Developer’s GEO Implementation Checklist

Reading time: 20 minutes

TLDR

This is a comprehensive technical checklist for implementing GEO (Generative Engine Optimization) to maximize your AI visibility across ChatGPT, Claude, Gemini, and Perplexity. The checklist covers five critical areas: (1) Schema Markup (JSON-LD), (2) llms.txt standard, (3) Google Business Profile optimization, (4) Technical SEO foundation, and (5) Content optimization for AI readability. Follow this roadmap sequentially over 4-6 weeks to build a GEO foundation that compounds over time.

How to Use This Checklist

Sequential Implementation:

Weeks 1-2: Foundation (Schema + llms.txt)
Weeks 3-4: Content & Optimization
Weeks 5-6: Testing & Measurement

Progress Tracking:

Mark items as you complete them
Use validation tools to verify each section
Re-test with Surmado Signal every 60 days

Priority System:

Critical - High impact, must implement first
Important - Medium impact, implement second
Optional - Low impact, implement if time allows
