Is GEO replacing SEO?

No — GEO is still SEO at its core. It's an additional target, AI-generated answers, built on the same technical and content foundations, not a separate discipline competing for the same budget.

Do I need to redo my SEO work for GEO?

Not from scratch — if your technical SEO (crawlability, structure, schema) is already solid, most of the GEO work is additive: answer-first content structure and citation-focused schema on top of what already exists.

How does Ripple18 measure GEO performance?

Through share-of-AI-voice tracking with Profound and Otterly.ai, and competitor benchmarking, alongside the citation and schema markup work that earns the visibility in the first place.

Should I start with SEO or GEO?

Start with SEO fundamentals if they're not already solid — GEO depends on them. If your SEO foundation is strong, add GEO to also target AI-answer citations, typically via our Growth retainer, from £3,500/month.

Comparison

GEO vs SEO

AI search and traditional search overlap more than they compete — here's the real difference, and why GEO is still SEO.

GEO (Generative Engine Optimization) and SEO are not two separate disciplines fighting for budget — GEO is still SEO at its core, built on the same fundamentals: crawlable pages, clear structure, genuine authority and structured data. The difference is the surface each one targets. SEO earns rankings in traditional search results — the links and rich results on Google, Bing and other engines. GEO earns citations inside generative AI answers — AI Overviews, ChatGPT, Perplexity and Gemini — where a well-structured, authoritative page gets quoted directly instead of just linked to. Ripple18 treats GEO as an extension of SEO work, not a replacement for it: the technical and content foundations overlap almost completely, with GEO adding answer-first structure, clean schema and share-of-voice tracking on top. SEO is available from our Starter retainer, from £1,500/month single-channel; GEO is bundled into the Growth retainer, from £3,500/month, alongside SEO and PPC.

How do they compare?

Criteria	SEO	GEO
What it targets	Traditional search results — organic rankings and rich results on Google, Bing and other search engines.	Generative AI answers — citations inside AI Overviews, ChatGPT, Perplexity and Gemini.
Core method	Technical SEO, on-page optimisation, content depth and link/authority building.	The same technical and content foundation as SEO, plus answer-first structure and clean schema built for extraction.
Cost model	Available as a single channel from our Starter retainer, from £1,500/month.	Bundled into our Growth retainer, from £3,500/month, alongside SEO and PPC.
Measurement	Rankings, organic traffic and conversions, tracked via standard SEO and analytics tooling.	Share of AI-search answers and citations, tracked with tools like Profound and Otterly.ai.
Overlap with the other	Shares its technical and content foundation almost entirely with GEO.	Can't succeed without solid SEO fundamentals underneath it — it's an extension, not a substitute.
Best for	Brands that need broad, foundational search visibility across every engine, not just AI answers.	Brands whose buyers already research via AI chat tools, who want to be the cited source.

So, where should you start?

Invest in SEO first if…

Your technical and content foundations aren't solid yet — GEO can't work without them.
You need broad visibility across traditional search, not just AI answers.

Add GEO once SEO is solid

Your SEO foundation is already in place and working.
Your buyers are researching via AI chat tools and you want to be the cited source, not just ranked.

This isn't really an either/or — GEO builds on SEO rather than replacing it. Talk to us and we'll tell you honestly whether your SEO foundation is ready for GEO yet.
