Look at the portal sites, and their keyword density is somewhat higher than 15%, and there is also a good ranking. The following is a summary of the important points:
1. Websites should not contain sensitive words
For example, if it is not easy to use keywords such as adults, Baidu is allowed to enter the cold Palace. We cannot compare with portal sites.
2. The content must be original
Sometimes some webmasters find that Baidu has collected thousands of pages and has reduced the number to several hundred in a few days. In fact, this is mostly because Baidu has found that your content has been repeated too many times, they will judge that such a website has no value. Of course, the portal does not have this problem.
3. The title, that is, the primary keyword, should be clarified at the beginning of the website building tutorial.
Baidu is most afraid of revision. Google is not very sensitive. Generally, after the website title is changed, Baidu won't rank it within a month. If it doesn't work well, it will enter the sandbox status. I will use my Shanxi website optimization tutorial http://www.111cn.net/for self-testing.
4. Space opening speed must be good
This is not much. When a spider comes, your website cannot be opened, and the consequences do not need to be said.
5. Links
For Friendship links, you should first check whether this site has been indexed by Baidu. If it is not included, it may be caused by Baidu K's excessive website or its quality is too low.
