Buyers ask AI now. Are you in the answer?
Semrush found Google AI Overviews on 88% of the 400 US desktop commercial keywords it tracked (published 21 October 2026). When an assistant recommends three companies and you're not one of them, you never see the lost buyer.

SEO, AEO and GEO: what's the difference?
| What it means | What helps | Where it shows | |
|---|---|---|---|
| SEOsearch engine optimisation | Ranking in traditional search results and the local pack | Crawlable pages, relevant content, links, a strong Google profile | Google and Bing blue links, the local pack |
| AEOanswer engine optimisation | Being the source an engine uses for a direct answer: featured snippets, People Also Ask, voice, AI Overview answers | Clear questions with short, direct answers; lists, tables, structured data | Featured snippets, People Also Ask, voice assistants, the answer box at the top of AI Overviews |
| GEOgenerative engine optimisation | Being named or cited when an AI assistant writes its own response | AI crawler access, a clear and consistent description of your business, trusted third-party mentions, original information | ChatGPT, Perplexity, Gemini, Claude, Copilot, Google AI Mode and the sources cited in AI Overviews |
AEO is about passages that answer a question. GEO is about your business being a name an AI system trusts enough to recommend. theStacc covers both: readiness and content for AEO with Blog & SEO, tracking and fixes for GEO.
Questions
How does theStacc measure AI visibility?
By asking each AI app your buyer questions every weekday and counting how often you're named: for example, "named in 14 of 40 answers". There are no made-up scores. Every number links to the answers behind it.
Which AI assistants does it check?
ChatGPT, Gemini, Google AI Mode and Perplexity.
Can you guarantee AI will recommend us?
No one can. theStacc shows where you stand, why, and drafts the fixes that give AI a reason to name you.
Do I need an llms.txt file?
It's optional and not yet an official standard, but it's a low-effort way to give AI systems a clear summary of your site. theStacc drafts it for you.
