SEO vs GEO: How to Get Cited by ChatGPT, Gemini and Perplexity
Search is no longer just ten blue links. Millions of people now ask ChatGPT, Gemini and Perplexity for answers, and Google's AI Overviews often respond before anyone clicks a result. For brands, this raises a new question: it's no longer only "Do we rank?" but "Are we being cited?"
At our agency, we've watched this shift reshape client strategies over the past two years. As an SEO agency London businesses turn to for practical growth advice, we're often asked whether traditional optimisation still matters now that AI answers dominate. The short answer is yes, but it's no longer enough on its own. Here's how SEO and Generative Engine Optimisation (GEO) differ, and how to win at both.
What Is Traditional SEO?
Search engine optimisation is the practice of improving your website so it ranks higher in search results. It rests on three pillars:
Technical health: fast loading, mobile-friendly design, clean crawlability and secure hosting.Content relevance: pages that match what people search for.Authority: backlinks and brand signals that show you can be trusted.
The goal is a click. You rank, the user visits, and you convert them.
What Is GEO?
Generative Engine Optimisation focuses on making your content easy for AI systems to understand, trust and quote. Tools like ChatGPT, Gemini and Perplexity don't just list pages. They synthesise answers from multiple sources and often name those sources.
The goal here is a citation or mention. You may not get the click, but being named as a source builds visibility, credibility and brand recall at the exact moment someone is forming an opinion.
SEO vs GEO: The Key Differences
1. Output format. SEO targets a ranked list of links. GEO targets a single synthesised answer.
2. Success metric. SEO measures rankings, traffic and conversions. GEO measures citations, brand mentions and share of voice inside AI answers.
3. Content style. SEO often rewards keyword-optimised long-form pages. GEO rewards clear, direct, well-structured answers that a model can lift cleanly.
4. Trust signals. Both value authority, but AI models lean heavily on consistent, corroborated information across the web. If five reputable sources say the same thing about your brand, you're far more likely to be cited.
5. Query type. SEO has historically favoured short keywords. GEO thrives on conversational, long-tail questions like "What's the best way to improve local visibility for a small business?"
The two aren't rivals. Strong SEO is the foundation that makes GEO possible, because most AI tools draw on pages that already rank well and are easy to crawl.
How to Get Cited by ChatGPT, Gemini and Perplexity1. Answer questions directly
Open sections with a clear, concise answer in the first one or two sentences, then expand. AI models prefer content that resolves a question quickly. Think of each heading as a question and the first paragraph beneath it as the answer.
2. Build genuine topical authority
Don't publish scattered posts. Cover a subject in depth with connected content that links together. A cluster of well-researched articles on one theme signals expertise far better than one-off pieces.
3. Strengthen E-E-A-T
Experience, Expertise, Authoritativeness and Trustworthiness matter more than ever. Include author bios with real credentials, cite original data, show case studies and keep information current. Anonymous, generic content rarely gets quoted.
4. Use structured, scannable formatting
Short paragraphs, descriptive subheadings, bullet points, comparison tables and FAQ sections all make it easier for models to extract information. Add schema markup (FAQ, Article, Organisation, Review) to help machines interpret your pages.
5. Publish original insights and data
AI tools love citable facts. Original research, surveys, benchmarks and unique statistics give models something they can't get elsewhere. If you're the source of the data, you're the one being credited.
6. Be consistent across the web
Models cross-reference information. Make sure your business name, services and key claims are consistent across your website, Google Business Profile, LinkedIn, directories and industry publications. Earn mentions on reputable third-party sites, since being discussed elsewhere reinforces your credibility.
7. Keep your technical foundation solid
If AI crawlers can't access your content, they can't cite it. Check your robots.txt isn't blocking legitimate AI bots you want visibility from, keep pages fast, fix broken links and maintain a clean sitemap.
8. Refresh content regularly
Perplexity in particular favours fresh, recent sources. Update statistics, add new examples and show "last updated" dates on important pages.
How to Measure GEO Success
GEO measurement is still maturing, but you can start with simple steps:
Manually ask ChatGPT, Gemini and Perplexity questions your customers would ask, and note whether your brand appears.Track referral traffic from AI platforms in your analytics.Monitor branded search growth, which often rises when AI mentions increase.Use emerging AI-visibility tools to track citations over time.The Bottom Line
SEO gets you found by search engines. GEO gets you quoted by AI. Businesses that treat them as one connected strategy, built on technical excellence, authoritative content and consistent brand signals, will own visibility in both traditional and AI-driven search. Start by auditing your top pages, restructuring them to answer questions clearly, and building the trust signals that both Google and AI models reward.
