GEO vs SEO: What Generative Engine Optimisation Changes

On this page

The Short Version

Search is splitting into two outputs. One is the familiar list of links. The other is a written answer that mentions a few brands and sources. SEO wins the first. GEO wins the second. Most businesses now need both, which is why modern AI SEO covers them together.

What Stays the Same

• Crawlability and indexing. AI engines lean on pages that search engines can already read and rank.
• Helpful, original content. Thin rewrites do not get ranked or cited.
• Authority. Links and mentions from trusted sites still signal that you are worth trusting.
• Technical health. Speed, mobile usability and clean structure still matter.

What GEO Changes

The biggest shift is identity. An AI engine has to be confident about who you are before it recommends you. Brands with a common or shared name are especially exposed, because the engine may confuse them with someone else.

How AI Engines Pick Sources

1. Retrieve. The engine searches its index or the live web for pages relevant to the question.
2. Filter. It favours sources it can trust: established sites, clear authorship, consistent facts.
3. Extract. It pulls the passages that answer the question most directly.
4. Compose. It writes an answer and cites or names a handful of sources and brands.

Every step rewards the same things: being findable, being trustworthy, and stating your answer plainly. Our guide on getting cited by AI Overviews, ChatGPT, Perplexity and Claude walks through each platform.

Practical GEO Steps for the Next 90 Days

1. Month 1: identity. Align your schema, Google Business Profile and directory listings so name, address, phone and description match everywhere. Link official profiles with sameAs.
2. Month 1: baseline. Choose 20 to 30 prompts your customers would ask and record which brands AI engines mention today.
3. Month 2: answers. Rewrite your main service pages to open with a direct answer, then add FAQs, tables and comparisons.
4. Month 2: clusters. Publish supporting articles for each service and link them to the service page.
5. Month 3: proof. Earn mentions on directories, industry sites and publications. Publish original data others can cite.
6. Month 3: re-test. Run the same prompts again and compare against the baseline.

Common GEO Mistakes

• Writing for keywords instead of answering the actual question
• Inconsistent business details across the web, which confuses entity matching
• Blocking AI crawlers by accident in robots.txt or security settings
• Publishing many thin pages instead of a few complete ones
• Measuring only clicks, when AI answers often satisfy the user without one

How to Plan for Both

Do not split budgets into SEO and GEO silos. Build one plan: fix technical health, make your entity unambiguous, organise content into topic clusters, write answer-first pages, and earn mentions on sites AI engines trust. Track rankings and AI citations side by side, because they move together.

Frequently Asked Questions

Is GEO replacing SEO?

No. GEO depends on SEO. Most AI answers draw on pages that already rank, so losing SEO would also hurt GEO.

What does GEO stand for?

Generative engine optimisation: improving how often and how accurately generative AI engines mention and cite your brand.

Is GEO the same as AEO?

They overlap. AEO, answer engine optimisation, focuses on direct answers and featured snippets. GEO covers AI-generated answers more broadly, including entity and brand signals.

How do I measure GEO?

Pick a fixed set of prompts your customers would ask, test them regularly in ChatGPT, Perplexity, Gemini and Google AI Overviews, and record whether and how your brand appears.
