Before Baidu's new algorithm, the keyword density of the graduation thesis on the site of the Chinese papers union reached 5.1%, which is also in line with the traditional keyword density range of 2%-8%. The keyword ranking of the site's graduation thesis is always within the range of 2-5 on the homepage. At that time, I also analyzed the keyword density of the top 10 websites, and found that it was basically between and. It can be seen that in Baidu's old algorithm, the keyword density has a high weight.
After the 7.14 Baidu big adjustment, the keyword of the graduation thesis on the Baidu homepage can be simply described as being big cleaned. At that time, three of the four most ranked sites were on the second and later pages of Baidu, and the sites in other locations were also changed, including, of course, the Proceedings of the Chinese society. The advantages and disadvantages of the new Baidu algorithm and whether the new algorithm meets the customer experience are not discussed here. What webmasters need is to constantly adapt to the changes in search engines, whether or not it looks reasonable.
Not to mention, Baidu's current ranking tends to be relatively stable. The author once again analyzed the keyword of this thesis on several sites on the Baidu homepage. Except that the keyword density of the first site still reaches 3.5%, other sites are basically less than 1%, and some are even only 0.3%! It can be seen that Baidu had at least some resistance to SEO after the new algorithm. I also searched the keyword of the generation thesis, and found that in addition to the highest site keyword density, other sites basically maintained the same density as the graduation thesis within 1%.
This shows two problems: first, the weight of keyword density in Baidu's new algorithm is reduced. Second, Baidu homepage only has one keyword with a high density and is generally ranked first. Of course, the second point is to be verified. We also hope that seoer can provide more experience and evidence. In addition, it should be emphasized that the original content weight is enhanced in the new calculation method.
