For Google’s own AI features, GEO really is just SEO, and the data backs Google up. For ChatGPT, the assistant that sends most AI referral traffic, it isn’t: classic rankings explain only a minority of its citations. The useful position sits between the two camps: one SEO foundation, plus a small set of extra work for the platforms that don’t follow Google’s results.
What Google says
In May 2026 Google published a Search Central resource on optimising for its generative AI features, and its line has been consistent since: optimising for AI search is still SEO, and there is no separate GEO or AEO discipline needed for Google, as SEO Worth summarised after I/O 2026. Crawlable pages, clear structure and genuinely useful content are what get cited.
Where Google is right
On Google’s own surfaces, the evidence is overwhelming. A June 2026 benchmark found 93% of AI Mode citations came from pages in Google’s organic top 10, and Perplexity was close behind at 89%. If you rank well across a topic, you are already doing most of the work for AI Overviews and AI Mode. Agencies selling “GEO” for Google as something entirely new are mostly repackaging good SEO. We explain the mechanics in why AI Mode cites only top-10 pages.
Where the “it’s just SEO” line breaks
- ChatGPT plays by different rules. In the same benchmark only 30% of ChatGPT’s citations matched Google’s top 10. It leans on consensus across sources, with Wikipedia and Reddit prominent. No amount of on-page SEO creates that consensus.
- ChatGPT sends most of the AI clicks. The same report put ChatGPT at about 92% of standalone AI referral traffic. Ignoring it because Google says “it’s just SEO” leaves the biggest AI referrer to chance.
- Measurement is different. AI visibility is reported as impressions without queries or clicks in Search Console, and not at all for other assistants. That needs its own tracking routine.
- Brand is part of the job. Being named in an answer, even without a link, shapes buying decisions. Classic SEO rarely measured or managed that.
The reconciled view: one foundation, three add-ons
| Layer | What it covers | Matters most for |
|---|---|---|
| Foundation: semantic SEO | Topical coverage, entity clarity, answer-first structure, internal links | Google classic, AI Overviews, AI Mode, Perplexity |
| Add-on 1: freshness | Visible update dates, quarterly refreshes with real changes | Perplexity, agents that monitor topics |
| Add-on 2: entity consensus | Consistent brand facts, reviews, earned mentions, genuine community presence | ChatGPT, Claude |
| Add-on 3: AI measurement | Search Console AI report, referral tracking, monthly prompt tests | All platforms |
Call the add-ons GEO if you like. The point is that they sit on top of SEO, not beside it, and the foundation does most of the lifting.
GEO vs AEO vs SEO: the terms
- SEO: earning visibility in search engines. In 2026 that includes AI features inside Google.
- AEO (answer engine optimization): structuring content so systems can extract a direct answer, from featured snippets to voice and AI answers.
- GEO (generative engine optimization): earning citations and mentions in generative answers across platforms, including those that don’t use Google’s index.
In practice the three overlap heavily. If you are deciding where to spend time, start with the foundation: what is semantic SEO and how to get topical authority, then add entity consensus work for ChatGPT.
Frequently asked questions
Is GEO the same as SEO?
For Google’s AI features, largely yes: AI Mode draws most citations from pages that already rank. For ChatGPT, no: only about 30% of its citations match Google’s top 10, so entity consensus work is needed on top of SEO.
What does Google say about GEO?
Google’s position in 2026 is that optimising for its generative AI features is still SEO, and it published a Search Central resource on the topic in May 2026.
Do I need a GEO agency?
Not if your SEO is strong and covers entity building and AI measurement. Be wary of GEO offers for Google that are simply standard SEO under a new name.
What is the difference between GEO and AEO?
AEO focuses on structuring content so a direct answer can be extracted. GEO focuses on being cited or mentioned in generative answers across AI platforms. They overlap heavily.
