A backlink is a hyperlink placed on one site that directs traffic to another. Search engines treat backlinks as endorsements, making them one of the strongest ranking factors in SEO. High-quality backlinks from reputable sites improve visibility, while spammy or irrelevant ones can harm rankings.

For example, if an industry blog links to your product guide, that backlink helps both referral traffic and search engine credibility.
