Inbound links for SEO are divided into anchor links and their non-anchor counterparts.
Anchors are linked to a primary search term, since the key query plays a crucial role for SEO performance.
Non-anchor links are equally significant – these are plain URLs, and the ability to click matters as it creates a path for search robots; search engines access the site and subsequent pages, which benefits the site.
Updates are shared through ahrefs. If there are fewer links on a particular platform, updates are provided on the tool with a larger number in backlink volume as a result of indexing lag.
