When the university website construction meets the green apple algorithm

Baidu's move has safeguarded the interests of most grassroots webmasters and won the support of many SEO practitioners.

The reason why the Luluo algorithm came out

Baidu's search engine technology is based on hyperlink analysis (hyperlink analysis is to evaluate the quality of linked websites by analyzing the number of linked websites, to ensure that the more popular content users have in Baidu's search, the higher the ranking. Baidu founder Robin Li is the only holder of hyperlink analysis expertise. At present, this technology has been widely used by major search engines around the world, extracted from Baidu Encyclopedia.) When the hyperlink trading industry is based on the principle of hyperlink weight transfer, hyperlink intermediaries sell the links of websites with high weight to the websites with the highest weight. More and more websites join this trade alliance. With garbage or deceptive websites, the position of intelligent and fair search engines will be shaken and have good rankings, Baidu can no longer walk on the edge of algorithm vulnerabilities for these reasons.

What changes may have been made to the Luluo algorithm?

First of all, we can be sure that Baidu, like Google, also has a pr value, but Baidu has not yet published the pr value of Baidu, the website.

1. The correlation analysis between the link title and the content index of the targeted page is more intelligent, not limited to the website title, meta and content. Based on the correlation between the content of site A and site B, the content quality of site A and site B, the website update frequency, the history of website violations, and the total weight value of the website, the green tree algorithm comprehensively judges whether the link weight transmission from page A to page B is effective. When a large number of weight transmission fails, the weight of the entire site of the website will inevitably decline, and the keyword ranking will inevitably disappear.

2. The weight transfer is invalid, and the purchase process is invalid. "Quantitative change will inevitably lead to qualitative change". When the search engine finds a large number of bad external chain output, that is, weight output, it will certainly reduce the weight value of the site. This adjustment of Luluo algorithm should increase the impact of pr output on the whole station.

Spiders are extremely sensitive to the following excessive SEO, and so is the Lvluo algorithm.

1. Add hidden text and links to the web page.

2. Add irrelevant keywords to the webpage.

3. Deceptive jumps and redirects

4. Entrance page (transition page) made for search engine

5. Program generated garbage content

6. worthless content with a lot of repetition

7. Lots of advertisements and malicious code.

8. Is the dynamic page or URL hyperlink valid? By analyzing the external chain of the small station, the author found that the link? The outer chain of dynamic pages with equal dynamic parameter symbols is valid.

9. Exchange friendship links. Select sites with equal or similar weights to exchange friendship links. Can sites with Baidu weight of 7 and Baidu weight of 0 be judged as cheating?

10. Spiders should pay more attention to the correlation between the link text of the Lvluo algorithm and the content of the page they point to. When the contents of A and B are not related, A does not get the weight transfer of B, but has PR output, reducing the weight of the site;

Baidu Lvluo algorithm will definitely further increase the external chain filtering mechanism. Small and medium-sized websites that rely on the garbage outside the garbage station chain will not survive for a long time. Through website optimization, we can see the changes of the external chain through Baidu webmaster tools.
