What is a backlink?

Backlinks are actually declared within the target document; in other words, regular links indicate "point to document B" in document A, while reverse links require "make document A point to document B" in document B. . For a web document, all links pointing to it from other documents are called "reverse links". The more backlinks a web document has, the higher its “popularity” is.

If there is a link on web page A that points to web page B, then the link on web page A is a reverse link to web page B.

The backlinks mentioned in SEO are also called incoming links (Backlinks) and external links. But the generalization of backlinks includes incoming links within and outside the site.
