Search is changing faster than most marketing teams can keep up with. For decades, ranking on page one of Google was the goal. Today, a growing share of "search" happens inside a conversation with an AI, and the answer a user sees is often synthesised from several sources at once, with no guarantee your website gets a click, or even a mention. This is the shift that has given rise to Generative Engine Optimisation, commonly shortened to GEO.
At Pluspoint Digital, we look at GEO as the natural evolution of search optimisation rather than a replacement for it. This article breaks down what GEO actually is, why it matters right now, and how it differs from the SEO practices most teams already know.
Generative Engine Optimisation is the practice of structuring content, data, and brand presence so that AI-powered answer engines, such as ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Gemini, and Microsoft Copilot, are more likely to cite or reference your brand when generating a response to a user's query.
The term was originally coined by researchers at Princeton, whose foundational paper (presented at KDD 2024) tested a 10,000-query benchmark and found that specific content techniques could measurably increase how often a source was cited inside generative answers.
Where classic SEO optimises for a ranked position on a results page, GEO optimises for a citation inside a generated answer. The disciplines overlap heavily on fundamentals like clarity, structure, and trustworthiness, but GEO places extra weight on extractable passages, third-party validation, and statistical density.
The scale of AI-assisted search is no longer a projection, it is current, measurable behaviour:
These figures point to the same conclusion: a meaningful share of your audience's research now happens entirely inside an AI interface, and if your brand isn't structured to be cited there, you're effectively invisible for that portion of the journey.
GEO doesn't discard SEO fundamentals, it builds on them. But the ranking factors that move the needle differ in important ways:

One of the more interesting findings from the Princeton/KDD research is that GEO can level the playing field: fifth-ranked websites in a search result gained +115.1% visibility from adding source citations, while first-ranked sites actually lost visibility from the same tactic. In other words, GEO isn't just an advantage for established leaders, it's an opportunity for brands further down the traditional rankings to earn a place inside the AI-generated answer.
Based on the KDD 2024 study and more recent 2026 industry data, a few content techniques consistently outperform others:
Meanwhile, tactics that worked for traditional SEO, like keyword stuffing, actually performed worse than doing nothing in generative engine testing. This is a meaningful signal for any brand planning a GEO strategy for AI search optimisation: quality, structure, and verifiable data matter more than repetition.
It's also worth noting that a large share of AI Overview citations, by some measures over 80%, come from pages outside the traditional top 10 search results. Ranking well still helps downstream, since AI citations have been shown to lift organic click-through afterward, but ranking alone is no longer the whole game.
You may also come across the term Answer Engine Optimisation (AEO). AEO is best understood as a subset of GEO, focused specifically on structured answer surfaces like Google's featured snippets and AI Overviews. GEO is the broader discipline, covering every generative retrieval surface, from ChatGPT and Perplexity to Copilot and Gemini. Every AEO tactic qualifies as a GEO tactic, but not every GEO tactic is specific to AEO.
At Pluspoint Digital, we treat GEO SEO as an extension of a brand's existing search strategy, not a separate silo. That means auditing how a brand currently appears (or doesn't appear) across AI-powered search engines, identifying which content assets are structured well enough to be extracted and cited, and strengthening the third-party trust signals that generative engines consistently favour. As Generative search and AI search continue to reshape how people find information, our focus is on making sure our clients' brands are part of the answer, not left out of it.
What is Generative Engine Optimisation (GEO)?
Generative Engine Optimisation is the practice of structuring content and brand presence so AI-powered search tools like ChatGPT, Gemini, and Perplexity are more likely to cite your brand in their generated answers.
How is GEO different from traditional SEO?
Traditional SEO focuses on ranking a page on a search results list. GEO focuses on getting cited inside an AI-generated answer, which places more weight on extractable, statistic-rich, and well-sourced content rather than ranking signals alone.
Does GEO replace SEO?
No. GEO builds on SEO fundamentals like clarity, structure, and trustworthiness. Most brands need both an SEO optimisation strategy and a GEO strategy working together.
What content techniques improve visibility in AI search?
Research shows that adding quotations, citing credible statistics, and referencing third-party sources consistently improve how often content is cited by generative engines, while keyword stuffing tends to hurt visibility.
Can smaller or lower-ranked websites benefit from GEO?
Yes. Studies show that lower-ranked sites can see substantial visibility gains from GEO techniques like source citation, sometimes outperforming top-ranked pages that rely on older SEO tactics.
