GPTBot, ClaudeBot, and Google-Extended are crawling the web to train AI models, but most websites aren’t ready for them. Unlike Google’s search crawler, these AI bots have completely different needs—and most sites are failing their tests.
What I Built
I created an LLM Crawler Readiness Assessment Tool—a production Flask app that audits websites across 9 technical factors and shows you exactly what AI crawlers see when they visit your site.

What it does:
- 9 Technical Assessments - Checks everything from robots.txt to structured data
- AI Content Analysis - Uses Gemini to analyze your content from a crawler’s perspective
- Traffic Light Results - Simple red/yellow/green scoring anyone can understand
- Actionable Recommendations - Specific fixes for each issue found
- Production Scale - Handles thousands of audits with rate limiting and monitoring
The tool has revealed that 70% of websites have poor HTML visibility for AI crawlers, and 45% lack the structured data that helps AI understand their content.
How I Built It
I built this as a single-file Flask application deployed on Render, focusing on simplicity and reliability. The system runs 9 different checks on each URL, from basic accessibility to AI-specific signals like llms.txt files.
The architecture uses a straightforward assessment pipeline where each check returns a simple red/yellow/green status with an explanation. This makes it easy to understand results and extend with new checks as AI crawler behavior evolves.
For the AI analysis component, I integrated Google’s Gemini API to analyze the actual HTML content that crawlers see, providing insights that go beyond technical compliance.

How Does It Work
When you submit a URL, the tool runs through a comprehensive assessment:
Technical Accessibility Checks:
- Does your robots.txt allow or block AI crawlers?
- Is your site accessible without JavaScript rendering?
- Are there redirect chains that waste crawler budget?
AI-Specific Signals:
- Do you have an llms.txt file with AI crawler instructions?
- Is your structured data (JSON-LD) properly formatted?
- Are meta tags accidentally blocking AI indexing?
Content Discoverability:
- Is your sitemap helping crawlers find content?
- Do internal links create a clear site structure?
- Is your content fresh enough to warrant re-crawling?
The AI analysis then examines your actual page content, removing navigation and ads to focus on what crawlers care about—your core information and how well it’s structured for AI understanding.
