Backlink

A link from another website pointing to yours. Backlinks signal authority to Google and other AI search engines. Quality matters far more than quantity: one link from a Tier-1 publisher (Forbes, HBR, industry-leading sites) outweighs 50 links from low-authority directories. Modern AI search engines also use backlinks as citation candidates - your content is more likely to be quoted by ChatGPT if it is well-linked.
