Most webmasters and SEO optimization practitioners understand that if you want to do a good job in website SEO optimization, you must do a good job in internal optimization (also can be understood as the optimization of internal links).
What is internal linking?
Internal links refer to mutual links between pages under the same website domain name (also known as in-site links).
For example, the home page links to the channel page, the channel page links to the content page, the content pages link to each other, and the inner page links back to the home page, etc., all belong to the website internal chain.
Then, what is the role of the internal link, and how does it help the SEO of the whole site
The internal link of the website is conducive to crawling the content of the website

In this way, even if the website has many products and articles, the search engines will not be able to crawl them, which will eventually affect the inclusion. If we do a good job of internal links and open up the two meridians of Ren Du and the eight meridians of the website, then the search engine crawling will be unimpeded, and it will be more conducive to crawling the content of the website.
Internal links on the website increase user stickiness
What is user stickiness? That is to say, a user can browse multiple articles on the website and stay for a long time.
For example, a user reads an SEO article and finds that some related articles are recommended on the right side of the website, which happens to be what he is interested in and wants to know, then the user will click to read these related articles, so that the user stays on the website for as long as possible. The longer it is, the more pages you read, and the search engine will think that the content of this website is very helpful to users, and will give it a good ranking.
Internal links on the website can improve the ranking of keywords
Any page on the website, including the homepage, product page, category page, etc., is weighted, but the weight of the homepage will be higher, while the weight of product pages and category pages will be slightly lower. , can pass the weight to other pages. The higher the overall weight of the website and the larger the website, the more obvious the role and value of the internal chain.
Summary: Large sites rely on internal links, while small sites rely on external links. If it is a small website, then more need to rely on external links to improve the website ranking; and for large websites, as long as the internal links are fully developed and the internal links are fully utilized This sentence fully reflects the role and value of the internal chain.
