Free AEO checker: is your brand named by ChatGPT, Gemini and Perplexity?
The free AEO checker (an AI visibility checker and AEO grader) asks ChatGPT, Gemini and Perplexity three questions a buyer in your sector would ask, in your market and language, and shows which brands each answer names. It takes up to two minutes and needs no account. You get a snapshot of nine answers, not a ranking or a forecast.

- How does the audit work?
- We write three questions a buyer in your sector would ask, then ask each one to ChatGPT, Perplexity and Gemini. The result shows which brands each answer names.
What does the free AEO checker do?
You describe your brand
Brand, sector, market (Luxembourg, Belgium, the Netherlands or France), language (English, French or Dutch) and a work email.
GeckoBoost writes three buyer questions
Questions a prospect in that market would type into an assistant, plus up to ten likely competitors.
Three assistants answer live
Each question goes once to ChatGPT, Gemini and Perplexity: nine answers in all.
You read who is named
How many answers name you (nine when every assistant replies), and which brands are named in your place.
How does the free test compare with full tracking?
| Free checker | GeckoBoost tracking | |
|---|---|---|
| Questions | 3, written for you | Your own, from 50 to 350 on paid plans |
| Assistants | ChatGPT, Gemini, Perplexity | Up to 4 (Starter) or 7 (Pro, Agency), chosen among these three, Google AI Overviews, AI Mode and Copilot. Claude is a paid option on Pro and Agency |
| Answers | One per question and assistant, once | Repeated daily (weekly for Claude), kept over time |
| Markets | Luxembourg, Belgium, Netherlands, France | Adds the United Kingdom, the United States and Germany |
| Sources cited | Not shown | Shown, with the domains cited instead of you |
| Limit | 3 a day per email and per IP address | Set by the plan |
One answer is a sample, not a verdict. Assistants vary from one run to the next and each engine draws on its own sources, so a second run may differ.
“On the same query, the domains cited by two engines overlapped very little: an average Jaccard index of 0.08 over 154 engine pairs. On "best AEO agency", the agency named by four engines on 31 October was named by two on 10 November.”
What does the checker not test?
- Your website (crawler access, indexing directives, text without JavaScript).
- Google rankings, AI Overviews, AI Mode, Copilot and Claude.
- Whether what the assistants say about you is accurate.
Three site checks you can run yourself
- Crawler access (documented). Make sure robots.txt and your firewall let through Googlebot, OAI-SearchBot (ChatGPT search) and PerplexityBot. Each vendor documents its user agent, and OpenAI and Perplexity publish their bots' IP addresses.
- Indexing directives (documented). A `noindex` or `nosnippet` tag on a key page limits how Google can show it: Google writes (21 May 2025) that "more restrictive permissions will limit how your content is featured in our AI experiences".
- Text without JavaScript (documented by Bing, heuristic for the others). Open the page source: your main answer, prices and contact details should be in the HTML. Bing advises against (read on 31 October 2026) "hiding critical content behind client-side rendering".
“Sites that are opted out of OAI-SearchBot will not be shown in ChatGPT search answers, though can still appear as navigational links.”
What should you do with your result?
- Named nowhere (heuristic). Start with the site checks above, then pages that answer buyer questions directly. Our guide to boosting your AEO lists ten actions.
- Named by one assistant only (heuristic). Engines use different sources. See how to get cited by ChatGPT.
- Competitors named instead (heuristic). The questions they win are the ones to measure first.
Your result has its own link to share. It is not indexed and never shows your email. New to the terms? Read what AEO is and how AEO, GEO and SEO differ.
When is a guided audit or ongoing tracking worth it?
The AI visibility tool tracks your own questions, competitors and sources over time, with a 14-day free trial (see pricing). To have the work done for you, the guided AI visibility audit adds your site and a prioritised action plan, priced on request.
We go through your free result and what tracking would add.

Is AEO legit?
AEO (answer engine optimization) is the work on how AI assistants name and cite your brand. The work is real, many shortcuts are not: Google wrote on 15 May 2026 that many AEO or GEO hacks "aren't effective or supported by how Google Search actually works".
What is AEO vs SEO?
SEO works on your position in search results, AEO and GEO (generative engine optimization) on whether AI answers name and cite you. They overlap: Google says (15 May 2026) its generative AI features are "rooted in our core Search ranking and quality systems".
How do you rank yourself on ChatGPT?
No one can promise a place. OpenAI writes (read on 30 October 2026) that "placement is not guaranteed". Documented: allow OAI-SearchBot and its IP ranges. Heuristic: clear answer pages and mentions on sites ChatGPT cites.
Is the AEO checker really free?
Yes, with no card and no account. It is limited to three runs a day per email and per IP address, plus a daily total for the site, because each run pays for nine live answers.
Which markets and languages does the free test cover?
Luxembourg, Belgium, the Netherlands and France, in English, French or Dutch. For the United Kingdom, the United States or Germany, use the tracking tool's free trial.
What do you do with my email?
We keep it with your result and contact you only if you tick the box. Without that consent it is erased after 30 days.
