Backlink Definition & Meaning

What Is a Backlink?

A backlink is a hyperlink on a website that points to a web page on another site and is a key ranking factor for off-site search engine optimization. Backlinks are also known as inbound links or incoming links.

Backlinks are considered to be an endorsement of the content that’s being linked to on a website from other domains. This vote of confidence means other site owners are vouching for the expertise, authority, and trust of the target URL as long as the backlink is a dofollow link.

Dofollow backlinks transfer PageRank authority (i.e., link equity) from the origin page to the linked URL. Nofollow links tagged with the rel=”nofollow” attribute, on the other hand, may not pass any link equity to the target web page. That’s because the nofollow tag informs search engine spiders not to crawl the hyperlink or pass any link equity to the target page. However, in 2019, Google changed its algorithm system so that nofollow attributes are now considered to be a hint and not a directive.
