    Question-formatted headings

    What it checks

    AI answer engines directly match user questions to heading text. Question-formatted headings (ending with “?”) are the primary signal AI systems use to identify which section answers a specific query.

    Why it matters

    H2 and H3 headings can be phrased as the natural-language question a user would ask, rather than as topic labels. The claim is that this increases the probability that the passage beneath the heading is matched to a fan-out sub-query and cited — over and above having descriptive headings at all.

    Evidence

    Question-form headings

    Headings as such are vendor-documented. Google states that pages should be ‘organized by paragraphs and sections, along with headings that provide a clear structure’. And Google’s own definition of query fan-out — ‘a set of concurrent, related queries generated by the model’ — supplies a plausible mechanism for why question-shaped subheads would match sub-queries. GEO-SFE measured macro-structure (heading architecture, target depth 3–5 levels) as 44.9% of a 17.3% citation gain (p<0.001) with a −3.5pp ablation penalty. Indig’s dataset found ‘78.4% of citations tied to questions came from headings’, consistent with H2s acting as prompts and following paragraphs as answers. Semrush’s 200k-keyword study confirms AI Overview queries skew to ‘how’/‘what’ questions (35% desktop, 32% mobile), so question-shaped demand is real.

    Limits

    No vendor documents question-form headings, and Google explicitly says ‘You don’t need to write in a specific way just for generative AI search.’ The 78.4% figure is a conditional proportion: of the citations that involved questions, most came from headings. It does not establish that converting a label heading to a question heading raises the citation rate, and the base rate is unstated. GEO-SFE tested heading depth and architecture, never question phrasing, so the controlled evidence does not cover this signal.

    C-SEO Bench found most authored content edits ineffective or actively harmful to ranking, and the GEO critical survey warns that ‘generic heuristics transfer poorly’ and ‘citation-oriented rewrites can impair retrieval.’ The vendor claims circulating in SEO blogs (‘question headings improve citation within 4–8 weeks’) trace to no measurable methodology. Distinguish two audits: ‘has a sane heading hierarchy’ is scorable; ‘headings are phrased as questions’ is not yet.
