I built a free tool to check if your website is visible to AI search engines

Hey IH! I'm William, and I want to share the story behind GEOScore AI — a free tool I built to help website owners figure out if AI search engines can actually find and cite their content.

The problem I noticed

I've been working in SEO for years, but about 6 months ago I started paying attention to something new: AI-powered search. ChatGPT, Perplexity, Google AI Overviews — they're all changing how people find information online. Gartner predicted a 25% drop in organic website traffic in 2025 because of AI answers, and from what I've seen, that tracks.

The thing is, most website owners have no idea whether their site is even visible to these AI systems. Traditional SEO tools don't check for this. There's a whole new set of signals that matter — things like whether your robots.txt allows AI crawlers, whether you have an llms.txt file, whether your structured data is set up for citation, and whether your content is formatted in a way that AI can actually parse and reference.

What I built

GEOScore AI scans your website and checks 11 specific GEO (Generative Engine Optimization) signals:

AI crawler access (robots.txt configuration)
llms.txt presence and quality
Structured data / Schema.org markup
Citation readiness (how quotable your content is)
Content authority signals
And several more

You get a score out of 100, plus a detailed report showing exactly what to fix. It's completely free — no signup required for a basic scan.

I also built two free companion tools: an AI Robots.txt Generator and an AI Crawler Access Checker.

What surprised me

After scanning hundreds of sites, here's what I found:

Most sites accidentally block AI crawlers. A shocking number of robots.txt files block GPTBot, ClaudeBot, or other AI user agents — sometimes intentionally, sometimes by accident with overly broad disallow rules.
Almost nobody has llms.txt. This is a new standard (like robots.txt but specifically for LLMs) and adoption is still very low. But early adopters are seeing better AI citation rates.
Structured data matters more than ever. Sites with proper Schema.org markup get cited by AI at significantly higher rates. It's not just about Google rich snippets anymore.
Content format matters. AI systems prefer content with clear headings, statistics, expert quotes, and definitive statements. Vague, keyword-stuffed SEO content actually performs worse in AI search.

Where things stand

The tool is live at geoscoreai.com. It's free, bootstrapped, and I'm iterating based on user feedback. I'm also building out a deeper scan feature that provides an AI-generated report with prioritized recommendations.

I'd love to hear from other founders:

Are you thinking about AI search visibility for your products?
Have you noticed any changes in your traffic patterns from AI search?
What would make a tool like this more useful for you?

Happy to answer any questions about GEO or the technical side of building this.
