Free tool: check if ChatGPT and Perplexity can find your website

I built a free scanner that tells you whether AI search engines can discover, understand, and cite your website. It's called GEOScore AI (geoscoreai.com).

Why I built it

My other project had solid Google rankings but was completely invisible to AI search tools. When I asked ChatGPT questions my site should answer, it cited competitors instead. I spent weeks manually checking every technical signal, then realized every website owner faces this same problem.

How it works

Enter your URL, hit scan. In 30 seconds you get:

1. A score from 0 to 100
2. 9 diagnostic signals evaluated individually (AI crawler access, schema markup, content structure, llms.txt, sitemap, and more)
3. Specific recommendations on what to fix

What I've learned from 2,500+ scans

Average score is about 45/100. Most websites are significantly under-optimized for AI search.

• 30% of sites block AI crawlers in robots.txt without knowing it
• Most sites lack meaningful schema markup
• Almost nobody has an llms.txt file (~5% of sites)
• Content structure is usually optimized for humans, not machine extraction

The good news: fixes are straightforward. Unblocking AI crawlers takes 5 minutes. Adding schema takes an afternoon. Most sites can jump 15-20 points in a single sprint.

Business model

Free scan, no signup. $29/month Pro tier with detailed fixes, monitoring, and historical tracking. Free tier is genuinely useful on its own.

For fellow indie hackers

If you're building a product, scan your own site. Most indie hacker products score below average because we focus on the product, not AI search.

But AI search is becoming a real discovery channel. When someone asks ChatGPT "best tool for X" and you don't come up, you're losing users. Unlike Google SEO (years of backlinks), AI readiness is mostly technical and can be improved quickly.
