords.

Why is it important to keep a focus on keywords and remove duplicate keywords? Because they affect your Quality Score, you also consume a budget that you don’t have to spend. If you bid on the same keyword more than once and submit it to the “auction” process each time, you are actually competing with yourself and adding unnecessary CPC costs.

Of course, there are times when you need to bid for duplicate keywords, in the following cases:

• The same keywords that will be used for different ad placements, search and display ads.

• Use different match types for repeated keywords.

• Segmented ads serving different ad slots, at which point you can bid for the same keyword in each campaign that serves different locations.

So how do you find and remove duplicate keywords? Below is a quick guide to using Google.

Find keywords

(1) Register your Google advertising account at;

(2) Click on all campaigns in the left navigation bar;

(3) Click on the Keywords tab in your account to view all keywords.

Find duplicate keywords

(1) Click Keyword to sort keywords in alphabetical order;

(2) Click on the March type to sort the keywords according to the matching type;

(3) If you want to search for more specific keywords, enter your keywords in the blank text box above the keyword performance graph, then click Search, your keywords will be displayed in the list below.

5. Review the relevance of landing pages

Simply put, ensuring the relevance of the landing page will lead to better Quality Scores, which will ensure you pay a lower cost, but it has a bigger and more complex impact. If your budget gets a good CPC-related metric, but your conversion rate is stagnant, you’ll need to check your URLs to make sure they’re relevant to your ads, search, and target audience.

Here are the specific steps to review the relevance of your landing page:

step 1

As shown in the image below, check the relevance of keywords or landing pages in Google Ad Activity metrics. Your Quality Score and landing page experience are a worthwhile indicator.

Step 2

Make sure you have a user-friendly and well-architected URL page. Don’t use too many links to bomb your potential shoppers.

Step 3

To find the “winning formula” that belongs to you, you need to test various CTA (call to action) buttons and titles. This is especially important when the searcher goes to a product category, promotion, or content page.

Step 4

Test the speed of your site to make sure your landing page doesn’t load too slowly.

6, using RLSA (search advertising remarketing) to invigorate advertising

What should be done for advertising campaigns with small thunder and heavy rain? Suspending these ads may miss some possible sales. Instead, you can use RLSA to combine and test these ad groups. Some old ads may be outdated or unable to attract new traffic, but that doesn’t mean they won’t win in remarketing campaigns. As we all know, RLSA is extremely important to advertisers’ sales channels. It will attract traffic that is already familiar with your brand back to your website, thus increasing the chances of conversion.

7. Bidding for your brand name and competitor’s brand name

If you don’t bid for your brand name, your competitors will do it. In addition, this approach can help you get to the top of the SERP (Search Results Page) page, knowing that your store doesn’t usually appear organically on the first page of brand name search results.

At the same time, it may be profitable to start a bid against a competitor’s brand name, as this will help you use the products you offer to attract their customers. However, this is also a practice that needs to be balanced. You need to make sure your ads don’t mimic competitors and offer a choice they didn’t think of. However, be aware that you cannot use any brand name in the ad text or landing page URL, and you also need to adopt certain strategies. Here are some tips you need to know at the beginning:

Selectively choose competitors. You should target competitors whose target audience is very close, not the big brands that people know and trust.

Develop a corresponding budget strategy. Brand keywords, especially those that are competitive, will result in higher CPA (cost per operation). If you are a new brand with a new budget, maybe you can stick to the bid until you build your business.

8, using the Location Bid Adjustments (positioning bid adjustment) function

The adjustment of Location Bid and geographic goals is not just for traditional brick-and-mortar stores. Adjusting your advertising campaigns based on geographic location can have a big impact on your advertising performance. For example, geographic location helps you sell seasonal products or products that are suitable for different climates. By looking at Google ad metrics, you can see which locations are driving better ad performance. You can then create more campaigns for searchers who live in these locations, or pause locations where conversions aren’t implemented. By getting geolocation and user location reports, you can quickly analyze this information.

Adding Location Bid Adjustments to your campaign will ensure that you can automatically adjust the frequency of your ads based on geographic regions, cities, and countries. The location extension feature will allow you to set different bids for potential shoppers in key locations.

9. Use Ad Extensions while maintaining relevance

Enabling ad extensions in your account, campaign, or ad group can bring you more clicks. With sitelink, callout and review extensions, and structured snippets, you can improve the overall user experience of your ads while highlighting promotions, products, or valuable brand information. To increase sales. In order to take advantage of this, you need to make sure that:

• Create extensions at the account level.

• Use extensions as much as possible – as long as they are relevant.

• Synchronize snippet extensions and ad elements.

• Use the ad rotations feature to select a combination of well-behaved extensions.

10. Use various indicators for SEO optimization

The focus of the last optimization tip is your indicator. The effectiveness of your Google ads can help you point the way to the right SEO optimization. The success of all kinds of advertising campaigns, their keywords and their location will bring you a lot of data about drainage. And as we know, building a strong strategy that combines SEO and PPC advertising is the foundation of an online store’s success.

If you don’t have a good optimization strategy as a support, you are probably just playing a money-burning game. If you want to get out of the stagnation of sales, then use these 10 tips from now on!


Six issues to be aware of before a newcomer uses Google SEO

How do I turn Google SEO into store traffic? How to set the internal and external chain?

Traffic, as one of the important sources of store orders, carries the efforts of the sellers. As we all know, Amazon CPC advertising and Google has become the main way for many sellers to get traffic. In the two major traffic channels of Google AdWords and Google SEO, the free Google SEO has become the preferred choice for most sellers.

However, how to convert it into the flow of the store, how to set the internal and external chain, etc. has become a problem that plagues the seller. To this end, Zeng Dewei, a special tutor of the Google Foreign Trade School with 9 years of experience in Google website sharing, shared his experience. We know that Google mainly has two channels of traffic, one is the Google AdWords Google auction system, and the other is Google SEO Google free natural ranking traffic. What is the difference between the two, and where are the advantages?

Zeng Dewei: Google AdWords Google Auctions has recently changed its name to Google Ads. Google Ads traffic is paid traffic, advertisers use the Google Ads advertising system to set keywords to do bidding ads, or advertise through the network, remarketing features.

The advantage of Google Ads is that advertisers can quickly get a lot of traffic through the advertising system. It can accurately target the target market, freely open and close the ad delivery, control the delivery cost, and the ad delivery time can be accurate to every hour. Accurate to a city or business district. However, the keyword auction advertising cost of Google Ads is relatively high, the advertising cost of the network is relatively low, and the remarketing function can improve the advertising conversion rate.

The biggest advantage of Google SEO is that it is free, and the traffic customers who come in through the Google SEO keyword natural rankings have high conversion rate and are relatively stable. Since the Google SEO algorithm update in September 2016, the Google SEO free traffic database is basically globally updated within a week. This update is very important, it breaks the shortcomings that used to be Google SEO for 3 months, or even half a year, one year! In addition, you can also get a large number of customers for a long time, and the brand effect is good! What are the factors that affect Google SEO’s access to traffic?

Zeng Dewei: Google SEO looking for traffic, first of all to do a website that complies with Google SEO rules. There are a lot of website companies and station-building programs in China, and there are not a lot of Google SEO implementation cases. Basically, there is no practical effect on paper, so the website that is made does not receive Google SEO traffic. And often these factors are the most overlooked in Google SEO operations.

Then, the factors that affect Google SEO’s access to traffic include: First, the factors of the website. Whether the website is self-developed, whether there is a deep transformation of the website for Google SEO, continuous improvement through foreign third-party testing tools to achieve good ranking traffic; Second, original high-quality article updates based on keyword layout. Do a good job in Google SEO site keyword planning and deployment, update of high-quality original articles related to keywords; Third, build high-interest internal and external links with original articles.

So in general, in order to get a lot of traffic through Google SEO, you must first do a good job, and then do an original high-quality article update based on keyword layout. Again, you can do high-interest keywords internal and external anchor text links. Construction, these three steps to do well, it is not difficult to get traffic quickly through Google SEO. What are the practices of Google SEO inside and outside the chain?

Zeng Dewei: The practice of Google SEO internal chain construction can be recommended through the association of the website building program. It is relatively simple and controllable to complete the construction of the inner chain by keyword correlation matching. The construction of the Google SEO chain is more extensive. Sellers can build external links through foreign industry forums, blogs, bookmarks, social networking sites, wiki sites, Q&A sites, photo sites, and video sites. What do you need to pay attention to when setting up the external chain?

Zeng Dewei: When a newcomer is doing a Google SEO chain, don’t just send it. Google’s algorithm for the last two years is very demanding on external chain construction, and it will focus on combating irrelevant spam links. Therefore, massive hairline is basically useless!

To publish the external chain, you need to find the right channel. The best published page has high weight and content relevance, and the weight is passed by DoFollow weight. This kind of link effect is good. A high-weight, high-related outer chain is sometimes several times better than a few hundred or thousands of garbage chains! Therefore, when you release the external chain, you do not ask for more, and you must pursue quality.

Hugo: After getting traffic through Google SEO, how do you convert it into store sales?

Zeng Dewei: Google SEO’s traffic is based on keyword demand, which has a high conversion rate. When Google SEO traffic reaches the website, we need to optimize the Google SEO landing page, which requires the website to clearly express the product selling point, inquiry or order conversion process.

Hugo: In the future, what is the trend of the Google SEO search engine?

Zeng Dewei: The future of Google SEO will be more biased towards White Hat Google SEO, and will get more traffic quickly. Because Google’s algorithms are becoming more and more intelligent, it is difficult for any kind of Google SEO to cheat to get a lot of traffic for a long time.

Keyword tool criteria, methods and results

Based on the experience of Authority Hacker, he believes that the perfect keyword research tool relies on five main criteria, namely:

  1. Keyword suggestions: You must find/recommended as many relevant keywords as possible.
  2. Data filtering: You must be able to easily filter large keyword lists.
  3. Search volume trend: The search trend for keywords must be displayed.
  4. Keyword difficulty: Must have a reliable keyword difficulty score.
  5. SERP analysis: Must have SERP analysis capabilities.

Authority Hacker will test six large keyword research tools for all of these criteria and then assign 1-5 levels to each standard. This will result in a total score of 25 points for each tool. (Niufeng thinks these five indicators are very reasonable and worth learning.)

Note: In order to test the “keyword suggestion” standard, the author used the word “massage” to compare the results of six tools.

1. Ahrefs Keywords Explorer (23/25 points)

Number of keyword suggestions: 5/5

Suggestion: 892,576 keywords

Ahrefs extracted the maximum number of keyword suggestions and was much higher than all other tools. Ahrefs’ keyword generator is driven by clickstream data and updates its database every month with new keywords.

Data filtering: 4/5

Ahrefs allows you to filter the entire list of keyword suggestions by search volume and keyword difficulty. Both of these metrics are cached and are always available for the entire keyword database.
This tool also provides some unique keyword metrics (and filters) for keyword suggestion lists not found in other tools, such as:

  • Click
  • Every search click
  • response rate

But it will only be displayed after clicking the “Get metrics” button.

Search volume trend: 4/5

This tool not only displays search volume trends starting in September 2015, but is further broken down based on whether the search caused actual clicks.
The search volume trend graph is visual and does not display search volume figures for the past few months.

Keyword difficulty: 5/5

The keyword difficulty calculation in the Ahrefs Keywords Explorer is based entirely on the backlinks of the top 10 pages in the SERP (no other metrics).

SERP analysis: 5/5

A very detailed SERP analysis. Ahrefs will show you the exact number of backlinks for your search results. It’s the only tool that shows the search traffic from the top-ranked pages (from all of their ranked keywords, not just your target keywords).

2. KWFinder (20/25 points)

Number of keyword suggestions: 2/5

Suggestion: 954 keywords

The tool has three types of keyword ideas: suggestions, autocomplete, and questions.
Note: KWFinder offers 200 or 700 keyword suggestions based on your membership package.

Data filtering: 4/5

Filtering with KWFinder is a breeze. There is only one drawback: keyword difficulty data is not immediately used for each keyword unless it has been previously requested by any user (unlike Ahrefs’s Keywords Explorer, which shows the keyword difficulty recommended by all keywords).

Search volume trend: 5/5

The search volume trend is well laid out in KWFinder style and contains all the data you expect.

Keyword difficulty: 5/5

They calculate based on the SEO statistics on the page on the Google homepage (DA, PA, MR, MT extracted from MOZ). In my experience, KWFinder’s SEO difficulty indicators are surprisingly accurate.

SERP analysis: 4/5

KWFinder’s SERP analysis is very simple and easy to understand. However, they are using backlink data from MOZ, which is not a perfect source of information. Maybe they should consider switching to the Majestic API.

3. Moz Keyword Explorer (14/25 points)

Number of keyword suggestions: 2/5

Suggestion: 1,000 keywords

Note: Moz has 1,000 keyword suggestion limits for any seed keyword.

Data filtering: 5/5

Although the filtering options in the MOZ tool feel somewhat limited, they provide unique semantic filters and grouping.

Search volume trend: 0/5

No Search Volume Trends data is available.

Keyword difficulty: 5/5

Moz uses the PA and DA metrics of the top ten pages of his keywords to calculate keyword difficulty. I must say that their difficulty score is very good.

SERP analysis: 2/5

Moz only provides the minimum data for the top 10 search results, such as the number of PAs, DAs, and reference domains.

4. SEMrush Keyword Magic Tool (13/25 points)

Number of keyword suggestions: 4/5

Suggestion: 440,273 keywords

Considering the excellent results of this tool (Keyword Magic) is still in the testing stage. However, this is only 40% of the number of Ahrefs recommendations.

Data filtering: 4/5

SEMrush meets all the expectations of the data you want to filter. Not bad at all.

Search volume trend: 3/5

A good standard trend chart covering the past 12 months. Instead of displaying search volume numbers for the past few months, it gives decimal scores, one of which represents the month with the highest search volume.
Note: To see search volume trends, you must leave the Keyword Magic tool and go to the Keyword Analytics -> Overview section

Keyword difficulty: 1/5

As explained in their knowledge base, SEMrush takes into account the permissions of the fields displayed on the results page to determine the difficulty of the keywords.
In most cases, their KD scores are completely wrong (based on our experience). In my opinion, this may be one of the biggest weaknesses of SEMrush as a keyword research tool.

Note: The SEMrush team discussed their keyword difficulty. They acknowledged this problem and are redeveloping it later.

SERP analysis: 1/5

SEMrush simply displays a Google SERP for a given keyword cached, with no data on the ranking page.

5. Long Tail Pro (12/25 points)

Number of keyword suggestions: 2/5

Suggestion: 893 keywords

A reasonable number of suggestions, but due to the “maximum results per seed keyword” limit, I had to run their “Google AdWords Suggestions” report multiple times.

Data filtering: 3/5

Quite a lot of filtering opportunities, but the interface may need some improvement.

Search volume trend: 0/5

No Search Volume Trends data is available.

Keyword difficulty: 4/5

Keywords The competitiveness of this tool is calculated using the page title, Majestic Trust Flow and Citation Flow, links and other factors found in the top 10 results on Google. In our keyword difficulty test, the keyword difficulty score from Long Tail Pro is the second most accurate score after Ahrefs.

SERP analysis: 3/5

A lot of reliable data. The downside of their SERP analysis is that it forces you to enter a new browser tab.

6. SERPStat Keyword Research Tool (10/25 points)

Number of keyword suggestions: 3/5

Suggestion: 149,003 keywords

Serpstat offers a lot of keyword suggestions. About 35% of SEMrush.

Data filtering: 2/5

Provide some good filtering options. However, you can’t filter or sort the list of suggestions by keyword difficulty.

Search volume trend: 3/5

Take advantage of the power of Google Trends embedding. However, it does give you a comprehensive picture of the keywords that search for words that change over time.

Keyword difficulty:?/ 5

Serpstat estimates its keyword difficulty based on a number of factors, such as the backlink profile for the top 10 search results, page rank and trust level, and page factors such as keywords in the title and URL.
The indicator was added to Serpstat in June 2017 and was not tested by the author.

About the standard explanation used above

Number of keyword suggestions

Usually, the keyword tool gives you more keywords, and the more likely you are to find a good opportunity. The only fair way to compare keyword tools is to run the same query word through each tool and record the results.
These tools use the keyword “massage”. The keyword suggestion count was taken on November 17, 2017. Since these keyword tools update their databases on a regular basis, it may be slightly different if you perform similar tests today.

Data filtering

A list of keyword suggestions is just the beginning of keyword research. In addition, you need to effectively filter this list. A good keyword tool must provide simple filtering options, regardless of which other keyword metrics these tools have, search volume and keyword difficulty are required.

Search volume trend

Now, after filtering out the list of keyword suggestions, you have some good keywords, and you need to do a separate keyword analysis. Over time, keyword search volume trends are essential to see if the searcher’s interest is rising or falling, and whether seasonality will affect it.

Keyword difficulty

Every good keyword research tool has some form of difficulty or competitive score (don’t confuse it with “competition” in GKP, which only applies to advertising). This metric must show the difficulty of ranking for any given keyword. With it, you can easily filter a large number of keyword suggestions and find suggestions that are easy to rank. Ahrefs gets 5/5, not only because it is the author’s personal favorite SEO tool.

If you still think that the author is only biased towards Ahrefs, then another keyword difficulty study by Kelvin Mah of Humanproofdesigns: Which keyword difficulty checker is the most accurate? Ahrefs also won there.

SERP analysis

Keyword difficulty can help you narrow down the list of keyword suggestions. But it does not replace the manual review of the SERP. That’s why a good keyword tool should not only give you a fairly reliable keyword difficulty score, but once you identify a potential good keyword, it will give you enough data.

Why this article doesn’t include Google Keyword Planner (and some other keyword research tools)

You may have noticed that the Keyword Tool test did not include Google Keyword Planner. This is because GKP is a special tool for PPC advertisers and does not fully assist in SEO keyword research. Google Keyword Planner has one of the biggest effects on SEO, which is that it can display the search volume of keywords. You can use the google keyword planner and the above tools to conduct SEO keyword research.

But in addition to GKP, you may be wondering why you don’t include some other famous keyword research tools, such as:

  • Ubersuggest

Because these keyword tools can not reach the professional level, that is to say, the number of keyword suggestions, data filtering, search volume trend, keyword difficulty, SERP analysis can not be achieved.


You saw the results of this article test. However, there are more things to consider when choosing a keyword research tool. All in all, your choice must depend on your level of SEO knowledge and the work you want to do. Ahrefs is an experienced SEO tool that uses this tool to get every detail, and KWfinder is the perfect choice for a new SEO, because its price is very cheap and cost-effective. Of course, you can also go to a treasure to buy a shared version of Ahrefs.


SEO and SEM terminology

What is SEO all-in-one? What does SERP mean? What is the difference between white hat SEO and black hat SEO?

2.1 White Hat SEO is an SEO optimization method that complies with the guidelines of the mainstream search engine. Contrary to black hats, White Hat SEO has always been considered by the industry to be the best SEO approach, avoiding any conflict with search engine rules, and white hats are the highest ethical standards for SEO practitioners.

2.3 Gray hat SEO, which means the middle zone between the white cap and the black cap. Compared with the white cap, the gray cap SEO will take some tricks to operate. These behaviors are not illegal, but they are also not Follow the rules and be in a gray area.

3, the keyword (Keyword)

The key word is that the user inputs the words and words used by the search engine to query, and can be any combination of Chinese, English, numbers, or Chinese and English numbers.

3.1 Keyword Density

The ratio of the total number of times a keyword or a keyword appears on a web page to other text.

The greater the number of occurrences of keywords relative to the total number of words on the page, the greater the total keyword density (unit: g/cm3 or kg/m3).

3.2 word segmentation technology

This is a unique process for Chinese search engines. It refers to the process of separating a sequence of consecutive Chinese characters without spaces in between into a single, meaningful word.

There are three main methods for word segmentation:

“I don’t know what you are saying” is divided into “No, know, you are, say, what” – this right-to-left participle method is called the reverse matching method;

“I don’t know what you are saying” is divided into “I don’t know, you, what, what to say” – this left-to-right method is called forward matching;

“I don’t know what you are saying” is divided into “I don’t know, what you are, what to say” – this method is called the shortest path segmentation.

4, spiders, robots, crawlers (crawler, robot, spider)

The crawlers, spiders, and robots are actually the same. They are web client programs like IE, which collect website content on the network and compile it into the search engine database.

5, link farm, link factory (Link farm, Link factory)

Link farms, which are a set of content-independent pages that are linked together by links in an attempt to obtain good search engine rankings or traffic. They automatically build a large number of links that are unrelated to content through tools. They are recognized as webspam, often leaving users stuck in link farms but not finding the most useful content.

6, Natural Links, sponsored links (Sponsored Link)

Natural links are links that are spontaneously created based on the content of the web page. Correspondingly, the purchase link and the reciprocal link are unnaturally formed links with commercial transactions. The sponsored link is a text link advertisement, and a frequently appearing advertisement form is a banner banner advertisement.

7, search engine rankings

In simple terms, search engine ranking refers to the location of the website in the search engine results page (SERP), the most direct reflection of the work results of SEO is the website ranking.

There are also “black words” in the ranking of the website:

7.1 by K: Cannot find information on the website in the search engine

7.2 Demotion: Searching for specific keywords in search engines can’t find website information, and web content is backward.

8, 301 redirect

URL redirection is the most viable option. When the user or the search engine issues a browsing request to the web server, the server returns a type of status code in the header of the HTTP data stream, indicating that the web page is permanently transferred to another address.

9, 404 (404 NOT FOUND)

The 404 page is the page that the server cannot provide normal information and the returned page after the user enters the URL due to the link failure or the website expiration.

However, a good 404 page will reduce the user’s irritability.

10, HTML

Hyper Text Mark-up Language, a basic hypertext markup language based on website design .

11, Hypertext Transfer Protocol (HTTP)

Hypertext Transfer Protocol, a transmission protocol for web browsing web pages.

13, page level (PR)

Page rank is Google ‘s tool for measuring the importance of a web page. Measurements range from 1 to 10 to indicate the importance of a web page. The PR of the new website is 0, and the general PR is updated every 3 months.

14, Nofollow

A property of a link that causes search engine spiders to ignore a portion of the links to those pages. The general blog comments have the Nofollow attribute. Such external links are not useful for SEO.

15, link text and anchor text (link text & Anchor text )

Anchor text, also known as anchor text links, is a form of link. Similar to hyperlinks, hyperlinked code is anchor text, which makes a link to a keyword and points to another web page. This form of link is called anchor text.

The search engine determines what the linked site is by linking the text, and generally sets the keyword as the anchor text.

16, bread crumbs (bread crumbs)

Also known as location navigation, the “breadcrumbs” architecture allows users to understand the current page hierarchy in the site.

17, Bounce Rate (Bounce Rate)

When a user enters a web page and leaves the other pages of the website within a session time, this behavior is called Bounce. The lower the Bounce Rate, the better, indicating that the user has visited more pages on the site.
