If the website is hacked, first look at the reasons.

1. Check whether the keyword density of the website is too high, whether the keywords are stacked, and whether the use of tags such as , , and is correct. Used too much.

2. Are there too many internal links? For example, if there are N many links in an article, under normal circumstances, the new site will have relatively few internal links.

3. Are the anchor texts of external links too concentrated? For example, if you are a website that sells anti-acne products, all the external link text is "acne products", which is obviously inappropriate.

4. Are most of the external links composed of forum signatures and blog messages? Are a large number of forum signatures and blog messages filled with the same spam replies such as "like, support"?

5. Website navigation, ZAC said in "SEO Practical Code" that the full-site keyword link in the footer is likely to be the reason for the downgrade.

Adjust the website based on the above points, and then all you have to do is wait patiently. The most important thing after being Ked is not to be impatient, and do a good job in creating content and external links during the K period. When you are not paying attention to Baidu, you can be more considerate of users when building a website.
