Free GEO Checker — Test Your AI Search Visibility
The LightSite AI Generative Engine Optimization Checker is a free AI search readiness audit that checks whether AI assistants can identify your business correctly, whether your site exposes machine-readable business signals, and whether your content is easy for LLMs to parse and cite. Find the biggest AI visibility gaps, see what is blocking LLM discoverability, and get prioritized fixes.
What the GEO Checker Audits
The checker evaluates your website across the key dimensions that shape AI discoverability:
- Structured data coverage — JSON-LD schema types present, missing, or incomplete
- Crawlability checks — whether AI bots can access and parse your key pages
- Entity clarity score — how clearly your business identity is represented in machine-readable form
- AI discoverability gaps — specific areas where your site fails to communicate with LLMs
- Missing schema types — Organization, Product, FAQ, Review, and other entity types AI assistants look for
- Weak machine-readable sections — pages or content areas that lack structured signals
What You Get in the Report
After scanning your site, you receive a detailed breakdown that includes:
- An overall AI readiness score with dimension-level grades
- A list of structured data types found and missing on your domain
- Specific recommendations ranked by impact — what to fix first
- Comparison of your readiness against AI search best practices
- Identification of pages that AI crawlers can and cannot extract facts from
Who Should Use This AI SEO Checker
This tool is built for marketing teams, SEO professionals, and agencies who need to understand how their websites perform in AI-powered search — not just traditional Google results. Whether you are a startup validating your AI visibility or an enterprise team benchmarking against competitors, the GEO checker gives you an actionable baseline.
Why You Can Trust This Tool
The GEO Checker is built by the team behind LightSite AI's structured data platform and is based on empirical research across 5 million AI bot requests. It evaluates the same signals used by ChatGPT, Gemini, Claude, and Perplexity when deciding which brands to cite in AI-generated answers. LightSite AI is rated 4.8 on G2 and 5.0 on Trustpilot based on verified reviews.
What Your GEO Score Means
Your score reflects how well your website communicates with AI systems — a high score means your content is structured in ways that LLMs can parse, cite, and recommend. A low score means AI assistants are likely ignoring your site — even if you rank well in traditional search.
