A backlink is an inbound hyperlink from one website to another. Backlinks remain a significant authority signal in traditional SEO — and continue to contribute to AI search authority by indicating that independent, external sources consider a brand’s content worth referencing.
When authoritative external sites link to a brand’s content, they signal to AI systems that the content is credible and relevant — contributing to topical authority and overall source credibility. High-quality backlinks from industry publications, authoritative directories, and recognized platforms contribute more to AI citation authority than volume of links from low-authority sources.
