What is Backlink?
A Backlink is a link from one website to a page on another website — historically one of the strongest signals search engines use to judge a page’s authority and trustworthiness.
Who Is It For?
Backlinks are tracked and built by SEO teams, and increasingly matter to content teams producing the kind of original research or data that naturally earns links.
How Is It Used?
Backlinks are used as a trust signal — both for traditional search rankings and, increasingly, as one input AI models weigh when deciding which sources to treat as credible.
- Earn backlinks through original research, data, or genuinely useful content worth linking to
- Audit backlink profiles for spammy or low-quality links that could hurt rankings
- Track competitor backlink profiles to find gaps and opportunities
- Treat backlink quality — the relevance and authority of the linking site — as more important than raw quantity
