Intro
Ask ChatGPT for the best tool, product or agency in almost any category, then look at the sources it shows. You will see best-of lists, review sites, forum threads and news articles. You will rarely see the websites of the brands it recommends.
That is the part of AI search most SEO plans miss. The work that gets a brand named in an AI answer happens mostly on other people's pages.
How little of the answer comes from your own site
We track AI answers for client brands every day. For one study we took 90 days of citations in three unrelated categories, auto insurance, beauty and cannabis retail, and sorted the cited domains by type.
The brand's own website was 2 to 6 percent of what the engines cited. Third-party editorial, community and reference sites made up 26 to 59 percent.
The mix also changed a lot by category. In beauty, editorial sites led with about 41 percent of citations. In cannabis retail, corporate sites led with about 66 percent. So there is no single list of sites that matter for everyone. You have to look at your own category.
Two outside numbers point the same way. Ahrefs found that about 43.8 percent of the pages ChatGPT cites are listicles: "best X" and "top 10 Y" articles. And SparkToro's 2026 clickstream data puts US zero-click searches at about 68 percent, so a growing share of research ends without a visit to anyone's site.
Why the engines behave this way
When someone asks for a recommendation, an AI assistant is not ranking pages. It is writing an answer and looking for sources that compare options. A brand's homepage cannot compare itself fairly with competitors, so it is a weak source for that job. A roundup or a review can.
The engines also differ. In our experience, Google's AI Overviews draws heavily on pages that already rank in classic search, so normal SEO still pays off there. ChatGPT and Perplexity lean harder on the third-party pages they retrieve at the moment of the question.

Prompt wording matters more than most people expect. For one DTC supplement client, ChatGPT ranked the brand first for "what is the best creatine gummy", but for "best creatine gummies" it named the brand without putting it first. Same product, same week, a small change in the question.
What to do about it
1. Build a prompt list, not just a keyword list. Write down the questions your buyers ask an AI assistant: best for a use case, alternatives to a competitor, is this brand worth it. Start with the questions your sales team hears on calls. Twenty is enough to begin.
2. Record the sources, not just the mentions. Run each prompt through ChatGPT, Gemini and Perplexity and note every source URL the answer cites. That list tells you exactly which pages decide the answer in your category. It is a better link plan than any domain authority export.
3. Get onto those pages. Most of them will be roundups, reviews and comparisons. Pitch the authors with a short, specific case and proof they can check. Some publishers sell placements; if you buy one, check that the engines actually cite the site first.
4. Make your own pages easy to quote. Put a direct answer near the top. Use clear comparison tables. Add Organization, Product and FAQ schema. A model lifts passages, so each section should make sense on its own.
5. Check that AI crawlers can get in. Look at your robots.txt and CDN settings for GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot and Google-Extended. We have seen sites block every one of them by accident and only find out when they wonder why they never appear.
6. Measure over weeks, not days. AI answers change between runs. Compare four-week windows and treat a one-week jump as noise until it holds. We learned this on our own site, when a burst of ChatGPT traffic that looked like a trend turned out to be a single unusual week.
Where traditional SEO fits
None of this replaces SEO. The pages that rank in Google feed AI Overviews, and a site that crawlers cannot read will not be cited anywhere. What changes is where the extra effort goes. Once the technical base is sound, most of the remaining gains in AI search come from being present on the pages the engines already trust.
If you would rather hand this to a specialist, we keep a comparison of the best AEO agencies, with our own name on it and a note on where others are the better fit.
