GEO tools: the free toolkit

Start with the three questions that decide citability

1. Can AI engines read you? Blocked crawlers and JS-only pages end the story before content matters — check how AI sees your page, crawler access and your server logs.

2. Is the content shaped to be lifted? Engines quote self-contained passages, not essays — score a page with the GEO checker, a draft with GEO score, and your answer paragraphs with the capsule checker.

3. Are you actually cited? Measure, don't guess: AI Overview checker and the AI visibility check show who the engines name.

The supporting cast most sites skip

• llms.txt generator and validator — the index agentic readers fetch first.
• Schema validator and author markup — machine-readable facts and authorship engines can attribute.
• Agent-readiness score — one number for how consumable your site is for AI agents.

When free tools stop being enough

Free checks answer what is broken now. What they cannot do is watch your queries weekly, alert you when a competitor takes your citation, or fix the findings. That is the paid layer: see the honest comparison of AI visibility tools — including ours.

Questions

What are GEO tools?

Tools for Generative Engine Optimization — making pages readable, verifiable and citable for AI answer engines. They split into three jobs: can engines access you, is your content shaped for citation, and are you actually being cited.

Are these tools really free?

Yes — every tool linked on this page runs without signup. Some deeper checks (live SERP probes) have daily limits because they cost us real API calls.

GEO vs SEO — do I need both?

They overlap ~70%: solid technical SEO is the foundation GEO builds on. The GEO-specific part is answer-shaped content, machine-readable authorship and access for AI crawlers — that is what these tools check.
