Which signals in the scan are the strongest evidence of gaps?

In practice, the scan presents three signal types: discovery, retrieval and referrals. The strongest evidence comes from retrieved pages that include approved facts, and from any visible citations or confirmed AI referrals. If a signal lacks an approved fact, label it as partial and don't treat it as a sales signal. Read the report by comparing the same evidence over time and looking for gaps in key questions, factual consistency and the availability of structured outputs. Signals differ by AI provider, so don't take a single number as gospel; use multiple signals and track changes over time. A practical next step is to pick which gaps to fill (facts, Q&A, images) and plan a follow-up retrieval to close them.
