2.？ How to do SEO?

Of course, SEO depends on searching websites. Now the world's largest search site is Google, and Baidu is probably the fourth and fifth, but in China, Baidu is undoubtedly the leading market, with 80% share. So the SEO we are doing now is Baidu's SEO by default.

How is Baidu's search content presented?

First of all, Baidu's robots will crawl and crawl websites on the Internet, and incorporate webpage content and HTML code into Baidu's database.

The second step is preprocessing, which will extract words from the web page, segment words, remove stop words, noise and repetition, extract keywords to establish an index, and finally calculate the weight of the web page according to these contents.

The weight of web pages determines the ranking of web pages in search.

The third step is ranking. Baidu will sort the web pages in the database according to the calculated weights, and then filter them, which is finally reflected in the order of search results pages.

Weight value

Here we should focus on the weight value.

Baidu's name is weight value, and Google's name is pr value, both of which are used to show the importance of the page. As mentioned above, the weight value determines the ranking order of web pages in search results.

There is no doubt that the higher the search results, the higher the probability of being clicked, but to what extent?

According to AOL's data, in addition to advertising, the number one click reached more than 40%. After the second page, it is basically less than 1%, and the fourth page can be ignored. Of course, this is an average, and the specific keywords should be analyzed in detail.

The weight value is from 1 to 10. The higher the value, the greater the weight. In addition to analyzing the content and structure of web pages, the number of high-quality reverse links will also increase the weight value.

So we do SEO optimization, that is, to find ways to improve the weight value.

In terms of external links, the most important thing is to need friendly links. As for the direction of BD, it is usually the responsibility of operation.
