What is a backlink? A backlink is a link from one website to another. If you’re a website owner, a backlink is a link from another website to yours. Backlinks are used by Google as a search engine optimization (SEO) ranking factor.
While the definition of a backlink is simple, the process of acquiring them for SEO gains is fraught with misunderstandings and disagreements, plus a lot of manipulation in the early years of SEO.
While SEO myths still exist today, the process of “link building” has greatly matured and, for the most part, is no longer a spammy practice.
Google uses backlinks as a ranking factor because they act like “votes” for your site. If someone is linking to you, it’s usually because you provide more valuable information or are a subject matter expert. Both of those reasons for linking are a “hey, this site is great” signal for search engines.
