Answer engine optimization, usually shortened to AEO, is the practice of writing and structuring content so that AI-powered tools, like Google's AI Overviews, ChatGPT or Gemini, can find it, understand it and cite it when they generate an answer to someone's question. It's a real, specific shift in how people search. It's also, for a small business, mostly a matter of doing the fundamentals well rather than learning an entirely separate discipline.
How it's different from regular SEO
The core difference is what counts as success. Traditional SEO competes for a click: you rank, someone clicks your link, they land on your page. AEO competes for a citation: an AI tool reads your content, decides it answers the question well, and either names your business directly in its answer or links to you as a source, sometimes without the person ever visiting your site at all.
That changes what "winning" looks like. You can be the source behind an answer and never see it in your normal analytics, because no click happened.
How big is this, really?
Estimates for how often AI Overviews show up in Google searches vary a lot depending on who's measuring and what kind of queries they're tracking, from roughly 20% to 50% of US searches. It's worth knowing that the picture looks different for the kind of searches a local trade cares about most: one tracking service found AI Overviews appear in only about 7% of searches with clear local intent, well below the overall rate. AI answers are real and growing, but for "plumber near me" style searches, plain search results, Google's map pack and reviews still do most of the work right now.
What actually helps, and it overlaps heavily with SEO
The practices that help a page get cited by an AI tool are, for the most part, the same practices that help it rank normally:
- Clear, direct answers to specific questions, the same standard covered in how to write a services page that ranks
- Accurate schema markup, so a machine can parse facts about your business precisely instead of guessing, covered in what is schema markup
- Consistent information everywhere you appear, since research into how AI tools evaluate local businesses points to mismatched hours or contact details across platforms as a specific reason a system loses confidence in a listing
- A real library of Answers to genuine customer questions, not filler content, which is the same standard covered in do contractors need a blog?
If you've already done the things covered elsewhere in this Bulletin, you've already done most of what AEO asks for. See how to get your business recommended by AI assistants for the practical checklist and the research behind it.
Where it genuinely differs from SEO in practice
- Measurement is harder. Rank tracking tools show you a position. Checking whether an AI tool cites you means actually asking it the questions your customers would ask, repeatedly, since answers aren't stable the way a search ranking is.
- Different tools draw from different sources. Research on this found only about 11% overlap in which websites ChatGPT, Gemini and Perplexity actually cited for the same queries. There's no single trick that covers every assistant.
- Star ratings seem to matter less than assumed. One study found close to no correlation between a business's rating and how often it got recommended by AI tools, which suggests consistency and real content may matter more than chasing a perfect score.
The honest takeaway for a small business
Don't treat AEO as a separate project competing for your time against SEO. Treat it as the same work, done well: accurate information, real answers to real questions, and schema that matches what's true, kept consistent everywhere your business appears.
Questions
Do I need special tools to do AEO?
Not to start. The fundamentals, accurate content and schema, don't require anything beyond what's covered elsewhere in this Bulletin. Tools that let you query multiple AI assistants and track citations exist, but they're an optimization on top of the basics, not a replacement for them.
Is AEO more important than traditional SEO now?
For most local trade searches, no, not yet. AI Overviews remain a small share of local-intent searches specifically. Both are worth doing, and they share almost all the same underlying work.
Will focusing on AEO hurt my regular SEO?
No. The practices reinforce each other. There's no meaningful trade-off between the two for a small business doing the fundamentals well.
