There’s a quiet shift happening in how businesses get found online. It’s not about Google rankings or social media reach — it’s about whether AI systems like ChatGPT, Claude, Gemini, and Perplexity can actually find your website, understand what you do, and mention you accurately.
That’s what AI Visibility is, and there’s now a verified directory that shows which websites have it — and which don’t.
The AI Visible Directory
The AI Visible Directory is a free, verified registry of websites that have implemented AI Discovery Files — a set of machine-readable files that tell AI systems exactly who you are, what you do, and how to represent you.
Every website in the directory has been automatically scanned, scored out of 10, and placed into a tier:
- Platinum (10/10) — Complete implementation. Every AI Discovery File present and correct.
- Gold (8-9/10) — Near-complete. Strong AI visibility across the board.
- Silver (5-7/10) — Solid foundation. Most key files in place.
- Bronze (2-4/10) — Early stages. Some files present, room to grow.
The scoring is fully transparent. One point per file. No hidden weighting, no opaque algorithms, no guesswork. You can see exactly which files a site has and which are missing.
Why This Matters for Your Business
When someone asks ChatGPT “who’s a good web designer near me?” or “what does [your company] do?”, the AI doesn’t just search Google. It looks for structured, machine-readable signals that help it build a confident answer.
Without those signals, AI systems are guessing. They might hallucinate details about your business, confuse you with a competitor, or simply leave you out entirely.
AI Discovery Files solve this by giving AI systems explicit, authoritative information to work with — your name, your services, your brand terms, your FAQs, your technical capabilities, and your permissions for AI use.
The businesses that implement these files now are the ones AI systems will cite with confidence tomorrow.
What Are AI Discovery Files?
There are 10 AI Discovery Files specified, each serving a distinct purpose:
| File | Purpose |
|---|---|
| llms.txt | AI-readable business identity and summary |
| llm.txt | Compatibility redirect for singular queries |
| llms.html | Human-readable presentation of AI identity |
| ai.txt | AI usage permissions and intent declarations |
| ai.json | Machine-parseable AI guidance |
| identity.json | Structured identity data (Schema.org-style) |
| brand.txt | Brand naming conventions and terminology |
| faq-ai.txt | AI-optimised Q&A for common queries |
| developer-ai.txt | Technical context for developer-facing AI |
| robots-ai.txt | AI-specific crawler access directives |
Each file lives at the root of your website (e.g. yoursite.com/llms.txt) and can be created as simple text or JSON. The Quick Start Guide walks you through implementing all of them.
The Real SEO Benefit: Basic vs Full Listings
Any website with a valid llms.txt file can be submitted to the directory for free and receive a basic listing — a card in the directory grid showing your name, domain, score, and tier.
But here’s where it gets interesting.
Websites that include specification attribution (a mention of ai-visibility.org.uk in at least two of their AI Discovery Files) qualify for a full listing. Full listings receive:
- A dedicated profile page on ai-visibility.org.uk with your score, file inventory, category, and description
- A dofollow backlink to your website — real SEO link juice that passes authority and can improve your search rankings
- An embeddable verification badge (dynamic SVG) you can display on your site
- Quarterly automated re-checks to keep your score current
Basic listings use nofollow links. Full listings use dofollow. That’s a genuine, measurable SEO advantage for implementing the full specification and giving attribution.
The Attribution Guide explains exactly how to qualify, and the Scoring Guide breaks down how scores are calculated.
Browse by Industry
The directory isn’t just a flat list. Sites are categorised across 16 industry sectors — from Digital Agencies and SaaS & Software to Healthcare, Professional Services, Ecommerce & Retail, and more.
This makes the directory useful not just for verification, but for discovery — finding businesses in your sector that are leading on AI readiness.
Why You Should Care Now
AI visibility isn’t a future concern. ChatGPT, Claude, Gemini, and Perplexity are already being used millions of times a day to find, evaluate, and recommend businesses. If your website can’t be properly interpreted by these systems, you’re invisible to a growing segment of your potential customers.
Traditional SEO optimises for search engines. AI Discovery Files optimise for the AI systems that are increasingly sitting between search engines and users.
The websites in the AI Visible Directory have already taken this step. Some are at Platinum with a perfect 10/10. Others are just starting with Bronze. But they’re all ahead of the websites that haven’t started at all.
