Scope and evidence

Evaluated on page (P). The book marks this requirement DOCUMENTED RECOMMENDATION (the check itself is a house convention).

Info when the string value of name, headline or description in a registered-feature item does not occur in the page's visible text (§3.4) after normalization. Informational, because formatting differences make exact matching unreliable.

Observations

Each condition has a stable code and a reason template. The evaluator fills the placeholders from observed values only; no sentence in a report is generated.

  • not_visible

    The {property} value “{value}” of the {type} item on {url} does not occur in the page's visible text. Google says: "Don't mark up content that is not visible to readers of the page."

Sources, quoted

These are the passages the rule rests on, stored once in the knowledge base and emitted exactly as written. A citation marked for specific conditions appears only on findings with those codes.
