AEO vs GEO vs AI SEO: What Dental Practices Actually Need to Know

AEO (Answer Engine Optimization), GEO (Generative Engine Optimization), and AI SEO all describe the same goal: making your practice the answer AI tools give when a patient asks for a dentist. The names differ because agencies coined them separately; the work overlaps almost completely with strong SEO. Google’s own guidance for its AI features (AI Overviews and AI Mode) says the path in is still SEO. What matters is not which acronym your agency uses. It is whether the work behind the acronym gets your practice recommended, and whether anyone can show you it booked a patient.

Key takeaways

• AEO, GEO, and AI SEO are marketing labels for overlapping work, not three separate services. If a proposal prices them as separate line items, ask what is actually different in the deliverables.
• Google’s public guidance for its own AI features is blunt: there is no special AI optimization trick. Helpful, crawlable, well-structured content is what gets cited (Google Search CentralThis link opens a new tab to Google Developers website, accessed June 2026). ChatGPT and Perplexity publish no equivalent playbook, which is where the verification work comes in.
• The search demand is real: “AEO vs GEO” grew from near zero to about 880 US searches a month in the past year (SemrushThis link opens a new tab to Semrush website, July 2026). Practice owners are being pitched these terms, then Googling them.
• AI answers pull heavily from pages that already earn trust. In Ahrefs’ study of 1.9M AI Overview citations, 86% came from domains in Google’s top 100 for the query (AhrefsThis link opens a new tab to Ahrefs website, July 2025).
• The two shifts worth acting on are discipline, not new invoices: reviews now count on every platform an AI reads, not just Google, and a consistent name, address, and phone number everywhere matters again.
• The acronym does not matter to a patient. The short list of names an AI reads out does.

Where did these three acronyms come from?

Two years ago, none of these terms appeared in a dental marketing proposal. Now most proposals carry at least one. Here is the plain-English version of each.

AEO, Answer Engine Optimization, is the oldest of the three. It means structuring content so that answer engines, which includes Google’s AI OverviewsThis link leads to a blog post about AI overviews for dentists and voice assistants, can lift your answer directly. Question-format headings, direct first-paragraph answers, FAQ sections.

GEO, Generative Engine Optimization, came out of a 2023 academic paper and got adopted by agencies as the ChatGPT-era term. It means influencing what generative AI tools like ChatGPT and Gemini say when they compose an answer, mostly by being present in the sources those tools retrieve and cite.

AI SEO is the catch-all. Some agencies use it to mean optimizing FOR AI engines; others use it to mean doing SEO WITH AI tools. When you see it in a proposal, ask which one they mean. The two are completely different services.

What is the difference between AEO, GEO, and AI SEO?

Feature	AEO	GEO	AI SEO
Stands for	Answer Engine Optimization	Generative Engine Optimization	Not standardized
Aimed at	AI Overviews, voice, featured answers	ChatGPT, Gemini, Perplexity answers	Depends who is selling it
Core work	Answer-shaped pages, FAQs, structure	Citable sources, authority, mentions	Ask the vendor
Overlap with SEO	Nearly total	Very high	Total, or unrelated
What is genuinely new	Formatting discipline	Tracking where AI mentions you	Usually nothing

The honest summary of that table: the middle rows are all things a strong dental SEOThis link leads to Dental SEO page program has done for years. Clear pages that answer real patient questions, a Google Business Profile that is complete and activeThis link leads to a blog post about dental GBP AI checklist, reviews that mention specific treatments, and a site that loads and crawls cleanly. The acronyms renamed the work; they did not replace it.

Will the overlap last forever? Probably not. The disciplines will branch as AI search matures, and we read the AI visibility research daily so we catch the split when it starts. It has not started yet. For now, there is one playbook, and the section below is the part of it that decides whether AI says your name.

Why are there three names for the same work?

Because new names sell. When a category shifts, and AI search is a real shift, the fastest way for an agency to look current is to coin or adopt a term the client has not heard before. The term creates a knowledge gap, the gap creates anxiety, and the anxiety creates a line item.

We watched this happen inside our own sales conversations this spring. Prospects started arriving with proposals from other agencies quoting separate AEO packages on top of existing SEO retainers. When our team compared the deliverables line by line, the AEO scope was largely the SEO scope with new labels.

That is not a reason to dismiss the shift. Patients genuinely do ask ChatGPT and Google’s AI for dentist recommendations. It is a reason to interrogate the invoice.

Cory Roletto: “For its own AI surfaces, Google has already answered this: AI Overviews and AI Mode run on the same index and the same signals, so the path in is still SEO. There is no hidden AI-only schema, no AEO switch to flip, and anyone selling you a brand-new secret tactic for AI visibility is lying to you. When an agency prices the acronym as a separate service, you’re usually paying twice for the same fundamentals.”

What actually determines whether AI recommends your practice?

Strip away the labels and the mechanics are measurable. Four things carry most of the weight.

First, your existing search authority, with one big caveat. Ahrefs analyzed 1.9 million AI Overview citations and found 86% came from domains already in Google’s top 100 for the query, and 76% from the top 10 (AhrefsThis link opens a new tab to Ahrefs website, July 2025). Google’s AI answer is largely assembled from pages Google already trusts. But the conversational tools roam wider: in a separate Ahrefs study, more than 80% of ChatGPT, Gemini, and Copilot citations did not rank in Google’s top 10 for the same query (AhrefsThis link opens a new tab to Ahrefs website, August 2025). Rank still pays on Google’s surfaces; on the chat engines it helps but guarantees nothing, which is why you verify each engine separately.

Second, retrieval position for conversational tools. For ChatGPT-style answers, being the first retrieved result matters enormously: pages in the top retrieval slot were cited 58.4% of the time versus 14.2% at position ten (AirOps analysisThis link opens a new tab to AirOps website, 2026). Different engines, same lesson: the top of the pile gets quoted.

Third, your Google Business Profile, your reviews, and your consistency. Google’s AI surfaces lean on the same local SEO signalsThis link leads to a blog post about local SEO as the map pack: categories, services, hours, photos, and review text. A review that lists specifics about the office and its services is machine-readable evidence of what you do. Fifty reviews that are generic, such as “this is a great office,” are not. Two things have genuinely shifted here, and both are discipline rather than new spend. Reviews now count everywhere an AI reads, not only on Google: Yelp, Facebook, and the rest of the profiles a conversational engine can pull into an answer, which is why a steady system for earning reviewsThis link leads to a blog post about getting Google reviews beats chasing any single platform’s count. And consistency is back: one name, one address, one phone number, identical everywhere your practice appears. Real photography and unique videoThis link leads to a blog post about real photography bringing reviews, on the site, your social media profiles, and your Google Business Profile, work the same way a specific review does: engines treat them as evidence, and stock assets as filler.

Fourth, pages that answer the actual question. AI Overviews appeared on 15.69% of queries in Semrush’s most recent large-scale study, and far more often on question-format searches (SemrushThis link opens a new tab to Semrush website, December 2025). Service pages that directly answer “does a dental implant hurt” and “what does it cost” get lifted; pages that describe your commitment to excellence get skipped. One cheap upgrade almost no dental website makes: write in the first person. Most practice sites were written in corporate third person, because that is what templates produce. Engines scoring for first-hand expertise, authority, and trustThis link leads to a blog post about building expertise, authority and trust reward a service page where the dentist explains how they actually do the procedure, in their own voice.

Note what is missing from that list: any acronym-specific tactic. Perplexity leans more on community sources and industry publications than the others, which is worth knowing for the long tail, but it does not change the work either.

Cory Roletto: “Reviews used to mean Google reviews. For AI visibility, it is reviews everywhere: Google, Yelp, ZocDoc, Facebook, all of it. And citation consistency matters again. Google spent years learning to forgive a practice with three different tracking numbers; the AI engines have not. So we keep one phone number consistent across the directories and profiles the engines read, and we scope tracking numbers far more narrowly than we did two years ago. None of that is a new service. It is the old discipline with new stakes.”

What we would not do

• We would not buy AEO and SEO as separate line items without a deliverable-by-deliverable comparison showing what is actually different. Usually the answer is a formatting pass and a tracking report.
• We would not pay for an AI ranking guarantee. AI answers are composed per query and per user; two patients can get different answers to the same question. Nobody can guarantee a slot in an answer that is generated fresh each time.
• We would not panic-spend. Clickstream panel data still put Google at roughly 73.7% of US desktop search activity, against about 3.2% for AI tools (SparkToro/DatosThis link opens a new tab to Sparktoro website, Q4 2025). AI search is growing and worth winning, but it is an addition to the SEO fundamentals that hold up under AI searchThis link leads to a blog post about beating AI dental SEO, not a replacement for them.
• We would not go fully automated either. The cheap end of this market is AI-generated content at scale with no human review. In a health category, where trust signals and accuracy carry extra weight, that is how practices end up with pages an engine will not cite and a patient will not read.

Shannon Mackey, CEO: “Everything on that list gets sold by pointing at the same fear: that AI is passing your practice by. But the patient on the other side of this has not changed. She is still a person deciding who to trust with her health. She asks, she hears a few names, and she books the one that feels real. Be one of the names, then be the one worth choosing.”

What should you do this quarter?

Three checks, no new budget required.

1. Ask the engines what patients hear. Ask ChatGPT and Google (in AI Mode) “best [your top service] dentist in [your city].” Note who gets named. Do it for your three highest-value services.
2. Read your proposals with the table above. If AEO, GEO, or AI SEO appears as a priced item, ask the vendor to name one deliverable in that item that is not already standard SEO scope. Their answers will tell you everything. It is the same discipline as the ten questions we tell owners to ask before choosing a website and SEO companyThis link leads to a blog post about choosing a website company.
3. Check one measurement question. Whoever runs your marketing: can they show which channel, including AI answers, drove your last ten new patients? If nobody can, the acronym debate is a distraction from the real gap.

FAQ

Is AEO different from SEO?
The techniques overlap almost entirely. AEO emphasizes answer-shaped formatting (question headings, direct answers, FAQs) so engines can lift your content. Google’s guidance for its own AI features states that the path in is still SEO. Treat AEO as a discipline inside SEO, not a second service.

Do I need GEO if I already rank well on Google?
Mostly, ranking is the prerequisite. Most AI citations come from already-trusted pages. What a good program adds is verification: checking what ChatGPT, Gemini, and Perplexity actually say about your practice, since AI mentions do not always mirror rankings.

Does schema markup still matter for AI search?
Yes, as standard SEO scope, not as an AI upsell. Schema is the structured labeling that has produced rich results for a decade, and rich results are machine-readable evidence engines can lift. Parts of the industry argue schema has no effect on AI answers; what is certain is that no secret AI-only schema exists, and Google says its AI features need no special markup beyond normal structured data. We keep shipping schema on every page because it earns rich results today and costs nothing extra inside a strong SEO program.

How do I know if AI search is sending me patients?
Directly attributing an AI answer to a booking is still hard; Google’s new Search Console generative-AI report (announced June 2026, rolling out UK-first) shows how often you appear in AI answers (Google calls these impressions), not who booked. The practical method is asking every new patient how they found you, tracking it in your practice management system, and watching the “asked an AI” answers grow. We walk through the five metrics that measure dental marketing ROI after the AI shiftThis link leads to a blog post about measuring the dental marketing AI shift. Measurement is half of this work that most agencies skip.

How much should a dental practice pay for AEO?
As a separate product: nothing, until someone shows you deliverables that are not already in your SEO scope. As part of a strong SEO program that includes answer-shaped content, GBP and review discipline, and AI-mention tracking, it is included in the work you are already buying.
