Definition

Site authority is the aggregate measure of a website’s credibility and trustworthiness as assessed by search engines and AI systems — built from inbound links, brand mentions, content quality, entity verification, and third-party citation patterns. Site authority is not a single metric — it is a composite of signals. High site authority means AI systems are more likely to retrieve content from the domain, more likely to trust it as a citation source, and more likely to use it when constructing answers. Authority is earned incrementally through consistent quality, wide citation, and verified entity presence — not through any single tactic.
