Authority Signal
Evidence an AI engine uses to judge whether a source is trustworthy enough to cite — links, sameAs references, knowledge-graph presence and reputation.
What is an authority signal?
An authority signal is any piece of evidence an AI engine uses to judge whether a source is trustworthy enough to cite — backlinks, sameAs references, Wikidata presence, expert authorship and consistent reputation across the web.
Engines do not cite at random: they prefer sources they can trust. Authority signals are the proof points that earn that trust.
Authority is assembled from many signals: who links to you, whether your identity is corroborated by sameAs links and knowledge bases like Wikidata, whether content is attributed to credible authors, and whether your facts stay consistent across sources. Together they tell an engine your content is reliable.
In AI search these signals decide inclusion, not just ranking. A weak entity with thin authority is easy to omit or get wrong; a well-corroborated source is the safe one to quote. Authority is therefore the substrate on which E-E-A-T and brand-entity strength are built.
SkuLift connects authority to outcomes: its Citation Authority Score scores the authority of the sources an engine actually cited for a brand, so authority work can be measured against share of voice rather than assumed.
