1. Frequently modify the title or description of the website. After the title and description of the website are fixed, it will form a memory for search engine crawlers. Because it will form a habit, there will also be a fixed ranking and weight. If it is modified frequently, it will lead to K. Therefore, it is recommended that all webmasters should not frequently modify the website TDK when the website has a fixed ranking and weight unless it is absolutely necessary. .

2. The website uses collection software to collect content, which causes the website content to contain too much copied content. This is also one of the main reasons why the website is K-ed. At this point, it is also the pseudo-original content that everyone often mentions, but remember, pseudo-original content must also be valuable content.

3. The website is frequently revised and changes too much. Websites are frequently revised, so every time they are revised, search engines may have to re-recognize your website. If there are too many revisions, you will not discuss it.

4. The website server is stable. According to the survey, the stability of the server is the primary factor in SEO and is also an important reason for the website to be K. If your website server is unstable and cannot be opened at all times, or crashes at all times, search engines will not like such a website, let alone users. Therefore, if your product is good enough in the industry, you must choose a high-end server to improve website services, increase the speed of website opening, improve user experience, and gain more favor from search engines.

5. The friendly link website is K. If your website is operating normally and has not made any major changes, but the website is still being K’ed, then you should consider your own friendly links instead. If our friendly link website is K, then we ourselves will also be implicated. From this point of view, when webmasters usually operate their own websites, they must find high-quality websites to exchange friendly links.

6. Over-optimization of the website: If your website is suddenly K-listed, but none of the above five factors appear, then over-optimization is likely to be the reason for the K-listed website.
