AEO vs SEO: what's the difference?
The short version: SEO optimizes to rank a link on a results page; AEO optimizes to be named and cited inside the AI's answer. They overlap on technical foundations, but the goal — and several of the levers — are different. AEO doesn't replace SEO; it extends it for a world where the answer often arrives before the click.
| Dimension | SEO | AEO |
|---|---|---|
| Goal | Rank in the ten blue links | Be mentioned & cited in the AI answer |
| Surface | Search results page | ChatGPT, Gemini/AI Overviews, Perplexity, Claude, Grok |
| Unit of competition | Keyword → page position | Buyer question → share of citations |
| Winning content | Comprehensive, keyword-aligned pages | Direct-answer, evidence-dense, easily-liftable passages |
| Biggest off-site lever | Backlinks | Reddit, Wikidata, G2/Capterra, YouTube, "best-of" lists |
| How you measure | Rankings, impressions, CTR | Mention rate, citation share, share of voice across engines |
What they share
AI answer engines retrieve from live search indexes, so the technical SEO basics still gate everything: crawlability, indexability, HTTPS, mobile/viewport, valid schema, fast Core Web Vitals. If Google can't index you, AI Overviews won't cite you. More on how AEO works →
Where they diverge
- Answer-first structure — AEO rewards a crisp, quotable answer at the top of the page; classic SEO tolerated long intros.
- Evidence density — sourced statistics and citations are the strongest signal for being cited, beyond ranking.
- Entity clarity — engines need to verify who you are (Organization schema,
sameAs, Wikidata) to recommend you by name. - Community & review authority — much of what AI recommends is shaped on Reddit and review sites, not your domain.
Should you do both?
Yes. Keep your SEO foundations; layer AEO on top to win the answer. AEOX focuses purely on the AEO layer — measuring your visibility across engines, fixing the citability levers on your live site, and proving the lift — without turning into a keyword-ranking tool. AEO glossary →
