AI Visibility Glossary
Trust Signal
Why it matters
AI engines prefer to recommend brands backed by trustworthy sources. Weak trust signals cap your visibility even if you publish good content yourself.

Citation rate is how frequently AI engines cite a brand or its website as a source when answering questions in its category. A high citation rate means the engine repeatedly leans on your content to ground its answers.
Source diversity is the range of independent domains and publishers that reference a brand. A brand cited by many different reputable sources is more resilient and credible in AI answers than one cited by only a handful.
Expert mentions are references to a brand in expert, editorial, or analyst-grade sources — the kind of coverage that carries outsized authority. AI engines weight these heavily when deciding who to trust and recommend.
The Signal Score is Top Citation Signal's 0–100 composite measure of a brand's AI visibility. It combines eight weighted signals — citation, trust, entity strength, coverage, source diversity, consistency, freshness, and expert mentions — into one comparable number.
