0-100 score on AI-era signals — llms.txt, JSON-LD, robots.txt AI rules, content depth, hreflang
GEO (Generative Engine Optimization) is the discipline of making your site rank in AI answer engines — ChatGPT, Claude, Perplexity, Gemini — alongside traditional search. This audit scores any URL on 15+ AI-era signals (llms.txt, JSON-LD FAQPage coverage, AI-bot robots.txt rules, content depth, hreflang) and gives you a prioritized punch-list for improvement.
Generative Engine Optimization — the 2024-2026 discipline of making your content citable by LLMs (ChatGPT, Claude, Perplexity, Gemini) in addition to ranking on Google. Overlaps ~80% with modern SEO but adds AI-specific signals.
Often used interchangeably. Some split them: AEO (Answer Engine Optimization) = getting cited by ChatGPT/Perplexity/etc. GEO = broader, includes the above + making your site navigable by LLM agents. This tool scores both.
Because it's a free, low-adoption signal — early adopters get outsized value. Our own tools page scores 95+ partly because we ship llms.txt.
Usually: (1) visible content depth — if your page is 100% JS-rendered with no SSR, crawlers see nothing, (2) JSON-LD absence — add FAQPage + SoftwareApplication where applicable, (3) robots.txt that explicitly allows AI bots.
80+ is solid. 90+ means you've done structured-data right AND have good content depth AND are AI-friendly. Realm by Rook's utility pages score 95+.
