Cross linking | SEO Tips 2019
Cross linking refers to the process of linking between two sites. It allows users to reference sites with content similar to that which they are already viewing, and may be of further interest to them.
In the last few years, Google has come down very heavily on "blackhat"
optimization techniques. This has included things like cross-linking your own sites.
Cross links within your site are important to visitors as a way to find useful, related content. For example, if you have a page explaining the concept of class inheritance in an object-oriented programming language, a cross link to an explanation of the related concept of the class interface might help some visitors. From a navigability viewpoint, the idea is that is should be easy to move through all information that is topically related.
