What is AEO?
Answer Engine Optimization (AEO) is the practice of getting a brand named, recommended, or cited inside the answers that AI assistants such as ChatGPT, Claude, Gemini, and Perplexity generate, the way SEO gets a page ranked in Google results.

An answer engine does not return ten links. It writes one answer and names a handful of brands in it. There is no page 2, so a brand is either in the answer or it is not. AEO is the work of being in it.
The inputs are different from SEO. Backlinks and domain authority barely register; what the engines reward is a page that answers the exact question in plain sentences, comparison pages against the competitors it already names, consistent facts about the company everywhere it is mentioned, and structured data that makes those facts machine-readable.
AEO is measured by asking the engines the questions your customers ask and recording who gets named. That measurement is what an AI visibility tool such as helloAISearch automates: it sends your prompts to the four engines on a schedule, highlights your brand in the answers, and computes share of voice against competitors.
Example
A freelancer asks ChatGPT "best invoicing tool for freelancers". ChatGPT names three products. AEO is the work of being one of the three, and of being named first.

Write a comparison page for “alternatives to Competitor A”
This prompt came up 4× this week and Competitor A took every mention. A direct comparison page closes a 9-point Share of Voice gap. About an hour.
Questions people ask next
Is AEO the same as GEO?
Nearly. GEO (Generative Engine Optimization) is the academic term for the same practice; AEO is the one operators use. Both mean getting named inside generated answers. Some people use AEO for featured snippets and voice assistants too, but in 2026 the working meaning is AI answers.
Does AEO replace SEO?
No. Google still sends most web traffic, and Gemini and Perplexity lean on search indexes. AEO sits beside SEO: keep ranking for Google, and separately make sure the AI engines name you.
How do I measure AEO?
Send the engines your customers' questions on a schedule and record whether your brand or a competitor is named. Share of voice, mentions of you divided by mentions of everyone you track, is the number that moves when it works.
