AEO (answer engine optimization) is the work of making your brand the one that AI answer engines, such as ChatGPT, Google AI Overviews and AI Mode, Gemini, Perplexity and Claude, name, cite and recommend when people ask a question. In healthcare marketing, it means being the practice, clinic or health brand an AI assistant recommends when a patient asks "who is the best pediatric dentist near me" or "which telehealth services treat acne," and making sure what it says about you is right. Curve Compliance helps healthcare brands with this. AI Visibility is a feature in Curve Compliance, and Curve also offers it as a managed service. Curve AEO is the managed service, with a team that handles the strategy and execution for you.

What AEO means
AEO stands for answer engine optimization. An answer engine is any tool that replies to a question with a written answer instead of a list of links. Classic SEO works to rank a page on a results page; AEO works to get your brand into the answer itself, ideally named, described accurately and linked as a source.
Google uses the same terms. Its guide for site owners says AEO and GEO (generative engine optimization) "are both terms you may see used to describe work specifically focused on improving visibility in AI search experiences" (Google). Outside marketing, AEO has other meanings, such as the EU's customs program for trusted traders (European Commission). In search and healthcare marketing, it means answer engine optimization.
The answer engines patients use
Answer engines now reach billions of people, and many of them bring health questions.
| Answer engine | Scale | Source |
|---|---|---|
| ChatGPT | More than 1 billion weekly active users (August 2026) | OpenAI |
| ChatGPT, health | More than 300 million people a week ask health-related questions (July 2026) | OpenAI |
| Google AI Overviews | Over 2.5 billion monthly active users (May 2026) | |
| Google AI Mode | Surpassed 1 billion monthly active users (May 2026) | |
| Gemini app | One billion users (October 2026) | |
| Google Search, health | More than a billion health questions every day (March 2026) | |
| Microsoft Copilot, health | Finding nearby providers, clinics or specialists was 43.1% of healthcare navigation conversations (January 2026 sample) | Microsoft |
These are company figures, global and not independently audited, but the direction is clear. OpenAI also said in January 2026 that "More than 40 million turn to ChatGPT every day with healthcare questions" (OpenAI).
Why AEO matters in healthcare marketing
Patients bring health questions to AI, and some of those questions are about where to get care. KFF found 32% of U.S. adults used AI for health information and advice in the past year, similar to social media (29%) but well behind doctors (80%) and internet search engines (68%) (KFF). Pew found 34% of U.S. adults use AI chatbots for at least one of eight health or medical reasons (Pew Research Center).
Choosing a provider is part of it. In rater8's April 2026 survey, 47% of patients said they had used an AI tool to research healthcare providers, up from 31% in 2025 (rater8). See how patients use ChatGPT to find a doctor for more on that journey.
What it means for you: when a patient asks an assistant for a recommendation, the answer names a few brands. AEO is how you work to be one of them.
How answer engines decide what to say
Most answer engines combine what the model already knows with a live web search. Google describes its approach as retrieval-augmented generation, "also known as grounding", which relies "on our core Search ranking systems to retrieve relevant, up-to-date web pages from our Search index." It also uses query fan-out: "A set of concurrent, related queries generated by the model to request more information" (Google). Google says AI Overviews are shown only when its systems determine they add to classic Search, "and as such, often don't trigger" (Google).
ChatGPT does not always search. Semrush found ChatGPT enabled web search on 34.5% of queries as of February 2026, "meaning most responses still rely on training data alone" (Semrush). So AEO works on two fronts: being present and accurate across the web the models learn from, and being the page live search finds and cites.
Which pages get cited is its own question. Ahrefs compared the links four AI assistants cited for 15,000 prompts with Google's results and found that, on average, only 12% ranked in Google's top 10 for the same prompt (Ahrefs). In health care, Conductor found mayoclinic.org (6.58%) and clevelandclinic.org (4.90%) earned the largest shares of AI citations in health care equipment and services (Conductor). For more, see where AI gets healthcare answers and query fan-out in healthcare.
Content choices matter too. In the GEO study presented at KDD, the best methods, citing sources, adding quotations and adding statistics, improved a page's visibility in AI-generated answers by 30% to 40% on the researchers' benchmark, and by up to 37% in a test on Perplexity, while keyword stuffing offered little to no improvement (Aggarwal et al.).
What AEO work involves
An AEO program for a healthcare brand usually covers six things:
- The questions. The questions patients ask at each stage, by service line and area.
- The answers today. How each assistant answers them, who it names and which sources it cites.
- Technical access. Pages that search crawlers can reach, index and read as text.
- Content. Clinician-approved pages that answer those questions directly, with sources and data.
- Facts. Correct hours, addresses, insurance and services on your site and the listings AI reads.
- Results. Visibility over time, visits from AI assistants, and the bookings they bring.
Our AEO strategy guide turns these into a step-by-step plan, and AEO tracking covers the measurement.
AEO, SEO and GEO
AEO builds on SEO rather than replacing it. Google says that from its side, "optimizing for generative AI search is optimizing for the search experience, and thus still SEO" (Google). The difference is the goal: SEO aims for a ranked page and a click, AEO aims to be the brand inside the answer. GEO is a close cousin focused on generative AI answers. See AEO vs SEO for healthcare and AEO vs GEO vs SEO.
Why AEO is different in healthcare
Health answers carry more weight, and patients know AI can be wrong. Among recent AI health users, only 4% strongly trust the accuracy of AI-generated health information, according to West Health-Gallup (Gallup). KFF found 44% of U.S. adults are not too or not at all confident they can tell whether health information from AI chatbots is true or false (KFF).
Yet many act on what they read. Of the patients in rater8's survey who had used AI to research providers, 66% said they had seen wrong provider details from an AI tool, and 60% said they trusted the summary they got without checking it (rater8).
That shapes AEO in three ways. Accuracy comes first, so wrong hours or insurance get fixed before anything else. Medical content needs a clinician to approve it before it goes live. And measurement has to keep patient information out of the questions you track and the tools you use. See what to do when AI is wrong about your practice.
What This Looks Like in Practice
In one AI Visibility program we've run, for a HIPAA-focused healthcare software brand, Curve's team tracked the questions buyers ask AI assistants, found where competitors were named and the brand wasn't, and published pages to close those gaps. About five weeks in:
- AI assistants named or cited the brand in 53% of their answers to its 40 core buyer questions (104 of 196), across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity and Claude.
- Across 184 real buyer questions and 912 AI answers, its site was cited in 236 answers, more than any competitor's and more than 2.5 times as many as the nearest one (89).
- 47 of the new pages were already cited by AI assistants within six days of going live.
- One new page brought in more than half of the brand's unpaid ChatGPT visits in its first week.
