Links from external websites that point to your site, serving as votes of confidence that signal authority and trustworthiness to search engines.
Backlinks (also called inbound links or incoming links) are hyperlinks from one website to another. When Site A links to Site B, Site B receives a backlink from Site A. Search engines treat backlinks as endorsements, with each link signaling that the linking site considers the target content valuable enough to reference.
Not all backlinks are equal. A link from a high-authority site (like a major news outlet or university) carries significantly more weight than a link from a low-quality or spammy site. The relevance of the linking site also matters: a link from an industry-relevant blog is more valuable than one from an unrelated directory.
Backlinks remain one of the strongest ranking factors in Google's algorithm. Pages with more high-quality backlinks consistently outrank pages with fewer links, all else being equal. Ahrefs data shows that pages with at least one backlink rank 3.8x higher than pages with zero referring domains.
Backlinks also matter for AI visibility. AI models learn from the web, and pages that are frequently linked to are more likely to be included in training data and cited in AI-generated responses.
A SaaS company publishes original research on industry benchmarks. Other blogs reference the data and link back to the original study. These editorial backlinks signal to Google that the content is authoritative, improving rankings for related queries.
