What is AEO (Answer Engine Optimization)?

Answer Engine Optimization (AEO) is the practice of making sure AI answer engines — ChatGPT, Perplexity, Google Gemini and Google’s AI Overviews — find your business, describe it accurately, and recommend it when people ask a relevant question.

For twenty years, being found online meant ranking on Google’s list of blue links. That world is ending. Hundreds of millions of people now ask an AI a question and get a single, synthesized answer — often with no links clicked at all. If the AI doesn’t name you, you don’t exist for that buyer. AEO is how you get named.

A simple definition

Think of AEO as SEO for the age of AI. Where SEO optimized to rank a page in a list, AEO optimizes so your brand and facts become part of the answer itself. There are three jobs:

• Get found — the engine can crawl and understand your content.
• Get understood — the engine knows correct, consistent facts about you.
• Get recommended — the engine names you when someone asks a buyer question in your category.

Why AEO matters now

Three shifts happened at once. First, AI assistants exploded in usage — ChatGPT alone has hundreds of millions of weekly users. Second, Google put AI Overviews above the classic results on a large share of searches. Third, buyers changed behavior: instead of “best plumber near me” and scrolling, they now ask “who’s the best emergency plumber in my area and what will it cost?” and act on the answer.

The result is the zero-click reality: the AI answers, the user acts, and most businesses never see the traffic — because they were never in the answer. Being recommended by the AI is the new page-one ranking.

How answer engines actually pick who to name

Modern engines combine two things: what the model already “knows” from training, and what it retrieves live from the web in the moment (a technique called retrieval-augmented generation, or RAG). When you ask for a recommendation, the engine typically searches, reads the top results and trusted sources, and synthesizes an answer — naming the businesses that appear most consistently and credibly.

That means the levers that get you named are knowable:

• Crawlability — the AI crawlers (GPTBot, OAI-SearchBot, PerplexityBot, Google) can read your site.
• Consistency — your name, category, location and offers match everywhere, so the model isn’t uncertain.
• Structure — schema markup and clear, question-first content let the model extract clean facts.
• Source presence — you show up on the directories, review sites, and editorial pages the AI pulls from.
• Trust — real reviews, credentials, and authoritative mentions tip the AI toward recommending you.

The four things to measure

You can’t improve what you don’t measure. A useful AI visibility score tracks four dimensions:

Most businesses we scan discover the same thing: the AI already knows their brand, but recommends them in roughly zero percent of relevant buyer questions. That gap is the entire opportunity.

Where to start

Start by finding out where you stand today. Run a free AI Visibility Scan to see exactly how ChatGPT, Perplexity, Gemini and AI Overviews describe your business, whether they recommend you, and who they name instead — then work the prioritized fix plan. From there, follow the AEO Playbook step by step.
