First of all, let us first understand what is a cross-link and the concept of a cross-link? Ouyang Chun lists two forms of cross-links, ranging from fewer cross-linked sites to more cross-linked sites, and so on.
First of all, the first type of cross link is relatively simple, which is a single triangle cross link.
Suppose there are three websites namely A, B, and C. A chain B - B chain C - C chain A, thus forming a triangular cross-link structure.

The second type is a double triangle cross link.
You have two websites, A and B, and others have two websites, C and D. Your A website links to someone else's C website, and his C website links to your B website, and then your B website links to his D website. The D website links to your A website.

In addition, many SEOERs have always had a misunderstanding. For example, as mentioned in the double triangle cross link, you have two websites A and B, while others have two websites C and D. The websites you want to rank each other are A and C respectively. Your B gives his C a single chain, and his D gives your A a single chain. This is not a cross link. Why do many people always say cross link? This is obviously a single chain, and a single chain is linear.
