If you’ve heard “AEO” and “GEO” thrown around alongside SEO and aren’t sure what they actually mean, you’re not alone — these terms are new enough that even marketers mix them up. Here’s a plain-English breakdown.
SEO — Search Engine Optimization
The classic discipline: optimizing a website to rank in traditional search engine results pages (Google, Bing). It covers technical health, content quality, backlinks and user experience, aimed at earning a high position in the “ten blue links.”
AEO — Answer Engine Optimization
Optimizing content to be pulled directly into an “answer” — a featured snippet, a voice assistant response, or a direct answer box — rather than just a ranked link the user has to click. The goal is to BE the answer, not just appear near it. This matters more every year as more searches end without a click at all.
GEO — Generative Engine Optimization
Optimizing for AI tools that generate original answers by synthesizing multiple sources — ChatGPT, Gemini, Perplexity and Google’s AI Overviews. These tools don’t just rank pages; they read, summarize and cite them (sometimes). GEO is about structuring and positioning your content so these models are more likely to reference, recommend or cite your business when answering a relevant question.
How they actually overlap
In practice these aren’t three separate projects — they build on the same foundation:
- Technical SEO and genuine content quality still matter for all three; AI tools still rely heavily on well-structured, crawlable, authoritative content.
- Clear, direct, well-organized answers to real questions help both classic featured snippets (AEO) and AI-generated summaries (GEO).
- Structured data (schema markup), clear headings and factual accuracy help search engines and AI models alike understand what your page is actually about.
What this means for your strategy
You don’t need three separate budgets. You need a content and technical strategy that treats “being cited and recommended by AI” as seriously as “ranking #1 on Google” — because for a growing share of your customers, the AI answer is the only result they’ll ever see.
