What is AI answer optimization?

By Anthony Villanueva, Founder & CEO · Updated November 11, 2026

AI answer optimization is the work of getting AI tools such as ChatGPT, Perplexity, Claude and Google's AI Overviews to name your business, and describe it correctly, when someone asks a question you should be the answer to. It is also called answer engine optimization (AEO) or generative engine optimization (GEO). The work is to measure what the engines say, fix the pages and listings they read, and measure again.

How is it different from SEO?

SEO aims at a ranked list of links that a person clicks. AI answer optimization aims at the answer itself: a few sentences that name some businesses and not others, often with no click at all. In Pew Research Center's study of 900 U.S. adults' Google searches in March 2025, people who saw an AI summary clicked a regular result in 8% of visits, against 15% when there was no summary, and clicked a link inside the summary in just 1% (Pew Research Center, July 22, 2025).

The two overlap. Google says there are no extra technical requirements to appear in AI Overviews or AI Mode, and that normal SEO best practices still apply (Google Search Central). A page that cannot be crawled or indexed will not be quoted by either.

Why has it become a separate job?

Because the audience moved. Google said on May 19, 2026 that AI Mode passed 1 billion monthly users within a year of launch and that AI Overviews has over 2.5 billion (Google, Sundar Pichai). OpenAI announced 900 million weekly ChatGPT users on February 27, 2026 (TechCrunch). BrightLocal's 2026 survey found 45% of US consumers now use AI tools for local recommendations, up from 6% a year earlier (BrightLocal, February 11, 2026).

What does the work involve?

Three steps, repeated.

Measure. Ask each engine the questions your buyers ask, several times, because answers change between runs. Record whether you are named, what is said and which pages are cited.

Fix. Let the AI crawlers read your site, state plainly what you do, where and for whom, add structured data and a named author, and correct the listings and directories the engines quote.

Check again. Ask the same questions after the fix, so you can tell a real change from a lucky run.

Does the content itself make a difference?

Researchers have measured it. In the GEO study (arXiv, November 2023; accepted to KDD 2024), the best methods, which were citing sources, adding quotations and adding statistics, made a page 30 to 40% more visible in generated answers (Aggarwal et al.). That is a research result on test engines, not a promise about any one tool, but it points the same way as Google's advice: specific, sourced pages get used.

Frequently asked questions

Is AEO the same as GEO?

They are two names for the same goal: getting named in AI answers. GEO (generative engine optimization) is the name a 2023 research paper used; Sightline uses AEO.

Can I do it myself?

Yes. Start by asking ChatGPT and Perplexity your buyers' questions in fresh chats and writing down what they say. The hard part is repeating it the same way every week.

How long until it works?

Crawlers have to read your changes first. OpenAI says a robots.txt change takes about 24 hours to reach its search systems; content changes depend on when the page is next crawled and used.

Can anyone guarantee a recommendation?

No. No engine publishes how it chooses, so a guarantee is a red flag.
