When a potential customer asks ChatGPT “best [your service] in [your city]” you simply don’t appear. Your competitor does. Not because they’re better. Because their site is structured the way AI reads.
Symptom: declining inbound despite stable Google rankings
AI is already talking about you. It has wrong opening hours. An outdated service list. A description that contradicts your homepage. Customers arrive with incorrect expectations — or don’t arrive at all.
Symptom: “I thought you were…” conversations increasing
Only 38% of top-ranked Google pages appear in ChatGPT responses. Backlinks, keyword density, page authority — these have near-zero correlation with LLM citation. The game changed. The tools didn’t.
Symptom: organic traffic flat despite top-10 rankings
Enter any URL. Legible scores your site on six dimensions LLMs actually care about: entity clarity, factual density, internal consistency, schema presence, freshness signals, and claim verifiability. You get a Legibility Score (A–F) and specific issues on specific pages.
Free on any URLLegible generates your /llms.txt file, improves your Schema.org markup, and builds a verified ground truth fact sheet. Contradictions between your own pages are flagged and resolved. The only tool that won’t let you push false claims to AI.
Agents query ChatGPT, Claude, Perplexity, and Gemini weekly with questions relevant to your business. You are alerted when you appear, when you’re absent, and when AI responses contain inaccurate information about you.
