Scope and evidence
Evaluated on each Organization item with a logo. The book marks this requirement ELIGIBILITY REQUIREMENT, SEARCH-ENGINE-SPECIFIC, and the scanner treats it as a gate: feature:org_logo rule: a failure makes the unit ineligible for the feature, and the report lists the feature's eligibility on its own line.
Fail conditions
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.
logo_not_okThe Organization logo {logo_url} returned {outcome}. Google requires the logo image URL to be crawlable and indexable.
logo_blockedThe Organization logo {logo_url} is disallowed for Googlebot-Image by {rule}. Google requires the logo image URL to be crawlable and indexable.
logo_noindexThe Organization logo {logo_url} is served with noindex. Google requires the logo image URL to be crawlable and indexable.
logo_unsupported_formatThe Organization logo {logo_url} is {format}. Google requires a logo format supported by Google Images.
logo_too_smallThe Organization logo {logo_url} is {width}×{height}. Google requires a logo of at least 112x112px.
logo_unreadableThe scanner could not read the format or dimensions of the Organization logo {logo_url}.
The documented fix
Point logo to a stable, crawlable PNG, JPEG, WebP or SVG image at least 112×112.

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.
