Foundational definitions

What is Answer Engine Optimization (AEO)?

When a patient asks ChatGPT "best orthopedic surgeon in Boston," is your practice among the sources it cites? With nearly 60% of US adults searching for health information online, and AI tools rapidly becoming part of that journey, practices that aren't optimized for answer engines are invisible to a growing segment of patients.

Entity SEO explained

When patients search for "orthopedic surgeon near me," Google isn't just matching keywords anymore – it's looking for known, trusted entities. If your practice isn't established as an entity in Google's Knowledge Graph, you're invisible to both traditional search and AI tools like ChatGPT.

E-E-A-T for healthcare websites

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness – the criteria Google uses to evaluate content quality. Healthcare websites fall under "Your Money or Your Life" (YMYL) categories, meaning Google holds medical content to the highest quality standards because inaccurate health information can directly harm people.

Knowledge graph optimization

Google's Knowledge Graph is a database of billions of entities and their relationships. When your practice is properly represented in the Knowledge Graph, you become more visible in search results, AI overviews, and knowledge panels.

Medical schema markup

Schema markup is a structured data vocabulary that helps search engines understand your content beyond the words on the page. For healthcare practices, medical schema types communicate your services, provider credentials, treatment details, and clinical expertise in a format that both search engines and AI systems can reliably parse and cite.

Local SEO for doctors

Local SEO focuses on improving visibility for location-based searches. For medical practices, this means appearing when patients search for "orthopedic surgeon near me" or "best dermatologist in ."

Healthcare structured data implementation guide

Structured data tells search engines exactly what your practice does, where it is, and who works there – in a language they can parse directly. For healthcare sites, proper JSON-LD implementation can unlock rich results, improve local visibility, and make your content citable by AI tools.

Medical schema markup: comprehensive guide

Medical schema markup uses Schema.org vocabulary to describe healthcare entities – practices, providers, conditions, and treatments – in a structured format that search engines and AI tools can parse. This guide covers every schema type relevant to healthcare with implementation details.

Understanding the mechanics

How it works

How AI search works

AI search tools like ChatGPT, Perplexity, and Google AI Overviews are changing how people find information. Understanding how these tools work is essential for ensuring your practice gets discovered and cited.

How Google ranks medical content

Google applies heightened scrutiny to medical content because it can significantly impact people's health, safety, or finances. Understanding how Google evaluates healthcare websites is essential for ranking well.

How patients search for doctors

Understanding how patients search for healthcare providers helps you meet them where they are. Patient search behavior has evolved significantly – with nearly 60% of US adults searching for health information online – driven by the rise of AI tools, mobile search, and changing expectations.

Zero-click search in healthcare

Zero-click searches occur when users get the information they need directly from the search results page without clicking through to any website. With 58.5% of US Google searches now ending without a click, healthcare practices face significant implications for visibility and patient acquisition.

Local pack optimization for healthcare

The local pack – the map and three business listings at the top of local search results – captures a disproportionate share of clicks for healthcare queries. Google determines local pack rankings using three primary factors: relevance, distance, and prominence.

Voice search optimization for healthcare

Voice searches are inherently conversational – patients ask "Hey Google, what's a good dermatologist near me?" rather than typing "dermatologist near me." This shift toward natural language queries changes how practices need to structure content for discovery.

How to get recommended by ChatGPT

There is no submission form to "get listed" in ChatGPT. AI recommendations are earned through the same signals that build authority across the web – structured data, consistent entity information, and authoritative content. For healthcare practices, this means optimizing the digital signals AI tools use to evaluate and recommend providers.

Understanding the differences

Comparisons

Entity SEO vs keyword SEO

SEO has evolved from matching keywords to understanding entities. While keywords still matter, modern search engines prioritize understanding what entities exist on your site and how they relate to searcher intent.

SEO vs AEO: what's the difference?

Your practice ranks on page one of Google, but when a patient asks ChatGPT for recommendations, you're nowhere to be found. Sound familiar? As AI-powered search transforms how patients find healthcare information, practices that only focus on traditional SEO are missing half the picture.

Traditional SEO vs entity-first SEO

For years, SEO meant targeting keywords – researching what patients search and optimizing pages to rank for those terms. But search engines have fundamentally changed. Google's Knowledge Graph now contains over 8 billion entities, and AI systems like ChatGPT retrieve information by understanding what entities exist, not just which keywords match. The practices still optimizing for keywords alone are increasingly invisible to both traditional search and AI.

Google AI Overviews for healthcare

Google AI Overviews (formerly Search Generative Experience) provide AI-generated summaries at the top of search results. For healthcare queries, these overviews significantly impact how patients discover and evaluate providers.

Industry considerations

Healthcare-specific

Healthcare marketing compliance

Healthcare marketing operates under strict regulatory requirements. Understanding compliance isn't just about avoiding penalties – it's about building trust with patients who expect their healthcare providers to operate ethically.

Patient reviews and reputation management

Patient reviews significantly influence both search rankings and patient decisions. Google explicitly states that "review count and review score factor into local search ranking," making online reputation management essential for attracting new patients while maintaining trust.

AEO for healthcare

Answer Engine Optimization (AEO) for healthcare is the practice of structuring your medical practice's online presence so that AI-powered tools – ChatGPT, Google AI Overviews, Perplexity, and others – cite, recommend, and surface your practice when patients ask health-related questions. As AI search tools handle an increasing share of patient research, the practices that appear in AI-generated responses gain a significant acquisition advantage over those that only optimize for traditional search rankings.

YMYL content guidelines for clinics

Google classifies healthcare content as "Your Money or Your Life" (YMYL) – content that can significantly impact a person's health, financial stability, or safety. For clinics, this means every page on your website is held to a higher quality standard than a typical business site.

Healthcare E-E-A-T checklist

E-E-A-T – Experience, Expertise, Authoritativeness, and Trustworthiness – is how Google evaluates whether your healthcare content deserves to rank. This checklist translates abstract quality guidelines into concrete actions you can implement on your clinic website today.

AEO for healthcare patient acquisition

When a patient asks ChatGPT "best physical therapist in Austin," the practices that appear in the response are capturing a new patient acquisition channel. Answer Engine Optimization (AEO) focuses on making your practice citable by AI tools – turning AI mentions into booked appointments.
