How many types of on-site links can you possibly have on your website? You might be surprised at the fact that there are so many different ways to categorize internal links. For example, some people speak of incidental links which are the links to so-called incidental pages like “About Us”, “Contact Us”, and “Testimonials”, etc.
Every logical SEO audit or website review can make at least a quick inspection of on-site links. In fact, the on-site linkage is the key element of any website because badly placed links, broken links, obscured links, noisy links, deceptive links, et. al. can create chaos for the crawlers and/or user. Search engine optimizers should spend far more time examining the on-site links as compared to the off-site links. However, you must not completely throw off-site link analysis out the window.
