## Frequently Asked Questions

What is AI visibility?

AI visibility measures how often your brand is mentioned or cited by AI platforms like ChatGPT, Perplexity, Gemini, and Claude when they answer questions relevant to your industry. Unlike traditional SEO rank, AI visibility depends on brand authority, structured data, content depth, and whether AI crawlers can access your site.

What is llms.txt?

llms.txt is an emerging standard (llmstxt.org) that works like a sitemap for AI models. A file at yoursite.com/llms.txt tells AI systems what your site is about, which pages to prioritise for training/indexing, and what to skip. Sites with llms.txt get clearer entity recognition from LLMs.

Why would my brand be blocked from AI crawlers?

Many sites accidentally block AI crawlers in robots.txt using "Disallow: /" for unfamiliar user agents. GPTBot (OpenAI) and ClaudeBot (Anthropic) are commonly blocked, which makes your site completely invisible to those AI systems when generating responses.

How does the AI Visibility Score work?

The score (0–100) is a weighted composite of four signal groups: Domain Authority (30%), Technical SEO (25%), AI Accessibility (25% — crawler access + llms.txt + sitemap), and Content Signals (20% — Organization schema, sameAs, FAQPage, canonical tags). Each platform weights these differently.

How do I improve my AI visibility?

The highest-impact actions are: (1) Unblock AI crawlers in robots.txt, (2) Create /llms.txt, (3) Add Organization JSON-LD schema with sameAs links to YouTube, LinkedIn, and Wikipedia, (4) Publish FAQ content with FAQPage schema, (5) Build backlinks from high-authority sites your industry AI models treat as trusted sources.

## FAQ

### What is AI visibility?

AI visibility measures how often your brand is mentioned or cited by AI platforms like ChatGPT, Perplexity, Gemini, and Claude when answering questions. Unlike traditional SEO rank positions, AI visibility depends on brand authority, structured data quality, AI crawler access, and content depth.

### What is llms.txt and why does it matter?

llms.txt is an emerging standard (similar to robots.txt but for AI models) that allows websites to tell LLMs what their site is about and which content to prioritise. A file at yoursite.com/llms.txt helps AI systems like ChatGPT and Claude form clearer brand entity associations and cite your content more accurately.

### What AI crawlers does this tool check?

The tool checks 8 AI user agents in your robots.txt: GPTBot (OpenAI/ChatGPT), ClaudeBot (Anthropic/Claude), PerplexityBot (Perplexity), GoogleOther (Google AI/Gemini), Applebot-Extended (Apple AI), CCBot (Common Crawl training data), Meta-ExternalAgent (Meta AI), and Bytespider (ByteDance AI).

### How is the AI Visibility Score calculated?

The score (0–100) combines four signal groups: Domain Authority (30 pts), Technical SEO/PageSpeed (25 pts), AI Accessibility — crawler access, llms.txt, sitemap (25 pts), and Content Signals — Organization schema, sameAs, FAQPage, canonical (20 pts). Platform-specific scores weight these differently for each AI system.
