4 signals AI crawlers check
Crawlability (30 points)
Are GPTBot, ClaudeBot, and PerplexityBot allowed in your robots.txt? Is the site publicly accessible without login? Is there a sitemap?
Content Structure (35 points)
Does the page have semantic HTML, a proper meta description, Open Graph tags, JSON-LD structured data, and a language attribute?
Technical SEO (25 points)
Is there a canonical tag? Does the site use HTTPS? Does the page load in under 3 seconds? Is body content present without JavaScript?
Content Quality (10 points)
Is there enough text content for an AI to summarise? Are there internal links that help crawlers discover more of the site?
Common reasons websites are invisible to AI
AI crawlers blocked in robots.txt
-20 points penalty. Add explicit Allow rules for GPTBot, ClaudeBot, and PerplexityBot.
Content only visible with JavaScript
AI crawlers read raw HTML. If your body is empty without JS, your content is invisible.
Login or authentication required
-30 points penalty. AI systems cannot crawl pages behind a login wall.
No JSON-LD structured data
Without schema markup, AI systems have to guess what your page is about.
Missing sitemap
A sitemap at /sitemap.xml helps AI crawlers discover all your content.
Common questions
Does this work for any website?
Yes. GradeByAI crawls any publicly accessible URL — any CMS, framework, or hosting provider.
How is this different from a regular SEO audit?
Traditional SEO audits optimise for Google. GradeByAI focuses on what AI crawlers specifically need: robots.txt permissions, machine-readable HTML, and JSON-LD structured data.
What score should I be aiming for?
80 or above is considered AI-optimised. Below 50 means there are critical blockers preventing AI systems from reading your content at all.
