Link pyramid tier 1 tier 2 tier 3
Inbound links for SEO consist of anchor and non-anchor links.
Anchor links contain a primary search term, because such a query plays a crucial role for SEO performance.
Non-anchor links carry equal weight – this includes bare links, while user interaction is important because it provides a route for bots; search engines access your website along with internal pages, which is useful your project.
I provide tools like Majestic, SEMrush, and Ahrefs. If there are fewer links on a particular platform, I report on the service with a larger number of inbound links because of delays in indexation.
