A buyer asks ChatGPT, Gemini or Google which dealer to visit. The answer names two or three stores. If yours is not one of them, that buyer never sees your name. Our job is to get your store named, and to show the result where you already look: leads in your GA4.

Three words do all the work on this page. If you have never had to think about AI search, these are the only ones you need.
Two labels you will hear in sales pitches: AEO is the work of getting cited. GEO is the work of getting named.
Nobody had published which dealership pages AI engines cite, so we ran the study: the best-reviewed franchise dealer for each brand in each state, asked about across Google AI Overview, Google AI Mode, ChatGPT and Gemini.

21.1% of a dealership's answer pages were cited by an AI engine, against 0.8% of its inventory pages. Answer pages are guides, comparisons and FAQs; the study calls them editorial pages. Inventory is about three quarters of a typical dealer website.
89%
Of the 328 dealerships publishing at least ten pages of each type, 291 had a higher citation rate on answer pages than on inventory.

Technical readiness, Google star rating, review volume and website platform predicted nothing. 97.9% of the stores we audited already pass the technical checks, so passing them cannot explain who gets cited. The link with answer pages was moderate: a correlation of +0.36.
98% / 6%
Google AI Overview cites a source in 98% of answers where a dealership appears, and names the dealership in 6%. Gemini does close to the reverse: 61% cited, 51% named. One blended score hides which you are getting.
The study measures association, not causation, and the sample is review leaders by design (median 4.7 stars). The method, the confidence intervals and three withdrawn findings are published with it.

Read the case studyThey are names for what good SEO earns in AI search, not separate products. Google says as much: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary."
Google Search Central, AI features and your websiteAEO is writing your pages so an AI engine can use them as the source of its answer. When Google's AI Overview answers "what happens at the end of a Honda lease?" and links to your page, that is AEO working.
AEO in the glossaryGEO is getting your dealership named in the answer a buyer reads. When a shopper asks Gemini or ChatGPT which Toyota dealer to trust and the reply says your store's name, that is GEO working.

An assistant cannot quote a page it cannot reach, and Google cannot quote an answer nobody wrote down.
Answer the question first, give facts a reader can check, name the models and the town. A page written that way works for SEO, AEO and GEO at once.

Each of these is something our own study argues against, including things agencies like ours sell.
Ask any agency how it handles the SEO underneath before it sells you AEO or GEO. If your pages are not found and ranking, AI has nothing of yours to quote.
Almost every dealership already passes the technical checks for Google's AI features. Passing them is maintenance. It did not predict who gets cited.
Vehicle listings are most of a dealer website and are almost never cited. Keep them fast and accurate for the buyer who is ready to act. Visibility comes from answer pages.
A footnote on Google and your name written by Gemini are different results. Ask for cited and named separately, engine by engine, and compared with your competitors.
Five prompts swing wildly from month to month. AI visibility needs a large, fixed set of buyer questions, asked the same way every month.
Volume tracked with citation, so plenty of people will pull that lever with machine-written pages. Google's guidance is to publish what others couldn't. Publish more, and publish what only your store could have written.

new-vehicle buyers used an AI site such as ChatGPT, or an AI-generated overview, while shopping. Across all buyers it was 19%, in the first year Cox tracked it.

AI search optimization is the work of getting a dealership cited and named in the answers AI engines give car buyers: Google's AI Overviews and AI Mode, ChatGPT, Gemini and Perplexity. It combines AEO (being used as the source of an answer) and GEO (being named in the answer), and both are built on pages that are already found and ranking in Google.
Publishing answers to the questions buyers ask before they shop. In the A3 Brands Dealership AI Search Study of 661 US franchise dealerships, an answer page was 27 times more likely to be cited by an AI engine than a vehicle listing: 21.1% of answer pages were cited, against 0.8% of inventory pages. How many answer pages a store published was the only thing that predicted citation. Technical readiness, star rating, review volume and website platform did not.
AEO is about being cited: the engine uses your page as a source, often as a footnote or link. GEO is about being named: your dealership's name appears in the text the buyer reads. The engines treat the two very differently. In the A3 Brands study, Google AI Overview cited a source in 98% of answers where a dealership appeared and named the dealership in 6%. Gemini cited in 61% and named in 51%. That is why we count them separately.
No. AI SEO, ChatGPT SEO, AEO and GEO are different names for the same work: getting a car dealership cited and named in AI answers. Agencies use whichever label sells. What matters is whether the work produces answer pages that rank, because those are the pages AI engines cite.
Your SEO is where they start. What changes is which pages do the work: pages that answer buyer questions get cited, and inventory pages almost never do. A store can rank well for its inventory and still be missing from AI answers because it never published the answers.
Not in our study. Neither star rating nor review volume predicted citation. Two cautions: the sample was review leaders (median 4.7 stars), so this says nothing about low-rated stores, and reviews still decide which of two named dealerships a buyer picks.
Not for Google. Google says you don't need new machine-readable files, AI text files or special schema.org markup to appear in its AI features. Structured data is still worth having for rich results, and other AI systems may read llms.txt, but neither is what gets a dealership cited.
Months, not days. Engines cite pages that are already indexed and ranking, so the timeline follows your SEO: technical fixes take effect as pages are recrawled, and citations build as answer pages are published and start to rank. We report cited and named counts every month so you can see the movement.
A3 Brands' programs start at $2,499 per month, with no setup fees and no long-term contract. SEO, AEO and GEO are one program, because they are one body of work.
