Backlinks for SEO include two main types: anchor and non-anchor backlinks.

Anchor links are linked to a key query, since such a query is essential in search engine optimization.

Non-anchor backlinks are equally significant – these are plain URLs, while clickability plays a key role as they offer a route for search robots; crawlers navigate the target page along with internal pages, which is useful your project.
