Which factors this industry fails most often

The rubric scores 19 factors. A factor counts as failed here when a site scores below 50 out of 100 on it. The last column is how many audits each rate was calculated from. Question Coverage & FAQ Presence and Media Accessibility are not scored on every kind of page: a rankings table or a paginated index has no question to answer and no image to caption. Citation-Worthiness, E-E-A-T Signals and Question Coverage & FAQ Presence lean on English-language patterns, so on a page written in another language they are scored out of a smaller total. Those rows therefore leave out every audit of a page the factor was not scored on the same scale, and every audit that did not record enough about the page for us to tell. Every other row counts every audit in this industry that scored the factor.

Where Marketplace diverges from everyone else

Relative to the whole corpus, this industry is distinctively weak on Question Coverage & FAQ Presence (+15 points), E-E-A-T Signals (+11 points), Mobile Optimization (+10 points).

It is distinctively strong on External Citations & References (-4 points), Unique Value Proposition (-3 points), Structured Data Quality (-2 points).

Question Coverage & FAQ Presence: fails on 100% of the 43 Marketplace audits it was measured on

Covering the sub-questions users actually ask is the single strongest diagnosed lever: contextual gaps and intent divergence explain most zero-citation failures. FAQ formatting by itself is not the lever; answering the questions is.

E-E-A-T Signals: fails on 100% of the 46 Marketplace audits it was measured on

No study tests author bios as a causal AI-citation lever; the real authority channel is off-site brand footprint. On-page bylines and dates are kept as best-practice hygiene at reduced weight.

Mobile Optimization: fails on 24% of the 211 Marketplace audits it was measured on

No AI-engine evidence exists for mobile signals; this is classic search hygiene (Google page experience) retained at a modest weight.
