The Ultimate Checklist for GEO Optimization in 2026

Your Complete Guide to Generative Engine Optimization

Large language models cite 2-7 domains per response. Google used to show 10 blue links. That math doesn't work in your favor.

By mid-2026, over 50% of searches will end without a click. Users get their answers from AI-generated summaries on ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews. Your content either appears in those summaries, or it doesn't exist.

This checklist gives you a system: Four phases—AUDIT, OPTIMIZE, AMPLIFY, MONITOR.

What is GEO?

Generative Engine Optimization (GEO) is the practice of making your content discoverable and citable in AI-generated answers.

Key platforms:

• ChatGPT (OpenAI) - 100+ million weekly users

• Google AI Overviews - Appearing in 35%+ of US searches

• Gemini (Google) - Integrated across Google products

• Perplexity - Fast-growing AI search engine

• Claude (Anthropic) - Popular among technical audiences
