People keep asking about SEO, AIO, AEO, and GEO.
They sound similar, but they are not the same thing.
Here’s the simplest way to understand the difference.
SEO
Search Engine Optimization
This is about helping your content rank in traditional search results.
Think Google links, blog posts, product pages, keywords, and backlinks.
Goal: get someone to click your website.
AEO
Answer Engine Optimization
This is about helping your content be selected as a direct answer.
Think featured snippets, “People Also Ask,” voice search, and AI summaries.
Goal: get your content quoted as the answer.
AIO
AI Optimization
This is about helping large language models understand and trust your
content.
Think ChatGPT, Gemini, Perplexity, Claude.
Clear structure, clean explanations, authority, and context matter more than
keywords.
Goal: get your content referenced, summarized, or cited by AI.
GEO
Generative Engine Optimization
This is the newest layer.
It focuses on how generative AI systems assemble answers from multiple
sources.
Your content must be modular, factual, and easy to remix without distortion.
Goal: influence how AI builds responses, not just what it ranks.
The big shift most people miss:
Search is no longer just about clicks.
It’s about visibility inside AI-generated answers.
SEO gets you found.
AEO gets you quoted.
AIO gets you understood.
GEO gets you included in the story AI tells.
If you’re only doing SEO in 2025, you’re only playing part of the game.
