If you're an SEO professional, you already know Screaming Frog is essential for website audits. But what you might not know is that your Screaming Frog data contains everything you need to create a perfect LLMS.txt file for AI search optimization.
This comprehensive guide will show you exactly how to convert your Screaming Frog CSV exports into professional-quality LLMS.txt files that help AI search engines understand and rank your content.
If you're new to LLMS.txt files, start with our introduction to LLMS.txt and why your website needs one before diving into this technical implementation guide.
Why Use Screaming Frog Data for LLMS.txt?
Screaming Frog provides the most comprehensive and accurate website data available to SEO professionals. When creating LLMS.txt files, you get:
- Complete page inventory: Every indexable page on your site
- Accurate titles and descriptions: Exactly what search engines see
- Proper categorization data: URL structure insights for logical organization
- Quality metrics: Word count, response codes, and indexability status
- Technical accuracy: No missed pages or broken links
1 Setting Up Your Screaming Frog Crawl
Before exporting data for LLMS.txt conversion, you need to configure Screaming Frog properly:
- Set crawl depth to capture all important pages (usually 3-5 levels)
- Enable JavaScript rendering if your site uses dynamic content
- Configure crawl limits based on your site size (remove limits for smaller sites)
- Ensure proper user-agent settings to match real crawlers
2 Exporting the Right Data
Not all Screaming Frog data is useful for LLMS.txt creation. Here's exactly what to export:
- Click the "Internal" tab in Screaming Frog
- Apply filters: Select "HTML" in the filter dropdown
- Go to File → Export → Export Current View
- Save as CSV with a descriptive filename
💡 Pro Tip
Always filter to HTML only. Including images, CSS, and JavaScript files will create noise in your LLMS.txt file and confuse AI engines.
Understanding Your CSV Export
Your Screaming Frog CSV contains dozens of columns, but only a few are crucial for LLMS.txt creation:
| Column | Purpose in LLMS.txt | Required? |
|---|---|---|
| Address | The URL for each page link | ✅ Required |
| Title 1 | Page title (may need optimization) | ✅ Required |
| Meta Description 1 | Page description (often needs enhancement) | ✅ Required |
| Status Code | Filter to 200 status only | ✅ Required |
| Indexability | Only include "Indexable" pages | ✅ Required |
| H1-1 | Backup for missing titles | ⚠️ Helpful |
| Word Count | Quality filtering | ⚠️ Helpful |
3 Data Cleaning and Preparation
Raw Screaming Frog data needs cleaning before LLMS.txt conversion:
Remove Non-Content Pages:
- Tag and category pages (if not valuable)
- Pagination pages (/page/2/, /page/3/, etc.)
- Date-based archives (/2024/01/, etc.)
- Search result pages
- Admin and system pages
Filter by Quality Metrics:
- Status Code = 200
- Indexability = "Indexable"
- Word Count > 100 (optional, for quality)
- Remove duplicate titles
Manual vs. Automated Conversion
You have several options for converting your cleaned CSV data into LLMS.txt format:
Option 1: Manual Conversion
Time Required: Several hours for a medium-sized site
Best For: Small sites or when you need complete control
⚠️ Manual Conversion Challenges
Manual conversion is time-consuming and error-prone. You'll need to categorize each page, write AI-optimized descriptions, and format everything correctly. For larger sites, this approach isn't practical.
Option 2: Automated Professional Tools
Time Required: 2-5 minutes
Best For: Professional SEO work and larger sites

Common Screaming Frog → LLMS.txt Mistakes
1. Including Too Many Pages
Not every page in your Screaming Frog crawl belongs in your LLMS.txt file. Focus on pages that provide value to users searching for your products or services.
2. Poor URL Structure Understanding
Use URL patterns to inform categorization. Pages under /services/ should generally go in a Services category, /blog/ posts in Resources, etc.
3. Ignoring Duplicate Content
Screaming Frog might capture pages with identical titles but different URLs. Choose the canonical version and remove duplicates.
4. Inadequate Description Optimization
Meta descriptions written for Google aren't always optimal for AI search engines. AI benefits from more specific, outcome-focused descriptions.
Automation and Workflow Integration
For agencies and teams managing multiple sites, consider workflow automation:
- Monthly Updates: Schedule regular Screaming Frog crawls and LLMS.txt updates
- Template Approach: Develop category templates for different industry types
- Quality Metrics: Track AI search visibility improvements after LLMS.txt implementation
- Client Reporting: Include LLMS.txt status in regular SEO reports
Measuring LLMS.txt Success
While traditional SEO metrics don't directly measure AI search performance, you can track:
- Mentions in AI search results (manual monitoring)
- Direct traffic increases (users from AI search)
- Brand search volume improvements
- Referral traffic from AI platforms
