What is answer engine optimization (AEO)? A practical guide for 2026

Why AEO matters now

Buyers increasingly ask an AI assistant "what is the best X for Y?" and read a short list of names instead of ten links. If your brand is not in that list, you are not in the consideration set, even if you rank well on Google. The answer is often the whole experience: many of these questions end without a click.

How answer engines decide what to say

AI assistants answer from two places:

1. What the model learned in training. Brands that are described often, consistently and positively across the web are more likely to be "remembered" and recommended.
2. What the engine retrieves live. Engines with web search (Perplexity, ChatGPT search, Google AI Overviews) fetch pages at question time and cite them. Clear, extractable passages on crawlable pages get quoted.

In both cases the engine is looking for confident, corroborated facts: who you are, what you do, who you are for, how you compare, and what it costs.

The four parts of AEO

Part	What it means	Typical work
Measurement	Know how often each engine names you, in what position, and who it names instead	Track a fixed set of buyer questions across engines on a schedule
Content	Pages that answer buyer questions directly	Answer-first pages, comparison pages, FAQs, pricing and specs in plain text
Technical access	Let AI crawlers read your site	robots.txt that allows GPTBot, ClaudeBot, PerplexityBot and others; llms.txt; schema markup; server-rendered text
Third-party proof	Be described on the sites engines cite	Reviews, directories, comparison articles, forums, press, Wikipedia-style references

How to start in one week

1. Write down 20 to 50 questions your buyers ask, in their words: "best accounting software for freelancers in India", "X vs Y", "is X worth it".
2. Ask every major engine those questions and record who is named. Do it more than once: answers vary between runs.
3. Fix the facts. If an engine states a wrong price, feature or location, publish the correct fact clearly on your site and on the sources it cites.
4. Publish answer-first pages for the questions you lose: a direct two-sentence answer at the top, then details, a table and an FAQ.
5. Open your site to AI crawlers and add an llms.txt file that summarises who you are.
6. Re-measure monthly. Engines with live search can reflect changes within weeks; model memory moves more slowly.

Get AI Vizible automates steps 2, 3 and 6: it sends your buyer questions to six AI engines on a schedule, reports your visibility, position, share of voice, citations and sentiment against competitors, flags wrong claims, and turns the gaps into a prioritised to-do list.

Common AEO mistakes

• Tracking one engine. ChatGPT, Gemini, Claude, Perplexity, Grok and DeepSeek often disagree. Measure all of the ones your buyers use.
• Asking once. A single answer is an anecdote. Visibility is a percentage across many questions and runs.
• Hiding facts in images or scripts. Prices, features and locations should be in plain HTML text.
• Only optimising your own site. Engines lean heavily on third-party descriptions of you.
• Chasing every prompt. Focus on the questions that lead to revenue.
