What does an external link mean for SEO?-

Help search engines analyze relevance

Relevance is the most important indicator of the quality of search results (to judge the relevance of pages and keywords). At first, the search engine judged the relevance. As long as the “weight loss method” appeared on the page multiple times, and even the keywords were piled up, the search engine thought that this page was related to the “weight loss method”. Later, search engines turned to see what others said, that is, to judge relevance through external links and anchor text.

The number of external links and the quality of external links determine the weight of this website to a large extent, and also determine the website’s ability to obtain ranking and traffic capacity from search engines. From the perspective of search engines, if the links on the entire network are natural, then it is most important to get the most links and the best quality pages, otherwise you will not get a lot of high-quality links; The webpage and website pointed to by the website should be important, which is equivalent to a certain number of authoritative voting approval; the anchor text used for the link is the description of the main content of the linked page.

Increase website weight and trust

The quantity and quality of a website’s external links determine the weight and trust of this website to a large extent, and also determine the website’s ability to obtain rankings and traffic capacity from search engines.

Links are similar to voting. The number of votes, the status of the voter, the profession of the voter, the relationship between the voter and the voted person all determine the size of the role played by the link. The number of votes can determine the popularity of a webpage, and it can also be equated with the degree of importance; the higher the voter’s status, the higher the value of the vote; if the industries of the voter and the voted person are related, Then this vote will be more convincing. If a person who is in construction says that another person has a high level of humanistic attainment, he will generally not have too high credibility; if the voter and the voted person are a family (internal chain) , Then the value of this vote will also be lower than the vote of an outsider (outside chain).

Increase website inclusion

Page indexing is the basis of rankings. You cannot talk about rankings unless you enter the index database. Data observation and experience have shown that the number and quality of external links have a crucial impact on the total number of pages that a domain name can drive (because external links affect the weight to a large extent).

For websites with normal weight, search engines will only crawl 3-4 layers of links. If it reaches PR7 or PR8, the inner page that is seven or eight clicks away from the home page can also be included, thereby improving the overall indexing ability (the higher the weight, the deeper the spider crawls him).
