When users search for information, Google and AI assistants like ChatGPT and Perplexity answer the question directly — often without the user clicking a single link. The source being cited in that answer is the business that wins. Traditional SEO is built to get you ranked on a results page. GEO is built to get you cited inside the answer.
If you have been hearing both terms and wondering which one your business needs — or what the actual difference is — this guide explains it clearly, with no jargon.

What Is SEO?
SEO stands for Search Engine Optimisation. It is the practice of improving your website and online presence so that search engines — primarily Google — rank your pages higher in their results. Traditional SEO works through three main levers: making your site technically accessible to search crawlers, building content that matches what users are searching for, and earning backlinks from other websites that signal your authority and trustworthiness.
What Is GEO?
GEO stands for Generative Engine Optimisation. It is the practice of making your content discoverable, extractable, and citable by AI-powered systems — including Google AI Overviews, ChatGPT, Perplexity, Gemini, and Copilot. When someone asks ChatGPT "what is the best GMB agency in London?" or Google generates an AI Overview summarising the top local businesses in a category, the brands cited in those responses are winning a form of visibility that exists above traditional search results.
GEO is also referred to as AEO (Answer Engine Optimisation) or LLMO (Large Language Model Optimisation). These terms describe the same core objective: getting AI systems to recognise, trust, and cite your content or brand.
The Key Differences Between GEO and SEO
What They Are Optimising For
SEO optimises for rankings. GEO optimises for citations. A business can rank on page one in traditional search and still be completely absent from AI-generated answers. A business with lower traditional rankings can appear in AI answers if its content is structured more extractably.
What Signals Matter
SEO prioritises technical crawlability, keyword relevance, backlink authority, and page experience. GEO prioritises content structure, authority signals (citations, expert attribution, statistics with sources), schema markup, and third-party presence.
How Success Is Measured
SEO success is measured by ranking position, organic traffic, and click-through rate. GEO success is measured by citation frequency across AI platforms, share of AI voice versus competitors, and referral traffic from AI search engines like Perplexity.
GEO vs SEO Comparison Table
Why GEO Has Become Urgent in 2026
Google AI Overviews now appear in approximately 45 percent of all Google searches, sitting above every traditional organic result. Research shows that click-through rates to traditional organic results drop by up to 58 percent when an AI Overview is present. The businesses benefiting from this shift are those whose content is structured clearly enough to be cited inside the AI answer.
The competitive opportunity is significant. Most businesses — including your direct competitors — have not begun GEO optimisation. For tools to measure your GEO performance, read our guides on free GEO tools in 2026 and the best paid GEO tools in 2026.
Does Traditional SEO Still Matter?
Yes — significantly. GEO does not replace SEO; it builds on top of it. AI systems draw heavily from pages that rank well in traditional search. Strong traditional SEO creates the foundation that GEO needs to perform. Content that ranks well and is structured for AI extractability will outperform either approach alone.
Which One Does Your Business Need?
The honest answer is: both, in the right order. If your website has significant technical SEO problems, fix those first. If your website is technically sound with existing organic rankings, adding GEO is the highest-leverage next step. If starting from scratch, build both simultaneously.

Is GEO replacing SEO?
No. GEO is an additional layer built on top of SEO, not a replacement for it. Businesses that treat SEO and GEO as an integrated strategy will outperform those doing only one or the other.
How do I know if my brand is appearing in AI-generated answers?
Test manually — search your most important queries in ChatGPT (with web browsing), Perplexity, and Google (with AI Overviews enabled). For systematic tracking, tools like Otterly and Peec AI monitor this continuously. Our free GEO tools guide covers the no-cost options.
Can a small business compete with larger brands in GEO?
Yes — more easily than in traditional SEO. GEO favours content quality, structure, and authority signals over domain authority and budget. A well-structured blog post from a specialist local business can outperform a large brand's generic content in AI citations.
How long does GEO take to work?
Initial improvements in Perplexity can appear within 4 to 6 weeks of implementing foundational fixes. Google AI Overviews update more slowly. Building consistent citation authority typically takes 3 to 6 months.
What is the difference between GEO, AEO, and LLMO?
These terms describe the same core discipline with slightly different emphases. GEO focuses on generative AI search results. AEO focuses on getting direct answers extracted from your content. LLMO focuses on how language models represent your brand. Optimising for one typically optimises for all three.
