THE SHORT ANSWER
Question headings help for a specific mechanical reason: when a page is split at heading boundaries, the heading becomes the first line of the fragment, and a heading phrased as a question matches conversational queries far more directly than a noun phrase does. The effect is real and modest. Applying it to every heading on every page makes the writing repetitive and inflates length, so mix question headings with concretely descriptive ones.
This is one of the few GEO tactics where the mechanism is both easy to state and easy to verify for yourself. Heading-aware chunking makes the heading the opening line of the retrieved fragment, and an opening line that restates the user's question is about as strong a relevance signal as a passage can carry on its own.
What follows from that mechanism is narrower than the advice usually given, and the narrowing is the useful part. Question headings help where the section underneath genuinely answers a question somebody actually asks. Everywhere else they are decoration, and decoration carries a real cost in a system that reads your page as a series of disconnected fragments.
The numbers, at a glance
The mechanism: under heading-aware chunking the heading becomes the fragment's first line, which carries outsized weight
Where it helps most: sections answering a question a buyer would actually type or say aloud
Where it backfires: pages where every heading is a question, which reads as templated and pads the page
A workable ratio: roughly half question-shaped, half concretely descriptive, decided section by section
Why the heading does more work than its size suggests
In a document split on H2 and H3 boundaries, the heading is not merely a label on the fragment. It is text inside it, positioned first, which means it contributes to the embedding and sits where reranking models weight most heavily. A heading reading How much does a heat pump cost in a 1930s house is close in meaning to the query that produced it in a way that a heading reading Cost considerations simply is not.
There is a secondary benefit worth noting. Question headings force you to write an answer underneath, because the structure makes an evasive paragraph obviously evasive. Half the value of the tactic is the editorial discipline it imposes rather than the retrieval signal itself.
When a descriptive heading is the better choice
When the section is a process. A heading like The five stages of a roof replacement describes what follows more usefully than turning it into a question.
When the section is a list of definitions. Naming the set beats asking about it.
When nobody asks that question. Inventing a question to fit a heading produces the artificial phrasing everyone recognises as SEO filler.
When the page already has four question headings. Past that point they stop being distinctive and start reading as a template.
When the answer is a number. A heading that states the finding, such as Typical wait times are six to ten weeks, is even more extractable than the question form.
How to phrase the question so it actually matches
Use the buyer's vocabulary, not the industry's. Somebody types what does a new boiler cost, not boiler replacement investment considerations. Keep it to the length a person would actually speak, since voice and conversational queries skew towards natural phrasing and away from compressed keyword strings.
Include the qualifier that makes the question specific. How long does installation take is a question thousands of pages answer badly. How long does a heat pump installation take in an occupied house is a question with a much smaller set of competing passages and a much more useful answer underneath it. The qualifier is where the retrieval advantage actually comes from.
The hygiene that has to be in place first
None of this matters if the heading structure is broken underneath. One H1 per page carrying the main subject, H2s for the major sections, H3s only where they nest inside an H2, and no level skipped for visual reasons. Structure-aware chunkers rely on that hierarchy to decide where a section starts and ends, and a page that jumps from H1 to H4 because of a stylesheet gives them nothing to work with.
Also worth checking: headings implemented as styled paragraphs rather than real heading elements, which happens constantly in visual page builders. Those pages look correctly structured to a human and appear completely flat to a parser, which removes every advantage this page describes.
Fixing headings on an existing page
Confirm each heading is a real heading element rather than a bold paragraph styled to look like one.
Check the hierarchy runs H1 then H2 then H3 with no skipped levels.
Rewrite the headings covering genuine buyer questions into the buyer's own phrasing.
Leave process and definition sections as descriptive headings rather than forcing a question.
Add the specific qualifier to each question heading so it competes in a smaller field.

Frequently asked questions
Should every heading on the page be a question?
No. Beyond about four, the page reads as templated and the individual headings stop standing out from each other. Use the question form where a buyer genuinely asks that question and a descriptive form where the section is a process, a list or a set of definitions.
Do question headings help classic search rankings too?
They help indirectly by matching long-tail conversational queries and by improving the odds of a featured snippet. The direct ranking effect is small. Treat the retrieval benefit as the reason and any snippet gain as a secondary return on the same work.
Does the answer need to come immediately after the heading?
Yes, and this is where most pages waste the tactic. If the paragraph under a question heading opens with background before answering, the fragment leads with a strong signal and follows it with nothing. Answer in the first sentence, then qualify.
What about phrasing headings as statements of the answer?
Often the strongest option when the answer is a specific finding. A heading stating the conclusion is highly extractable and reads well. The trade-off is that it matches the question less literally, so alternate the two forms across the page rather than committing to one.
