What's a GEO citation audit, and why does it matter?

When a buyer asks Perplexity, ChatGPT, Claude, or Google AI Overviews "what's the best X for my use case", the answer they get cites two or three sources by default. Those cited sources are the new front page. If your SaaS is on the citation list, you're in consideration. If it's not, you're invisible — even if your SEO ranking is decent.

Generative Engine Optimization (GEO) measures citation share: out of N queries × M engines, how often is your domain cited? It's the AI-era analogue of click-through rate from blue-link SEO. Like SEO, it has its own measurement loop and its own remediation playbook. Unlike SEO, the playbook is still being written — and most SaaS teams haven't started measuring yet.

What this audit gives you

  • Per-engine citation status across Perplexity, ChatGPT search, Claude, and Google AI Overviews. Three replicates per engine to average out stochasticity.
  • Competitive citation gap — which competitors are cited where you aren't, and the specific phrases the engines used to introduce them.
  • Prioritised "why not cited" diagnosis — usually one of: thin content surface for the query, weak Schema.org grounding, missing llms.txt, or positioning that doesn't match the query intent. We tell you which.
  • Concrete next-action list — 3–5 things ranked by leverage. Most fixable items are content rewrites; some are technical (Schema.org, llms.txt authoring); a few are positioning (which we flag but don't claim to solve).

Why we run this for free

Two reasons. First, the indie SaaS founders we'd want as customers don't yet know they have a GEO citation problem — measuring it for them is the most useful thing we can do. Second, the audit takes ~30 minutes of operator time per submission to run via our internal geo-citation-audit skill — sustainable as a free signal-generating tool, not a flagship product. If demand is high enough we'll automate it; until then it's a hand-curated free service.

What we don't do

  • We don't add you to a marketing list. Your email is used to deliver the audit and nothing else.
  • We don't share or aggregate your queries. Each submission is handled in isolation.
  • We don't audit one query 100 times across many engines. 3 replicates × 4 engines × 5 queries = 60 engine calls. More than that has diminishing returns.
  • We don't promise to make you cited. The audit is diagnostic. The remediation is on you (or, optionally, on us if you become a customer).

Built on the same skill we use internally

The audit is run through our geo-citation-audit skill — the same one that powers our Generative Engine Optimization role. If you find the audit useful and want it running every week as part of a full marketing team, that's our product. If you just want the one-shot diagnostic, this free tool is the answer.

GEO audit FAQ

How do I get my startup cited by ChatGPT and Perplexity?
Start by measuring where you stand: run a GEO citation audit to see which engines cite you — and which cite competitors instead — for your target queries. Then fix the common gaps: a thin content surface for the query, weak Schema.org structured data, a missing llms.txt file, or positioning that does not match the query intent. The free audit above returns your per-engine citation status plus a prioritised list of what to fix first.
What are GEO (generative engine optimization) tools?
GEO tools measure and improve how often AI engines — Perplexity, ChatGPT, Claude, and Google AI Overviews — cite your site when answering questions in your category. They track citation share across engines and queries, diagnose why an engine cites a competitor instead of you, and recommend fixes such as structured data, an llms.txt file, and content rewrites. This page runs a free one-shot GEO citation audit; Ceres's Generative Engine Optimization agent runs the same audit continuously as a weekly tracked metric.
How do I check if AI engines mention my brand?
Ask each engine your target queries directly and note whether your domain is cited — but engine answers are stochastic, so you need several replicates per query and per engine to get a stable read. The free audit on this page does that for you: three replicates across four engines (Perplexity, ChatGPT, Claude, Google AI Overviews) per query, returned as a per-engine citation report within 24–48 hours.
Is GEO the same as SEO?
Related, but not the same. SEO optimises for blue-link rankings on Google's main results page; GEO optimises for being cited inside AI-generated answers. They share a content base — structured data, clear claims, and primary-source citations help both — but they measure different signals, and a page that ranks well on Google can still fail to be cited by AI engines. Most teams already measure SEO and have not started measuring GEO.
