The most common question we get in week one with a new dental client is some version of: “Do I still need SEO if we are doing AEO?” The answer is yes — and the answer to the inverse question (“do I still need AEO if I rank well on Google?”) is also yes. They are different optimizations of overlapping signals. Most agencies in 2026 either pretend they are the same thing or pretend AEO replaces SEO. Both takes are wrong.
Here is the honest technical comparison, drawn from roughly 200 dental practice audits and the AI citation patterns we have measured across the major engines.
The shared foundation
Roughly 60 percent of the work overlaps. Both SEO and AEO require:
- Crawlable HTML. Pages have to render server-side or hybrid. A pure JavaScript single-page app where content only appears after a user interaction is invisible to both Googlebot and the AI crawlers.
- Clean schema. JSON-LD for
Dentist,Physician,MedicalProcedure,FAQPage,AggregateRating. Google parses it for ranking. Bing parses it for its AI partners (which feeds ChatGPT and Copilot). Gemini reads it directly. - Google Business Profile. The local pack still matters for organic Google. GBP data also feeds Gemini and Apple Intelligence directly.
- Fast, mobile-friendly pages. Core Web Vitals, LCP under 2.5s, INP under 200ms. Same standard for both.
- Fresh content. Both engines reward recency. AI engines, especially Perplexity, are more aggressive about it than Google is.
- Real reviews on Google, Yelp, Healthgrades. AggregateRating signals are read by both classic SEO and every AI engine.
This shared foundation is why practices already doing competent SEO have a 30–40 point head start when they begin AEO work. It is also why we never recommend abandoning SEO to “go all-in on AEO” — you would be tearing down the bottom of the funnel.
Where the two diverge — content shape
This is the biggest delta. SEO and AEO want different content shapes on the same topic.
SEO-shaped content is keyword-organized. The page is built around a target keyword phrase: “dental implants Dallas,” “Invisalign cost Houston.” H1 and H2 contain the keyword variants. Internal links use the keyword as anchor text. The page reads top-down: hero, benefits, process, FAQ, CTA.
AEO-shaped content is citation-organized. The page is built around a set of specific patient questions that AI engines might quote in their answer. Each major H2 is phrased as a question. Each paragraph under the H2 is a quotable, self-contained answer of 60–120 words. Cost ranges are explicit, year-tagged. Comparisons are tabular. Credentials and review-dates are visible above the fold.
The trick is that you can do both on the same page. The best dental service pages we ship combine a SEO-shaped frame (target keyword in H1, internal link structure, full URL slug) with AEO-shaped body content (Q&A blocks, cost ranges, comparison tables, author byline, “medically reviewed by” stamp). That fusion approach is what dental agencies who are still selling 2018-era SEO have not figured out.
Where the two diverge — off-page signals
Classic SEO weighs backlinks. AEO weighs brand mentions. They sound similar; they are not.
A backlink is a hyperlink from another domain pointing to your page. Google still uses these — PageRank lives. The dental SEO ecosystem has spent 15 years building cottage industries around getting backlinks: directory submissions, guest posts, link rentals.
A brand mention is your practice name appearing in a trustworthy context, with or without a hyperlink. ChatGPT, Perplexity, and Gemini all weigh these heavily in the ranking layer. A name-drop in a Healthline procedure explainer, a Reddit thread, or a “Best of [City]” listicle is worth more for AEO than 50 directory backlinks.
The practical implication: if your existing SEO program has been built around backlink acquisition, it is probably not earning AEO points. You need to add a brand-mentions stream — PR pitches to Healthline / Verywell / Forbes Health editors, dental podcast guest appearances, Reddit presence, local listicle outreach, Wikipedia entity work.
Where the two diverge — engine targets
SEO has effectively two targets: Google (about 90 percent of US search market share) and Bing (about 7 percent). Everything else is a rounding error.
AEO has at least eight meaningful targets, each with different data pipelines:
- ChatGPT (about 60–65% of AI search referrals) — Foursquare + Bing Places + brand mentions
- Perplexity (about 8–10%) — its own crawler + Brave Search + Reddit-heavy
- Google AI Overviews (about 15–20%) — Google index + Gemini engine
- Google Gemini standalone (about 5–7%) — Google index, more GBP-weighted
- Microsoft Copilot (about 3–5%) — Bing index pure-play
- Claude.ai web search (about 2–4%) — Brave Search API + OpenStreetMap + Wikidata
- Meta AI (about 2–3%) — Bing + Facebook + Instagram business profiles
- Apple Intelligence and Siri (about 3–5%, rising fast) — Apple Maps + Apple Business Connect + ChatGPT extension
You optimize differently for each. A pure-Google SEO strategy will earn some AEO points (Google AI Overviews + Gemini) but leave the other 70 percent of AI traffic on the table.
When does SEO matter more, when does AEO matter more?
SEO still wins for high-intent local-pack queries. “Dentist near me,” “emergency dentist [city],” “[insurer] dentist accepting new patients” — these are queries where AI engines now actively defer to Google Maps and the local pack. Google deliberately suppressed AI Overviews on “near me” queries as of late 2025. If you live or die on Google Maps, classic local SEO is still the rent you pay.
AEO wins for procedure-research and cost-comparison queries. “How much do dental implants cost in 2026,” “Invisalign vs braces,” “is All-on-4 worth it,” “best Invisalign provider near me” — these are the queries that drive high-value consultations, and they trigger AI Overviews or full AI answers roughly 80–90 percent of the time. If your top procedure pages are not citation-shaped, you are losing the most valuable third of the funnel.
Brand defense is split. “Reviews of [your practice name]” — Google still owns this query. “What do people say about [your practice name]” asked into ChatGPT or Perplexity — AEO owns this query. You need both intact.
The agency reality — why most are bad at this
Most dental agencies in 2026 are still selling 2018-era SEO with a sprinkle of “AI.” They added a paragraph to their pitch deck about “we also optimize for AI Overviews,” they bolted a meta-description rewriter onto their content workflow, and they call it a day. Then they bill $3,000 a month for it.
The honest 2026 stack looks like:
- A weekly local SEO pass (GBP, citations, review responses)
- A monthly content production rhythm built around citation-shaped service pages
- A schema deployment and audit cycle
- A PR / brand-mentions stream (Healthline pitches, podcast guesting, Reddit presence)
- Per-engine AEO tracking (Otterly, manual ChatGPT testing, GSC + Bing Webmaster AI Performance report)
- A Foursquare + Bing Places + Apple Business Connect maintenance loop
That is a real program. It looks more like editorial publishing than 2018 SEO. And it cannot be done by a single junior SEO swapping out title tags.
The bottom line for dental practices
You need both. Practices that bet entirely on SEO will quietly lose ground to AI as it eats more queries. Practices that bet entirely on AEO will starve waiting for AI traffic to become primary. The right answer is a parallel program where the same content team writes service pages that work for both, the same technical team maintains schema and crawlability for both, and the same reporting layer tracks Google rankings and AI citations side by side.
The total work is roughly 30 percent more than a clean SEO program. The returns are roughly 2–3x because you start earning the high-converting AI traffic that previously went to your competitors by default.
Where to start
We run a free 50-point AEO audit that overlays your AEO and SEO state on the same page. You see exactly where your existing SEO work is paying AEO dividends, where the gaps are, and which fixes move both numbers at once. No call required to get the PDF.
Request the audit at thorli.com/free-audit. 48-hour turnaround. You keep the deliverable. If your existing agency is doing this work well, the audit will say so — we will not invent problems to win a deal. If they are not, you will at least know what to ask them at the next QBR.
