When checking for inclusion, I found that the search engine only included the homepage of the website, and other pages were not included. What is the reason? According to teacher Ouyang Chun’s personal summary, there are nine main reasons:
1. The content of the new website is not displayed during the review period.
2. The collection station and thief station were plucked
3. The server is unstable for a long time
4. Robots writing error
5. Websites with sensitive topics
6. The website was invaded and mounted with Trojan horse
7. The domain name has been punished before
8. Being demoted after sending external links in bulk
9. Failure of the search engine itself
1. The content of the new website is not displayed during the review period.
When a new website is first included in a search engine, the homepage of the website is usually included first. Other pages will enter the search engine's review mechanism and will be displayed after the review process is completed. This process is relatively fast for Google, which usually starts to include the internal pages of the website in 2-3 days, while Baidu is relatively slow, but generally does not exceed 1 month.
Solution: Basically every new website will go through this process. What we have to do is how to shorten this process: the first is to continuously update the homepage after the search engine includes it, and the second is to add some external links. From these two aspects Speed up search engine review time for content. If you wait patiently, there will be no problem.
2. The collection station and thief station were plucked
There are countless collection sites and thief websites. Once the number of such websites increases, the content will be too repetitive or a large number of mirror websites will be generated.
Imagine that an article has been reprinted 10,000 times. How many of these 10,000 pages with the same content are truly valuable to users, and how many of them have been viewed by users?
The problem of the thief site is more serious than that of the collection site. The collection site may have a high degree of duplication of some articles, while the thief site is 99% identical. Once there are thousands of identical websites on the Internet, will search engines still stand by and watch? No wonder webmasters call such websites "junk sites."
Regardless of whether it is a collection site or a thief site, once the search engine's penalty rules are activated after quantification, the site will be punished. Generally, the most common phenomenon is that the collection drops sharply or even K deletes other pages, leaving only one homepage. Someone may come up and say: "My thief website is running fine, nothing happened at all, you are wrong." In fact, the truth is very simple. If you are the only one using this thief program, you have created several identical websites. , basically there will be no problem. If this program is not used by you alone but by hundreds or thousands of people, these websites will form a collection. When the search engine analyzes this collection and finds that there are many duplicate websites, some of them will be downgraded or even K. Drop it, keep some of it. Maybe you are one of those people who has retained that part.
Solution: The collection site can use multi-site collection, which means that you should not frequently collect several websites. You should expand your collection sources to better avoid the risk of being demoted. Thief websites can use the integration of multiple thief programs, such as integrating Sina ASK, SOSO, Baidu Q&A, etc. to increase the diversity of content. However, the thief program cannot avoid the risk of demotion. Just like a person who steals things may not be caught for the time being, but it does not mean that he will not be caught in the future.
3. The server is unstable for a long time
Search engines will visit your website from time to time. If your website cannot be opened 8 or 9 times out of 10 times or is opened extremely slowly, the search engine will treat this website as a website that is about to be closed. The website will be deleted slowly. Until the homepage of the remaining website is deleted, the search engine continues to observe whether the website is really going to be closed. At this time, we see that the search engine only includes the website due to space problems. Home page phenomenon.
Solution: Change space immediately.
4. Robots writing error
I have a student who works on an e-commerce platform. He opened a second-level domain name for each registered user. However, more than a month after the opening of these second-level domain names, they only included one home page, and no title information and no title information were displayed. Descriptive information. After he found me, I immediately found out that it was an error in writing the robots file, which was written to block search engine inclusion. However, Baidu did not fully follow the principle of prohibiting inclusion and included a home page.
Solution: Remove the robots file directly, or modify it to the correct writing method. For details, refer to the detailed parameter configuration of the Robots.txt file: http://www.gengtima.com/wangzhanyouhua/Robots.txt/
5. Websites with sensitive topics
Generally speaking, the sensitive topics we refer to refer to websites that are borderline or illegal. For example, borderline websites with pictures of beautiful women (a little more exposed and wilder), these types of websites can be easily dealt with if reported.
Illegal ones, such as applying for certificates or issuing invoices, etc. Websites in this category can easily be punished by search engines if you are not careful.
Solution: The life cycle of this type of website is generally not too long. I do not recommend making websites involving law or crime. Such websites mostly rely on luck. Sometimes, no matter how good your technology is, you can’t avoid being demoted by search engines. This is not a technical problem, but a problem with the website itself.
6. The website was invaded and mounted with Trojan horse
Search engines are very sensitive to websites infected with Trojan horses. Baidu usually lowers the ranking within a few days. This is to prevent users from browsing websites infected with Trojan horses and suffer disaster. Google will provide prompts for websites infected with Trojan horses. If the Trojan link is not dealt with for a long time, it may be demoted and left on the homepage.
Solution: When a Trojan is found, you should delete the Trojan link immediately and then find out the reason why the website was invaded. There are nothing more than two key points. One is caused by the vulnerability of the program itself, and the other is that the server is invaded and your website is also harmed. If it is a server problem, you can directly contact the space provider to solve it; website problems can also be solved. In order to avoid the irresponsibility of the space provider's staff when checking your website, it is better to do it yourself and use the method of fighting virus with virus to find Trojans. You can search for Trojans in some well-known websites. A hacker website downloads a Trojan and uploads it to the FTP root directory. Generally, Trojans have a "Trojan scan" function. Through this scanning function, Trojans existing in the website can be scanned and then removed. This is the most direct method. Don't forget to delete the Trojan you uploaded at the end. I will write a dedicated article on detailed tutorials on this later.
7. The domain name has been punished before
Sometimes the domain name you use has been used by others before. The domain name has been penalized by search engines and only included one home page. It happened to be registered by you. No matter what you do at this time, other pages will not be included. What should I do?
Solution: Normally, search engines will have automatic inspection and release mechanisms, which is equivalent to saying that including only the home page is a prison sentence for a website, and it will be released after the sentence is over. So you need to wait for a while, especially if the domain name owner and theme change, search engines will give this website a chance. In addition, you can write a letter to Google and tell them the details of your website. Never say: "Why does my website only include the home page? Please help me solve it." No one will care about this stupid question. Asking questions is inappropriate. What skills are required, but please at least describe your problem clearly. If you ask a question and others have to ask you 10 questions to figure it out, then you have a big problem.
8. Being demoted after sending external links in bulk
Search engines generally punish websites that use mass posting by reducing their inclusion and ranking. It should be said that the situation of being downgraded to the point where there is only one homepage left is quite serious. What should I do if it is no longer possible to rein in the cliff?
Solution: First reduce the optimization traces in the site to a very low standard. For example, your original keyword density is 9%, you can reduce it to 3%, etc.; add at least one original article every day; add at least 5 articles every day High in the industry
Quality external links. Being plucked is painful and the recovery process is arduous. All that's left is to wait for the release of search engines. However, this method is not 100% successful, and there is no 100% successful method. As long as you do this, at least the chances will be greatly improved. In most cases, it will take about half a year to return to normal after the mass sending is downgraded, so the correct mass sending method is very important.
9. Failure of the search engine itself
Some students who are new to SEO find it incredible that the websites of big companies like Baidu and Google still have problems. In fact, Google rarely makes such low-level mistakes, but Baidu makes them as commonplace. There are many cases where only the homepage is left in the collection. We often encounter some students complaining in forums or various places.
Solution: Under the premise of ensuring that there are no problems with your SEO methods, continue to work on your website. It will be restored within a week if possible. In some special cases, it may take up to 3 months.
