A website being dropped by a search engine generally means that no information related to your website can be found on the search engine. You can site the website URL on the search engine to see if any information related to your website is displayed. If no relevant information is displayed, it means that your website has been hacked. But the premise is that your website was indexed by search engines before, but then it was not indexed and the indexed pages were deleted by search engines. It will take some time for the new site you just submitted to be included.
Based on my experience, I can summarize the main reasons why websites are K-ed as follows.
1. Website content: Generally, websites with pictures of beautiful women, pornographic content, and politically sensitive issues are easily deleted by search engines. In addition, if the content of your website is basically collected, it will be easily deleted.
The solution is that the website should not contain information tabooed by search engines, such as pornography, gambling, and politically sensitive topics, and the website content should not be entirely collected, and the content should be updated regularly.
2. Key words are deliberately superimposed
Some SEO novices or those who do not understand SEO may write the title tag of the website very long, and write a large number of keywords here. In addition, they will also pile a lot of keywords and keywords in the keyWord and description tags. Website irrelevant keywords, this behavior of stuffing website content with meaningless keywords is also one of the important reasons for being K-listed by search engines.
Solution: Set keywords appropriately in the title, keyword, and description tags in META.
3. Hidden text
Use CSS code to hide keywords, or set the color of keywords to be the same as the background color. In this way, the user cannot see it, but the search engine can "see" it. The search engine will think that it is a keyword or an anchor text link. Now search engines can easily detect this kind of cheating behavior, and some people may be punished by search engines after reporting it.
Solution: Remove the hidden text, then appeal to Google and Baidu and wait for them to re-include it.
4Group messages
Bulk sending: A large number of external links to the website increase in a short period of time, and the anchor texts of the external links are all the same. Group building: In addition to the same judgment as mass sending, another point is that the IPs are often the same.
Solution: Change the keywords of the website, then submit it to the search engine and wait for inclusion
5. Sites with blocked links on the website.
When we exchange friendly links, we should always check whether the friendly links are stable. If the website with a friendly link is K-ed, we should immediately contact its website administrator to negotiate to remove such friendly links. In addition, when exchanging friendly links, you need to check whether the other party's website has the above four conditions, and if so, give up the exchange.
Solution: Delete problematic links.
6. Website service issues
As the most basic element of SEO, the stability of the website server is directly related to Baidu's credit evaluation of the website. The website server is unstable and the website cannot be opened. The direct consequence is that Baidu's evaluation of the website becomes lower. Once or twice is okay, but if the spider comes several times and cannot crawl the website content, it will think that the site is abandoned, and it is still good to stop taking snapshots. If it is serious, it will directly K-site.
Solution: Use a stable server when building your website. If the server is unstable, replace it as soon as possible and don't delay. My website, MFA Shijia, was dropped by search engines because of server problems.
The above six points are the reasons why websites are most likely to be K when I do SEO. We should try our best to avoid the above six points when doing SEO. Of course, there are many factors that lead to a website being K-ed, such as the details of the website, the addition of a link factory to the website, etc.
