GEO Scanner

I've been building websites for years (plain PHP, no framework overkill) and noticed there's barely any tooling that checks whether a site is even readable/citable by AI systems like ChatGPT, Claude, or Perplexity — just classic SEO checkers.

So I built GEO Scanner: enter a URL, get 17 checks (llms.txt, Schema.org, AI bots in robots.txt, freshness signals, heading structure...), a 0–100 score, and every check comes with a concrete fix instead of just a red X.
