Comparison
AEO vs GEO vs SEO: What’s the Difference and Which Do You Need?
A side-by-side comparison of SEO, Answer Engine Optimization and Generative Engine Optimization: goals, tactics, metrics and how they work together.
The short answer
SEO earns rankings in traditional search results. AEO (Answer Engine Optimization) makes your content the direct answer extracted by engines like Google AI Overviews and chatbots. GEO (Generative Engine Optimization) increases how often AI models mention and recommend your brand. They share foundations (crawlability, quality content and authority) and work best as one strategy.

SEO: the foundation
Search Engine Optimization makes your pages discoverable, crawlable and authoritative enough to rank. Every AI search strategy depends on it: if engines can’t crawl or trust your site, they won’t quote it.
AEO: win the extracted answer
Answer Engine Optimization restructures content so a specific passage can be lifted as the answer. It’s about precision: one question, one clear answer, backed by evidence and marked up with structured data. Read the full AEO guide.
GEO: win the recommendation
Generative Engine Optimization is about the brand, not the page. Models recommend brands that are consistently described, widely corroborated and present in trusted sources. GEO combines entity work, citable content and digital PR. Read the full GEO guide.
Which one do you need?
- Your site has technical or indexing problems → start with SEO fundamentals.
- Buyers ask informational and how-to questions → prioritize AEO.
- Buyers ask AI “what’s the best…” or “X vs Y” → prioritize GEO.
- You compete in a crowded category → run all three as one program.

Frequently asked questions
Should I stop investing in SEO?
No. Google AI Overviews and many AI assistants rely heavily on pages that already rank well and are crawlable. SEO remains the foundation that AEO and GEO build on.
Which is more important, AEO or GEO?
It depends on how your buyers search. If they ask factual or how-to questions, AEO has an outsized impact. If they ask AI for recommendations and comparisons, GEO matters more. Most brands need both.
