A link from one website to another that acts as a signal of endorsement and helps search and AI systems judge authority.
A backlink is a hyperlink on an external site pointing to a page on your own. Search engines treat backlinks as votes of confidence, weighing them by the linking site's own authority, relevance and the trust it has earned. Not all backlinks are equal: a single editorially placed link from a respected, topically relevant publication typically outweighs many low-quality or automated links.
