Comparison

AEO vs SEO — what's the difference?

SEO gets pages ranked so users click. AEO gets brands named in AI answers so users don't need to click. Both matter; they require different work — and they reinforce each other when done together.

Where they overlap — the foundation is shared

A strong SEO foundation is not optional for AEO — it's a prerequisite. AI systems use many of the same crawling and parsing mechanisms as search engines. If your site is technically weak, AI systems struggle to interpret it just as search engines do.

Crawlability — AI crawlers need the same access as search crawlers
Page speed — slow pages are deprioritised by both search and AI
Information architecture — clear structure helps both
High-quality, accurate content — both reward expertise and accuracy
Mobile readiness — required for both Google and AI ingestion
Canonical URLs — prevents duplicate indexing for both

Where AEO goes further than SEO

These are the AEO-specific signals that most SEO programmes don't cover — and where most sites have the biggest gaps:

Structured data depth

Product, Offer, FAQ, Organization, and MerchantReturnPolicy schema give AI explicit facts about what you sell, who you serve, and how to describe you. SEO benefits from schema too, but AEO is far more dependent on it.

llms.txt

A machine-readable index at your domain root that tells AI systems which pages matter and how to group them. Has no SEO equivalent — it's specifically for AI ingestion.

Answer-first content

SEO content is often written to rank for keyword clusters. AEO content is written to answer specific buyer questions in the first paragraph. The difference shows up most in FAQ pages and comparison content.

Entity consistency

AI systems build your brand's 'identity' from signals across your site, directory profiles, press, and review platforms. Inconsistent descriptions of your category, audience, or positioning create a confused AI picture, reducing recommendation probability.

Citation presence

AI systems retrieve and weight sources. Being listed on G2, Capterra, Product Hunt, TrustPilot, industry directories, and editorial roundups increases the likelihood that AI retrieves information about you when relevant queries are asked.

The practical approach: run both together

Don't treat AEO as a separate programme. Your SEO and AEO work compound each other when planned together:

  1. 1.Build discoverable, technically sound pages with SEO — this creates the crawlable foundation AI systems need
  2. 2.Add structured data depth (Product, FAQ, Organization schema) — benefits both Google SERP features and AI readiness
  3. 3.Create answer-first content alongside keyword-targeted content — FAQ pages and comparison content serve both audiences
  4. 4.Publish llms.txt — purely an AEO move, no SEO trade-off
  5. 5.Build citation presence on review platforms and directories — supports both domain authority (SEO) and AI mention probability (AEO)
