Why ChatGPT cites one page and ignores another: GEO optimisation

A page can appear in ChatGPT’s research set and still never get cited. That is the useful, slightly uncomfortable lesson from Ahrefs’ April 2026 study of 1.4 million ChatGPT prompts.

For SMEs, this changes the practical meaning of generative engine optimisation. It is not enough to publish a good article and hope an AI answer includes it. Your page has to be selected at several points: it has to be discoverable, retrieved, judged relevant, opened, and then considered worth citing.

Ahrefs found that ChatGPT retrieved many URLs that did not make it into the final answer. In its dataset, ChatGPT cited roughly half of the URLs it retrieved. That gap is where GEO work now needs to focus.

For a broader primer, Kahunam’s guide to generative engine optimisation explains how AI answer visibility sits alongside traditional SEO.

What ChatGPT appears to look at before it cites

The important point is that an AI system may evaluate a page before it reads the full page. Ahrefs describes a retrieval layer where candidate results include fields such as title, URL, snippet or summary, and source type.

That means your title and URL are not just SEO housekeeping. They may be part of the first filter.

For a small business, the checklist is straightforward:

• Write titles that answer the specific question, not just the broad topic.
• Use clear, human-readable URL slugs.
• Keep pages focused on one intent rather than mixing several jobs into one article.
• Make the useful answer visible early on the page.
• Keep conventional search performance healthy, because ChatGPT’s general search source was a major route to citations in the Ahrefs study.

None of this replaces SEO. It tightens it.

Optimise for the sub-questions, not just the main query

A customer might ask ChatGPT, ‘Which CRM is best for a small estate agency?’ The AI may break that into smaller questions: pricing, integrations, reporting, data import, support, and whether it works for UK businesses.

If your article title only says ‘Best CRM software’, it may be too vague. If your page answers the specific sub-questions clearly, it has a better chance of matching the AI’s internal research path.

This is where SMEs can compete. You do not need to out-publish larger brands on every topic. You need pages that are specific, credible, and easy to match to the questions buyers actually ask.

What to stop wasting time on

Do not treat GEO as a new bag of tricks. The study does not prove that adding an AI-friendly badge, repeating ‘ChatGPT’, or stuffing a page with extra schema will make it citable.

The stronger lesson is simpler: if your title, URL, and page content do not line up with the user’s real question, the page may be ignored even if it was retrieved.

A sensible GEO review starts with your most commercially important pages:

1. Pick one buyer question per page.
2. Rewrite the title so it reflects that question in plain English.
3. Check whether the URL slug is readable without context.
4. Add a short, direct answer near the top.
5. Support the answer with evidence, examples, pricing notes, or process detail.
6. Remove sections that dilute the page’s purpose.

The practical takeaway

GEO is not magic. It is disciplined page clarity.

If ChatGPT is choosing between two pages, the clearer page has an advantage: a title that matches the question, a URL that explains itself, and content that answers the likely follow-up questions. That is useful work whether the visitor comes from Google, an AI answer, or a human referral.
