When someone asks ChatGPT “best dentist in Naperville” or tells Gemini “find me a personal injury lawyer near me,” the AI does not return a list of links. It gives a direct recommendation. One or two names. That is it.
Answer Engine Optimization (AEO) is the practice of making your business visible to these AI-powered answer engines so they recommend you when potential clients ask for help.
Why AEO matters now
According to BrightLocal's 2026 Local Consumer Review Survey, 45% of consumers now use AI tools to find local businesses - up from just 6% the year before. That is the fastest consumer behavior shift since mobile.
Meanwhile, ChatGPT has grown to over 800 million weekly active users (OpenAI, October 2025). Google's share of US search fell to 73.7% when AI and alternative platforms are included, according to SparkToro/Datos' Q4 2025 research.
The direction is clear. A growing share of your potential clients are asking AI instead of Googling. If your business is not in those AI answers, you are invisible to them.
How AEO differs from SEO
SEO optimizes for Google's ranking algorithm - backlinks, keywords, page speed. AEO optimizes for a completely different system. AI engines pull from structured data, review sentiment, directory consistency, and entity authority to decide who to recommend.
A business can rank #1 on Google and still be completely absent from ChatGPT's recommendations. The signals are different. The optimization is different. You need both.
The four signals AI engines use
Based on our analysis of thousands of AI recommendations across ChatGPT, Gemini, Claude, and Perplexity, four signals consistently determine who gets recommended:
- Structured data - JSON-LD schema markup (LocalBusiness, FAQ, Service) that tells AI exactly what you do and where you are.
- Review sentiment - Volume, recency, and specificity of reviews across Google, Yelp, and industry directories.
- Directory consistency - Is your name, address, and phone number the same everywhere AI looks?
- Answer-format content - Pages that directly answer the questions people ask, structured so AI can extract and cite them.
The speed advantage
Traditional SEO changes take 3-6 months to show results. AEO works faster. AI engines re-query their data sources regularly, so changes to your structured data, Google Business Profile, or content can be picked up within days to weeks. The feedback loop is short enough that you can make a change, re-scan, and measure the difference.
How to check your AEO score
AEO Grader queries ChatGPT, Gemini, Claude, and Perplexity with 60 real prompts about your business. It scores you on brand recognition, competitive position, contextual relevance, sentiment, and citation authority. The scan takes about 60 seconds and is free.
Most local businesses score below 40 out of 100. That means AI either does not know they exist or actively recommends their competitors instead.
