Backlink

A link from one website pointing to another, used by search engines as a vote of authority and relevance.

Full definition

Backlinks are one of the most important ranking signals in Google's algorithm. A backlink from a high-authority, relevant domain signals to search engines that your content is trustworthy. Not all backlinks are equal — links from topically relevant, high-domain-authority sites carry far more weight than links from low-quality or unrelated pages. Tactics to earn backlinks include digital PR, guest posting, broken link building, and creating link-worthy assets (studies, tools, original data). Google's Penguin algorithm penalises manipulative link schemes, so the quality and natural acquisition of links matters more than quantity.

Real-world example

A fintech startup earns a backlink from Forbes after being quoted in an article about cryptocurrency trends, causing their target keyword to jump from position 14 to position 4.
