It can be said that the search engine algorithm is inseparable from the link, so the link is also one of the essential factors in the search engine, so far the link algorithm will become more and more complex in the future. The search engine has four basic methods to evaluate the webpage links:
I. Number of links:
Use the link command to query reverse links of a website, such as link: www.SEO-service.com.cn. Generally, websites with a large number of links have fewer links and are ranked higher. However, not all links are equal.
2. link quality:
Blog: I believe everyone is familiar with it. In the blog community, everyone has their own opinions and ideas, but some people have more valuable opinions than others. There is no difference in opinions expressed by creating links through soft texts. When a link to a Web page is recognized by that web page, the search engine checks the popularity of the link of the source site to determine the weight. Therefore, if a highly authoritative website is linked to your website, it will give some of its authority to your website. Search engines classify the top Web page ranking factors as links from many high-quality sites, or even more complex. The search engine uses mathematical methods to calculate the number of links transferred to the authority of each link-a highly authoritative webpage with only five links is transferred to the authority of each link page with 50 links the authority of a Web page is the same, this theory only has so much authority, and the more links there are, the lower the recommendation value for each linked webpage.
3. text links:
The text of the link clicked by the visitor is very elegant. Text links are a key factor in search request ranking in search engine algorithms. search requests tend to return the URLs that contain search request keywords in text links.
For example, a webpage on an "Seo" website attracts many links for "Seo service, therefore, Seo websites with search requests containing these words rank higher than before.
4. Link relevance:
Links from content-related sites are also a key factor in the search request ranking. When we mention the following "content relevance ". Content Relevance refers to information about a topic (or topic or title). It is not enough to use similar words for text links, because words can have different meanings in irrelevant theme. In addition to text links, the search engine can view the words surrounding the text links, and view the words on the entire webpage or even the entire Link source site. Why? Because sites related to the search request subject provide more links than other sites.
Casual links from popular sites and links from highly popular sites do not have the same authority.
A search engine can consider so many complex factors within such a short period of time between a search request and a search result. This is a very fast computing speed, but the search engine still does. Search engines believe that the high web page ranking factor is those with many high-quality links. It is believed that the ranking factor of high search requests is those webpages with many access links. These links come from many content-related sites and contain search request keywords in text links. Note: elegant elegance is also exploring how to improve the popularity of webpage links.
