What's the real difference?
Here's the simplest way to understand it:
SEO = Optimize to appear in a list of 10 blue links.
AEO = Optimize to be the answer AI gives directly.
When you Google "best CRM for startups," SEO determines which pages appear in the results. But when Google shows an AI Overview — or when someone asks ChatGPT the same question — AEO determines which products get named in the answer.
The economics are different too. In traditional search, being #1 gives you ~30% of clicks. In AI answers, being cited gives you a direct recommendation — and those visitors convert 4.4x better because they arrive with intent validated by an AI they trust.
What SEO practices still work for AEO?
Most of traditional SEO remains essential:
- Quality content — AI engines cite content that's comprehensive, accurate, and well-written
- Page authority — 76% of AI citations come from top-10 Google results (Ahrefs)
- Technical health — Fast pages, proper indexing, mobile-friendly design
- E-E-A-T — Expertise, experience, authoritativeness, trustworthiness
- Fresh content — 95% of ChatGPT citations come from content updated in the last 10 months
Google's official stance: "No additional requirements beyond good SEO and E-E-A-T principles." They're essentially saying good SEO is the foundation.
What's new in AEO?
These are the AEO-specific optimizations that traditional SEO doesn't cover:
- Answer capsules. Short, extractable 1-2 sentence answers right after headings. SEO content tends to be conversational. AEO content front-loads the answer.
- llms.txt file. A new convention (like robots.txt but for AI models) that tells AI crawlers how to cite your content.
- AI crawler access. GPTBot, ClaudeBot, PerplexityBot — new user agents your robots.txt needs to allow.
- Question-format headings. SEO headings are keyword-focused ("Best CRM Software"). AEO headings match how people ask AI ("What is the best CRM for startups?").
- Structured citations. AI engines heavily weight content that cites external authoritative sources. Including citations boosts AI visibility by over 40%.
- FAQ schema. Dramatically more important for AEO than SEO. AI engines directly parse FAQ structured data to answer questions.
The bottom line
You don't choose between SEO and AEO. You do SEO first, then layer AEO on top:
- SEO builds your foundation — authority, content quality, technical health
- AEO makes your content extractable by AI — structure, schema, answer formatting
The sites that win in 2026 and beyond are the ones doing both. AI search isn't replacing Google — it's adding a new layer where being a search result isn't enough. You need to be the answer.
