Link pyramid tier 1 tier 2 tier 3
Backlinks for SEO consist of anchor and non-anchor links.
Anchor texts are linked to the main keyword, because the key query plays a crucial role for SEO performance.
Bare links are equally significant – these are plain URLs, while clickability matters because it creates access for search robots; search engines access the target page along with internal pages, which is useful your project.
Updates are shared through tools like Majestic, SEMrush, and Ahrefs. When the number of links is limited for one of the services, I report on the service with a larger number of backlinks because of delays in indexation.
