Koa Audit — Free SEO, GEO & A11Y Audit - Check if your site is ready for Google AND ChatGPT

Google isn't the only one reading your site anymore. ChatGPT, Perplexity, Gemini — they're all crawling the web, and most sites aren't ready. Koa Audit analyzes your website across 3 dimensions in ~30 seconds: 🔍 SEO — meta tags, headings, Open Graph, Core Web Vitals 🤖 GEO — structured data, llms.txt, AI bot access, citability ♿ A11Y — WCAG checks, ARIA, keyboard navigation 60+ checks, 3 scores, zero signup. Just paste your URL.

Hey PH! 👋 I'm Matthieu, freelance dev from France. I build tools when I see a gap — and this one came from a frustration: none of the existing SEO auditors check if your site is optimized for AI search engines. With ChatGPT, Perplexity and Gemini answering more and more queries, your site needs to be "citable" by LLMs — not just indexable by Google. That's what GEO (Generative Engine Optimization) is about. Koa Audit checks things like: Do you have an llms.txt file? Is your structured data rich enough? Are AI bots allowed in your robots.txt? Is your content structured to be cited? Would love your feedback — what checks would you add? 🙏
