When your ideal client has a question about performance marketing, they used to Google it. Increasingly, they ask ChatGPT, Perplexity, or Google’s AI Overviews instead. The brands that appear in those answers, cited as trusted sources, are not necessarily the ones with the best Google rankings.
That gap is what Generative Engine Optimisation is about.
AI-referred sessions jumped 527% year-over-year in the first five months of 2025. The overlap between top Google links and AI-cited sources has dropped from 70% to below 20%. Ranking on page one of Google no longer guarantees you will appear when someone asks an AI the same question. And appearing in AI answers does not require ranking on page one.
This post explains what GEO is, how it differs from traditional SEO, and the practical steps that actually move the needle in 2026.
What GEO Actually Is (and What It Is Not)
Generative Engine Optimisation is the practice of structuring your content so AI platforms cite it when generating answers to user queries.
When someone asks ChatGPT “what should I look for in a performance marketing agency?” the AI does not link to ten blue links. It synthesises an answer from multiple sources and cites the ones it found most authoritative, relevant, and easy to extract from. GEO is the work of becoming one of those sources.
It is worth being precise about what GEO is not. It is not a replacement for SEO. Strong traditional SEO, including clean technical setup, authoritative content, and backlinks from credible sources, remains the foundation. GEO adds a layer on top of that foundation specifically designed for how AI systems read, parse, and cite content.
The simplest way to understand the relationship: SEO gets you ranked. GEO gets you cited. You need both.
The Three Things AI Uses to Decide What to Cite
Based on the available research, AI citation decisions come down to three factors working together. At Coby Agency, we call this the GEO Triangle.
Relevance
Does your content directly answer the specific question being asked? AI systems break complex queries into smaller sub-questions and search for each separately. A post about “performance marketing for B2B companies” may not get cited for “how much does performance marketing cost for a small Dutch company” even if it covers the topic. Content that answers specific, narrow questions gets cited more often than content covering broad topics generally.
Authority
Does the AI trust your source? Research shows AI search has a systematic bias towards earned media, third-party authoritative sources, rather than brand-owned content. This means your own blog is not your most powerful GEO asset. Mentions in industry publications, listings on platforms like Clutch or G2, and references in LinkedIn articles all carry more weight with AI systems than a page on your own domain.
Extractability
Can the AI easily pull a clear answer from your content? Paragraph-length answers to specific questions, short sentences, comparison tables, and FAQ sections all make content easier for AI to extract and reformulate into a cited response. Long blocks of dense prose are harder to parse and less likely to be cited, even when the information is excellent.
All three factors need to be present. A post that is relevant and authoritative but poorly structured will be skipped. A post that is well-structured and relevant but from an unknown source will also be skipped. The GEO Triangle only works when all three sides are built.
How Each AI Platform Cites Differently
Not all AI platforms behave the same way, and understanding the differences helps you prioritise.
Perplexity is the most citation-transparent platform. It always shows its sources inline with direct links, prioritises recent content, and strongly favours original data and research. Getting cited by Perplexity is largely a matter of publishing specific, verifiable information with named sources and keeping it up to date.
ChatGPT Search combines training data with real-time web search. It favours comprehensive content that thoroughly addresses a topic, FAQ-style formats, and topical authority signals. Comparison articles account for 32.5% of AI citations, which directly explains why tool comparison posts perform well and why that format is worth prioritising.
Google AI Overviews benefit most from traditional SEO foundations. Pages with FAQ schema markup, HowTo schema, and clear answer-first structure are most likely to appear. Schema markup matters here more than on any other platform.
Claude, which is increasingly integrated into consumer products including Apple’s Safari, favours well-structured, logical content with clear methodologies. It synthesises rather than quotes, so content with a distinct named framework or clear step-by-step approach tends to appear more often in Claude’s responses.
Coby’s GEO Action Framework
Here are the practical steps that move the needle, in priority order.
Step 1: Write answer-first. Every H2 in every post should open with a direct 1 to 2 sentence answer to the section’s implicit question. Do not build to the answer — put it first. AI systems extract the clearest response they find, and if your answer is buried in paragraph three, it will be ignored.
Step 2: Add FAQ schema to every post with a FAQ section. Content with proper schema markup shows 30 to 40% higher visibility in AI-generated answers. FAQ schema is the single highest-ROI technical change you can make for GEO. It takes 10 minutes to add in Yoast and signals to AI systems exactly which parts of your content are question-and-answer pairs ready for extraction.
Step 3: Include specific statistics with named sources. Generic claims get ignored. Specific, verifiable data points get cited. The difference between “most B2B companies struggle with attribution” and “40 to 60% of B2B deals stall due to buying committee misalignment, according to 1827 Marketing’s 2026 research” is the difference between content that gets passed over and content that gets referenced.
Step 4: Keep content fresher than 90 days. AI platforms prefer content that is 25.7% fresher than content cited in traditional search results. Adding a “Last updated” date visibly on posts and doing quarterly refreshes of your most important pages sends a freshness signal that AI systems prioritise.
Step 5: Build earned media presence. Get Coby Agency listed on Clutch, referenced in industry round-ups, mentioned in podcast appearances, and cited in third-party articles. AI systems trust what others say about you more than what you say about yourself. Brand-owned content supports GEO, but earned media is what tips the balance.
Step 6: Check your robots.txt allows AI crawlers. If GPTBot, PerplexityBot, ClaudeBot, or Google-Extended are blocked in your robots.txt, AI systems cannot read your content and will never cite it. This is a five-minute check that many sites fail.
How to Measure GEO Performance
Traditional analytics cannot capture GEO performance. GA4 and Search Console measure what happens after a click. AI citations often drive brand awareness and recommendation without any click at all.
The practical measurement approach for 2026:
Run monthly manual audits by asking ChatGPT, Perplexity, and Google AI Overviews 10 to 15 questions your ideal client would ask. Document whether Coby Agency appears, how it is described, and which competitors appear in your place.
Track AI referral traffic in GA4 by creating a custom segment for sessions with source containing “chatgpt”, “perplexity”, “gemini”, and “claude”. This gives you a baseline that will grow over time.
Monitor your brand name in AI responses for sentiment. Being mentioned is a start. Being described accurately and positively, as “a tracking-first performance marketing agency” rather than “a Dutch digital marketing company”, is the actual goal.
The Honest Picture
One important caveat before you deprioritise your SEO work in favour of GEO: Google still sends 345 times more traffic than ChatGPT, Gemini, and Perplexity combined as of late 2025. AI traffic is growing fast but is still a small fraction of total organic traffic for most businesses.
GEO is worth investing in now because it compounds over time and the competitive window is still open. 47% of brands have no GEO strategy at all. The brands that build citation authority in 2026 will be the ones AI systems cite by default in 2028. But GEO supplements SEO — it does not replace it.
Frequently Asked Questions
What is the difference between SEO and GEO? SEO optimises content to rank in search engine results pages. GEO optimises content to be cited within AI-generated answers from platforms like ChatGPT, Perplexity, and Google AI Overviews. SEO is the foundation; GEO adds a layer designed specifically for how AI systems read and extract content. You need both, not one or the other.
Does ranking on Google help with GEO? It helps, but does not determine it. Research shows only about 10 to 20% of AI citations come from Google’s top 10 organic results. A page outside Google’s top 10 can still be cited frequently by AI platforms if it has strong authority signals, specific data points, and clear answer-first structure.
How long does GEO take to show results? Faster than traditional SEO. Adding FAQ schema, refreshing content, and restructuring posts for answer-first format can produce measurable increases in AI citation rate within four to eight weeks. Building earned media presence takes longer, typically three to six months, but that is also when the compound effects start to appear.
What content formats get cited most by AI? Comparison articles, how-to guides, and data-driven posts with specific statistics perform best. Comparison articles account for 32.5% of AI citations, making them the most frequently cited content format by a significant margin. For a performance marketing agency, posts like “Google Ads vs Meta Ads” and tool comparison posts are strong GEO assets.
Can small agencies compete with large brands on GEO? Yes. Research shows AI systems favour earned media and third-party authority rather than domain authority and budget. A small agency with a specific named framework, cited by three industry publications, can outperform a large agency with a generic blog in AI citation rate. The competitive advantage in GEO comes from specificity and third-party credibility, not scale.
