For the past decade, search engine optimisation meant one thing: get your pages ranking on Google. Build backlinks, optimise for keywords, improve your Core Web Vitals. The fundamentals haven't changed, but the game has.
Generative Engine Optimisation (GEO) is the discipline of getting your brand's content surfaced, cited, and synthesised by AI-powered search engines — ChatGPT, Perplexity, Google AI Overviews, and Bing Copilot. It's not a replacement for SEO. It's a new layer that sits on top of it, and increasingly, it determines whether your brand exists at the top of the funnel.
What Is GEO?
GEO — also called AEO (Answer Engine Optimisation) — refers to the practices that increase the likelihood that AI-generated answers will include your brand, your content, or your perspective.
When a user asks Perplexity "what's the best approach for scaling D2C on Shopify," they don't see ten blue links. They see a synthesised answer, sourced from several domains. The domains that get cited earn visibility. The ones that don't may rank perfectly well on Google, and still be invisible in the most-used AI surface for that query.
GEO is the practice of earning those citations.
How AI Search Differs From Traditional Search
Traditional search engines rank individual pages. AI search engines synthesise answers. This fundamentally changes what "winning" looks like:
- SEO win: Your page ranks #1 for "best Shopify agency." Users click through and read your page.
- GEO win: When a user asks an AI "which agency should I use for a premium Shopify build," your brand name appears in the synthesised answer, with context.
The citation is the new rank-one. And unlike a rank-one position that shifts with every algorithm update, a citation embedded in an AI model's training data can persist for months.
The Key Differences in Ranking Factors
Important: GEO doesn't replace your SEO investment. Brands that rank well on Google are more likely to be indexed and cited by AI models. Think of GEO as building a second layer of visibility on top of your existing organic foundation.
The signals AI models use to decide what to cite differ meaningfully from traditional SEO signals:
- Topical authority over keyword targeting — deep, consistent coverage of a subject beats optimisation for individual queries
- Content extractability over readability scores — structured content that yields a clean, quotable answer is cited more often
- Entity reputation over domain authority — AI models care about what other authoritative sources say about your brand
- Citation-worthy content over traffic-driving content — original data, definitive guides, and expert perspectives earn citations
Who Is Winning at GEO Right Now?
The brands capturing AI citations today share several characteristics. They have published dense, in-depth content on their core topics for several years. They are referenced by trade publications, industry associations, and respected third-party sources. Their content is well-structured — headings, lists, callout boxes, FAQ sections — making it easy for AI models to parse and extract answers.
They also have a clear, consistent entity presence. When ChatGPT encounters your brand name across multiple high-authority sources saying the same things, it builds confidence in that information and surfaces it accordingly.
Building Your GEO Strategy
A practical GEO strategy for a growth-stage brand looks like this:
- Audit your current AI visibility — manually check your 20 most important queries across ChatGPT, Perplexity, and Google AI Overviews
- Identify the gaps — where are competitors being cited and you aren't?
- Build topical clusters — comprehensive, interlinked content around your core subject areas
- Optimise for extraction — restructure key pages with clear H2/H3 headings, bullet points, and summary callouts
- Build entity presence — earn citations from trade publications, directories, and authoritative third-party sources
- Track and iterate — measure citation frequency monthly and adjust content priorities accordingly
The Risk of Waiting
GEO is not like paid search, where you can turn on a campaign and capture traffic immediately. It compounds over months. Brands that start now are building a citations portfolio that becomes increasingly hard for competitors to displace.
Brands that wait are starting from scratch in 18 months — when AI search will likely account for a significantly larger share of top-of-funnel queries than it does today.
