First, the main reason why the website is not included

1. Website has a bad history before the domain name.

Before buying a domain name, check whether the domain name has been registered. If you have registered before, you need to check whether you have been punished by K and search engines before. By the way, I'll teach you a few ways to see the house:

(1), to the domain name inquiry center, such as Wang Wan. If you have registered before, be careful to see if you have been punished by search engines.

(2) Use the site to explain the inspection method. Site:+domain name. If the inclusion degree is zero, but there are many external links, the domain name is K.

(3) If the URL directly entered in the search engine is recorded (http:// is required, but the site is not recorded, it may be crossed by K. ..

2. The website server space is unstable.

The factors that affect the instability of website space are: the virtual host IP is blocked, the server is frequently down, and the space access speed is very slow. Search engine spiders come to crawl your website. If they can't open or are too slow, spiders can't catch them. Over time, the number of spider visits will only decrease. It is said that the instability of space is one of the important factors that the website is not included. Pay attention to this when buying space.

3.robots protocol file is not set correctly.

Some novices don't know much about the robots protocol file, but search engines are forbidden to crawl or inadvertently modify the robots protocol file, which makes spiders unable to crawl the content of your website, so they can't be included. It is best to check whether the settings are correct in the robot in Baidu webmaster platform tool. If you don't know anything about robots, you can check with your programmer or ask my Shanghai Lao Zhang SEO blog to help you.

4. The website is frequently revised.

Don't revise the website frequently after it goes online. Baidu's most unfriendly operation is to change the domain name, change the space and modify the title of the home page. It may not be ranked or included for months. The best way is to think ahead before going online, and don't change it easily after going online. Website revision will definitely affect the inclusion, and frequent revision is also one of the important factors that lead to the website not being included. Because of your revision, all the codes have changed. Because spiders can only recognize codes, your revision will give Baidu spiders a new understanding of your website.

5. The overall weight of the new station is low, which affects the inclusion.

The new website just launched has a low weight. Even if your article is original and rich in content, the search engine will not include it. The most important thing at this time is to increase the weight. If the weight is high, the article will naturally be included. This is a collection cycle. Generally, the new website is included first, and then the pages included in the content are slowly released. This cycle takes 1.2 months.

6. The quality impact of friendly links on the website is included.

We must be careful when exchanging friendship links. Before the exchange, you should check the basic situation of the other website in the webmaster tool. Good quality or weight is exchangeable. Don't communicate with unhealthy, junk or degraded websites. The quality of friendly links is also one of the factors that affect the exclusion of websites. Here, you can generally check the friendly links in the third webmaster platform tool once a month.

7. Lack of high-quality external links outside the website.

At present, the high-quality external links of the website still have a certain effect on the ranking of the website. The lack of external links or too few high-quality external links is also one of the reasons that affect the website's non-inclusion. Publishing relevant external links of high-weight platforms can attract spiders and improve the speed of website collection.

8. Excessive website optimization

The website is deliberately optimized, which will be considered cheating by search engines. For example, piling up keywords, hiding words, too many anchor texts in articles, too many anchor texts pointing to the same keyword, too many friendly links, etc. When websites do this, they are usually punished. Once identified as cheating by search engines, K Station is not far away, and natural websites will not be included.

9. The website contains gray content.

The website contains some words or phrases that are not allowed and prohibited by law, and sensitive words appear on the page. Pornography, gambling and blogs are all excluded by search engines, and of course websites will not be included.

10, the originality of website content is low.

Some website articles are not original or plagiarize others' content, so they can be used directly after plagiarism. This is what search engines don't like the most. Search engines like fresh, non-existent content that can solve customer problems. Content that is too similar or directly included is one of the important factors that the website does not include.

1 1. There is cheating in website optimization.

The existence of cheating in website optimization directly leads to the website not being included, and in serious cases, it directly lowers the right and k stations. Cheating mainly includes hidden words, hidden links, junk links, buying and selling links, linked farms, hidden pages, PR hijacking, door pages, jumps, large stations and so on. These are all black hat SEO, I hope you don't use them.

12, the website structure is too deep.

If the website link is too deep, it will affect the spider's crawling to the search engine, and the spider will lose its way. After a long time, spider visits will decrease, and finally the website will not be included. It is generally recommended to be within three floors.

13, a new search engine updating algorithm

Search engines often update their algorithms. Sometimes your website optimization after updating does not conform to its algorithm, which will also lead to the website not being included or being included less. Webmaster friends don't have to panic. As long as we do a good job in basic optimization and update high-quality articles, the website will soon be re-included.

14, the website has security problems.

The website hangs a black chain and implants malicious code, which seriously affects the security. Search engines will make judgments, resulting in websites not being included or being included less.

Second, the website is not included in the solution.

At the beginning of the 1. website, check whether the domain name is registered and healthy. Domain names punished by search engines are not registered.

2. Try to choose a regular, big brand, stable, fast and fully functional space provider for the website space.

3. Set the robots protocol file correctly. If the setting is wrong, modify it and check it on Baidu webmaster platform.

4. After the website is launched, frequent revision is prohibited. If it is absolutely necessary to modify, please add modification rules to Baidu webmaster platform and apply for site closure protection, so that the website can be restored as soon as possible.

5. When exchanging friendship links, pay attention to the relevance, the number should not exceed 30, whether it is healthy or not. After the exchange, check whether your friendship link links to K's website. If the other party is K, your website will also be implicated. At this time, you should remove the other party's link at the first time.

6. Release high-quality external links of high-weight platforms in a planned and step-by-step manner, paying attention to relevance and diversification.

7, website optimization to avoid over-optimization, keywords can not be piled up, anchor text naturally appears, do not use cheating.

8. Gray words appear unintentionally on the website, and sensitive words should be modified or deleted in time.

9. The content of articles on the website should be kept original as far as possible, or the content of pseudo original and pseudo original should be revised by more than 80% as far as possible, so as to reduce similarities and facilitate inclusion.

10, the website uses formal technology and white hat SEO optimization, which is conducive to inclusion and ranking. Don't use black hat technology.

1 1, the general website structure suggests three layers, and more than three layers are not conducive to spider crawling and website inclusion.

12, the website should check the code regularly, and remove the black chain and hanging horse in time when it is found. Back up regularly, just in case, and make the website safe.

In fact, there are many factors that are not included in the website. As SEO personnel, we should learn to analyze, find out the reasons for not being included, and solve them. SEO optimization started before the website was launched. After the website goes online, we need to check the website code regularly, analyze the website log and record every adjustment and modification, so as to make corresponding countermeasures after the website is not included.
