Your site ranks on Google. Does ChatGPT cite it?

The open-source Answer Engine Optimization (AEO) & Generative Engine Optimization (GEO) toolkit.

GEO Optimizer is the open-source engine behind GeoReady, the hosted AI visibility audit at geoready.dev. Run it here from the terminal, or in the browser on geoready.dev.

One command scores any website 0–100 on whether ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews can crawl it, understand it, and cite it — then tells you exactly what to fix.

uvx --from geo-optimizer-skill geo audit --url https://yoursite.com

No install, no account, no API key. Runs in seconds.

No terminal? Paste your URL into the browser version instead. Same engine, free, no account:

The browser audit on geoready.dev: paste a URL, read the score, the nine category results and the free fixes. Live run on geoready.dev itself, 17 October 2026.

What is GEO Optimizer?

GEO Optimizer measures how visible a website is to AI answer engines — ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude — scores it 0–100, and generates the fixes. It is free, MIT-licensed, and runs as a CLI, a Python library, an MCP server, a GitHub Action, or an Astro integration.

Also called GEO, AI SEO, or LLM SEO — same problem: an answer engine gives one response and cites a handful of sources. Ranking on Google does not make you one of them. Being reachable, parseable, and quotable does.

What a real audit looks like

Two runs of geo audit, September 2026. example.com has no robots.txt, no llms.txt, and no structured data. geoready.dev is built with this engine's own Astro integration. Excerpts, condensed from the full text output.

[█░░░░░░░░░░░░░░░░░░░] 8/100
❌ CRITICAL — Site is not visible
   to AI search engines

📋 PRIORITY NEXT STEPS:
1. Create robots.txt with Allow rules
   for AI bots (GPTBot, ClaudeBot,
   PerplexityBot)
2. Create /llms.txt for AI indexing
3. Add WebSite JSON-LD schema
4. Add Organization JSON-LD schema
5. Add FAQPage schema with site FAQs

Across 1,800+ sites audited through GeoReady (latest audit per domain, as of 17 October 2026), the median score is 59/100, 58% publish an llms.txt and 76% ship JSON-LD structured data. 58% of them land in the Foundation band (36–67), 28% in Good, 12% in Critical and 2% in Excellent. Scores mix rubric v1 (engine 4.13 to 4.18) and v2 (4.19). The sample is self-selected (people who chose to audit their site), so treat it as directional, not a census of the web.

Where does your site land? Run the free audit and compare your score with the median, or run geo audit above.

Then it writes the fixes

geo fix turns the audit into files: robots.txt rules for all 27 AI bots, llms.txt, JSON-LD schema, AI discovery endpoints, and meta tags. It previews by default and writes only with --apply. The score after fixes is the tool's own estimate, not a measured result.

After the one-shot audit

geo audit is a snapshot. It can't tell you that your score dropped after last Tuesday's deploy, or whether citations started appearing once your fixes shipped. geo history, geo drift, and geo track help — but only when someone remembers to run them.

The hosted platform runs the same engine on a schedule, so the watching happens without you:

• Free plan — audits, your last 5 reports, and one real AI answer check a week (Perplexity).
• Pro / Agency, from $19/mo — weekly score monitoring, regression alerts, multi-site portfolios, client reporting. Pricing.

Create a free account · Free web audit, no account · Get the free 160-page GEO Readiness Manual

Same engine everywhere: the platform adds what a local CLI cannot — server-side monitoring, history, and team features.

Open source vs hosted — the full comparison

Is AI citing you? Ask it directly.

geo citations sends the questions your customers ask to real answer engines, then reports whether your brand is mentioned, whether your domain is cited as a source, and which competitors are cited instead.
