GEO vs SEO What's actually different, and where to spend first.

Two things people say about AI search sound like they contradict each other. One: "GEO is a whole new discipline, and SEO alone won't get you into ChatGPT." Two: "GEO is just SEO with a new name."

The evidence supports a more useful middle position. Google's own guidance says AI search is still SEO. Independent citation data says AI answers regularly cite pages that don't rank on page one. Both are true, and together they tell you how to split your time and money.

This post goes through what's the same, what's different, and what to do first. If you need the basics, start with what GEO is and what AEO is. This one is about the decision.

What is the difference between GEO and SEO?

SEO is the work of getting your pages to rank in search results so people click through. GEO (generative engine optimization) is the work of getting your brand cited or named inside answers that AI tools write, in ChatGPT, Gemini, Perplexity, Google AI Mode and AI Overviews.

What does Google say about GEO vs SEO?

In May 2026 Google published a guide called Optimizing your website for generative AI features on Google Search. Its position is blunt: optimizing for generative AI search is optimizing for the search experience, "and thus still SEO."

A few specifics from the guide and Google's AI features documentation matter if you're deciding where to spend:

• No special requirements. Google says there are no additional requirements to appear in AI Overviews or AI Mode. A page needs to be indexed and eligible to show with a snippet.
• No llms.txt or special markup. The guide says Google Search doesn't use llms.txt, and that you don't need special schema.org markup.
• No chunking. You don't have to break content into tiny pieces for AI to understand it.
• Inauthentic mentions don't help. Google says seeking them isn't as helpful as it might seem, because the same ranking and spam systems apply.
• Unique content wins. It recommends a unique point of view and first-hand expertise over recycled summaries.

Two caveats. This is Google talking about Google. ChatGPT, Perplexity, Claude and Copilot have their own retrieval methods, and Google doesn't speak for them. And "no extra requirements" doesn't mean "every ranked page gets cited." It means the route in runs through ordinary SEO quality.

Do AI answers cite the pages that rank?

Often, but less reliably than most people assume. This is where GEO stops being a rename.

An Ahrefs study of 863,000 keywords and 4 million AI Overview URLs, reported by Search Engine Journal in March 2026, found that 38% of cited pages also ranked in the top 10 for the same query. Another 31.2% ranked between 11 and 100, and 31.0% ranked beyond 100 or didn't rank at all. An earlier Ahrefs study in July 2025 had put the top-10 share at 76%.

Don't take the drop at face value. Ahrefs improved how it detects citations between the two studies, so the numbers aren't directly comparable. Ahrefs also pointed to query fan-out, where an AI feature splits one question into several sub-searches and cites pages that rank for those, not for the original query. BrightEdge, using a different method, reported about 17% overlap in February 2026. Studies disagree on the size of the overlap, so treat the exact figure with caution.

The direction is clear enough for planning purposes. Ranking in the top 10 for your main keyword no longer predicts whether an AI answer will cite you. A page that answers a narrow sub-question well can be cited without ranking for the headline term.

What actually predicts AI visibility?

Ahrefs analysed 75,000 brands in 2025 and compared several factors with how often each brand appeared in AI Overviews. The strongest correlation was with branded web mentions (0.664), followed by branded anchors (0.527) and branded search volume (0.392). Referring domains (0.295) and raw backlink count (0.218) were weaker.

Ahrefs is clear that correlation isn't causation, and the study covered AI Overviews only, using brands with a Domain Rating above 40. Still, it fits what practitioners see: AI tools tend to name brands that many independent sources talk about.

That's the practical difference. Classic SEO rewards what your own pages and links say about you. GEO leans harder on what other people say about you, in places an AI can read.

Where do GEO and SEO overlap?

Most of the work is shared, which is why a separate GEO retainer rarely makes sense. The overlap:

• Crawlable, indexable pages. If a page can't be crawled, no ranking system or AI retriever will use it.
• Genuinely useful content. Original expertise, specific numbers and clear headings serve readers, rankings and AI extraction alike.
• Technical health. Fast pages, clean HTML, no duplicate content.
• Authority. Links and mentions from trusted sites help in both.
• Local and business details. A complete Google Business Profile and consistent name, address and service details feed both local rankings and AI answers about nearby providers.

Where do GEO and SEO differ in practice?

Four places justify separate attention:

1. Off-site mentions. Reviews, directory listings, industry roundups, podcasts and honest community answers. A solid SEO program often under-invests here. See how to get mentioned in ChatGPT.
2. Quotable writing. Open each section with a direct answer, back claims with named sources, and put comparisons in tables. This helps featured snippets too, so it's where AEO and GEO meet.
3. Crawler access for other AI tools. Some sites block AI crawlers by accident through a security plugin or CDN rule. Check what you're blocking and decide on purpose.
4. Measurement. Google Search Console now has a Generative AI performance report. For other tools, group AI referrals in GA4 and re-run a fixed set of buyer prompts every month. Our one-hour GEO audit walks through it.

GEO or SEO first: which should you do?

Use this as a rule of thumb.

What does it cost to do both?

Less than most people expect, if you buy them together. Because the foundation is shared, paying separately for "SEO" and "GEO" often means paying twice for the same technical and content work. A sensible split for a small business is roughly: fix and build the SEO foundation first, then spend a smaller, steady share on mentions, quotable content and AI tracking.

Our SEO packages start at $1,199 a month and include GEO and AEO work, and our guide to how much SEO costs covers typical market rates. If you want to test the economics before committing, the free SEO ROI calculator shows what organic traffic would need to be worth.

For a sense of what the SEO foundation can do, one cannabis brand we worked with went from $11,344 to $47,503 in monthly organic revenue. If you operate in that space, see our cannabis marketing agency page.

The bottom line

GEO vs SEO is a sequencing question, not a choice. SEO gets your pages found and trusted. GEO adds the work that gets you quoted and named: citable facts, a consistent brand, and mentions on other sites. Google says the first covers its own AI features. The citation data says the second covers a lot of ground the first doesn't.
