Evidence record EV-0013

FAQ blocks and structured data showed no citation effect within a domain

An observational study of about 2 million AI-engine citations (preprint) found that FAQ blocks, structured data and Core Web Vitals had positive effects on citation in pooled data that reversed or fell to zero once domain fixed effects were applied.

Evidence class: Preprint. Unreviewed. Many are by one author or a small team, and some authors have a stake in the result. Most AX research is in this class today. Pattern tags: discovery, measurement.

Effect, as the source reports it

  • Effect of the standard answer-engine checklist (FAQ blocks, structured data, Core Web Vitals) on citation frequency. Baseline: Pooled data: positive effects. With the change: With domain fixed effects: effects reverse or collapse to zero. Direction: no-change. Size: Reverse or zero within domain (Simpson's paradox). Sample: About 2 million citations; 10,000 pages from nineteen B2B SaaS workspaces; six months.
  • Prompt-content alignment as a predictor of citation. Direction: increase. Size: beta = +0.37, 95% CI [+0.33, +0.41]; the dominant page-level predictor. Sample: As above.
  • Domain-level AI authority versus the strongest non-alignment page feature. Direction: not-applicable. Size: About six times larger in mean absolute SHAP value. Sample: As above.

Agent profile

  • Models: ChatGPT, Claude, Google AI, Gemini.
  • Note on models: Four commercial answer engines, as products; model versions not stated in the abstract.
  • Run dates: Six months (dates not given in the abstract).

Conflicts of interest

None declared in the abstract. The data come from nineteen B2B SaaS workspaces and the abstract does not say who operates them; the full text was not checked.

Limitations

  • Preprint, not peer reviewed.
  • Observational; causal claims are limited.
  • B2B SaaS pages only.
  • Measures citation, not agent task success.

For designers

Adding FAQ markup or structured data is not, on this evidence, a reliable way to get cited by answer engines. Content that matches what people actually ask carried far more signal.
