What is AI Visibility?

Definition

AI Visibility is a measure of how effectively AI crawlers (GPTBot, ClaudeBot, CCBot, Google-Extended, Googlebot) can access, parse, and extract accurate information from your website. It determines whether your content appears in AI-generated answers, chatbot responses, and AI-powered search results.

Unlike traditional SEO, which focuses on ranking in link-based search results, AI Visibility focuses on whether your content is extractable, structured, and accessible to large language models and their training pipelines.

Why it matters

As users increasingly rely on AI assistants (ChatGPT, Claude, Perplexity, Google AI Overviews) for answers, websites that are invisible to AI crawlers lose a growing traffic channel. If an AI can't crawl your page, can't parse your content, or gets a JavaScript shell instead of real text — your brand doesn't exist in AI-generated answers.

How SEODiff measures it

SEODiff computes an AI Readiness Score (0–100) as a weighted composite of five core subscores:

• Bot Access (30%) — Are AI crawlers allowed to access your pages via robots.txt?
• Rendering (25%) — Is your content server-rendered, or is it trapped in JavaScript that AI crawlers can't execute?
• Structure (20%) — Does your HTML use semantic elements (lists, tables, headings) that help AI parse information?
• Schema (15%) — Do you have structured data (JSON-LD) that gives AI systems machine-readable facts?
• Tech Stack (10%) — Does your framework produce AI-friendly output by default?

Score caps

Two hard caps override the weighted score to reflect dealbreaker scenarios:

• If both GPTBot and ClaudeBot are blocked → score capped at 15.
• If a WAF / CAPTCHA challenge is detected → score capped at 10.

AI Visibility vs traditional SEO

• Traditional SEO: Optimise for Googlebot indexing, link authority, and SERP rankings.
• AI Visibility: Optimise for AI crawler access, content extractability, structured data, and training-data presence.

Both matter. AI Visibility is additive — improving it usually improves traditional SEO too, because the same signals (clear structure, fast rendering, good schema) benefit both.
