Having a website K can be said to be the biggest blow to website builders. As an SEOer, it is very important how to effectively prevent your site from being K, and how to quickly find a way to include it again after being K. This article only summarizes some possible reasons for being Kled. As for the solution, just ignore these reasons.
1. The instability of space
This is a very common reason for being Ked, especially due to the strict filing requirements, many people have placed their sites abroad. In foreign spaces, due to one or other reasons, many times the site cannot be opened inexplicably. leading to spatial instability. Also, because there are many IPs in foreign countries that can be used at will, when our site cannot be opened, many people choose to change IPs at will. Or what's more, not only the IP has been changed, but the physical space has also been changed. It doesn't matter if this operation is not very frequent, but if it is very frequent and random, the site will be easily deleted.
2. The website was attacked
There are many forms of being attacked, such as gaining our permission to insert illegal advertisements or virus-infected code into our pages; some are DDoS attacks, which cause the site to open quickly and slowly, or sometimes not to open at all; and There is a CC attack. The IP of our site has been rising sharply for no reason, and finally the site cannot be opened. If these reasons persist for a few days, the website is likely to be K. This reason is the same as the instability of space.
3. Excessive website collection
What is over-collection? It may be that the content of the same site has been collected for a long time, resulting in the content being too similar. Some people enter keywords to collect content, but they don’t know that the content may be from 2001 or 2002. These old contents are published to our site because they have keywords. This kind of content can be said to be completely outdated content, which can easily lead to the site being K-ed. The technical staff of Dongou Pump and Valve Network www.dopv.cn encountered such a case where an enterprise website was K-ed.
4. Over-optimized website
Generally speaking, over-optimization does not mean too many internal links or too many keywords. The key is the abnormal sudden increase or decrease in some data. For example, for a site that buys black links, the black links are stable in the first few days, search engines also index these external links, and the number of these external links is very huge. However, black links are very unstable. After a month or a few weeks, we quietly discovered that these links were gone. The daily snapshots of search engines can also detect abnormal changes in these data. At this time, it is very difficult to It is easy to cause the site to be hacked. Of course, there is also a sudden increase or decrease in content. A lot of information is added today, but it will not be moved for the next few days. This way of adding information can also easily cause the site to be K-ed.
5. The content and text are not on topic
For example, the theme of our site is the webmaster category, and everything in it is about losing weight or slimming down. Generally, such a situation will not be K in a short period of time, but when our site has been around for a long time and Baidu's spiders suddenly discover it, such a site is also the most likely to be K.
The above points are some of the reasons why some websites have been K-ed by me personally. They may not be of much use. I just want to inform everyone that you should be on guard against these reasons and don’t let the site you have worked so hard to build be ruthlessly plucked. Immediate discovery of the cause and correction will make our site healthier.
