First of all, let's start by recognizing what is the concept of cross linking and cross linking? Ouyangqiu here is a list of two types of cross links, from the intersection of stops to many, and so on.

First, the first kind of cross link is relatively simple, is a single triangular cross link.

Suppose three sites are a, B, and C respectively. A chain B chain C chain A, thus forming a triangular cross link structure.

The second type is a double triangular cross link.

You have a,b two sites, others have c,d two sites, your a site links someone else's C site, his C site links your b site, and then your B site links his D site to his D site and links to your a site.

Many other seoer have always had a misunderstanding, such as the double triangular cross link inside mentioned, you have a,b two sites, others have c,d two sites. The sites you want to rank with each other are a and C. Your b gives him the C single chain, and his d gives you a single strand. This is not a cross link, why do many people always say cross link cross links? This is obviously a single chain, single chain is linear type.
