Search has changed more in the past 12 months than in the previous decade combined. If you type a question into Google today, there's a good chance you'll get a generated AI answer at the top of the page — before a single traditional blue link. Welcome to the era of Generative Engine Optimisation, or GEO.
This article breaks down what GEO is, how it differs from traditional SEO, what's actually happening to organic traffic right now, and — most importantly — what you should be doing about it.
What Is GEO (Generative Engine Optimisation)?
Generative Engine Optimisation (GEO) is the practice of making your content visible and citable inside AI-generated search results. This means platforms like Google's AI Overviews, ChatGPT Search, Perplexity AI, Microsoft Copilot, and other large language model (LLM)-based discovery tools.
Traditional SEO focuses on ranking your page in a list of blue links. GEO focuses on getting your brand, content, or expertise referenced inside the AI-generated summary that now appears above those links — or inside AI chat tools that people use instead of search engines entirely.
Think of it this way: SEO gets you on the shelf. GEO gets you recommended by the AI assistant that decides what goes on the shelf.
The Hard Data: What's Happening to Organic Traffic
The numbers are hard to ignore. According to research from Semrush, when Google's AI Overviews appear on a search results page, click-through rates on the organic listings below drop by approximately 42%. AI Overviews now appear on around 13% of all Google queries, and that figure is rising.
For SEO-focused brands, this means a real reduction in traffic from informational queries — the kind of questions your blog posts used to answer and rank for. Zero-click searches are accelerating: users get the answer directly from the AI summary and never scroll down.
This doesn't mean SEO is dead. Far from it. But it does mean the strategy needs to evolve.
GEO vs. SEO: What's Different?
Here's a practical breakdown of how the two approaches differ:
- SEO optimises for ranking in blue-link results. GEO optimises for being cited or summarised inside AI-generated answers.
- SEO relies heavily on keyword density, backlinks, and page authority. GEO relies on content clarity, structured data, topical authority, and being cited by other trusted sources.
- SEO measures success via rankings and organic clicks. GEO measures success via brand mentions in AI responses, answer engine impressions, and share of voice in AI search.
- SEO is about getting people to your page. GEO is about being the source the AI trusts enough to quote.
How to Optimise for GEO in 2026
- Write for Real Questions, Not Just Keywords. AI systems are trained to understand intent, not just match keywords. Your content should answer specific, real-world questions clearly and directly. Use FAQ-style sections, clear H2/H3 structures, and get to the point fast. If someone asks 'how does X work?', your content should answer that in the first paragraph — not in paragraph seven after a long preamble.
- Build Topical Authority. AI models prefer to cite sources that demonstrate deep expertise across a topic, not just one viral article. Build out content clusters: a pillar page on your main topic, supported by detailed articles on every subtopic. This signals to both Google and AI tools that your site is a reliable reference.
- Use Structured Data & Schema Markup. Schema markup helps AI systems understand what your content is about. Add FAQ schema, Article schema, and How-To schema wherever appropriate. This increases the likelihood that your content gets pulled into AI-generated summaries.
- Earn Citations from High-Authority Sources. AI systems learn which sources to trust based on how often they're cited across the web. Invest in digital PR, guest posts, and thought leadership to get your brand and content mentioned by reputable publications.
- Keep Your Brand Presence Active on AI-Indexed Platforms. Reddit, Quora, and industry forums are now heavily indexed by AI models as signals of genuine expertise and community trust. Participate authentically in relevant conversations where your target audience is asking questions.
Should You Choose GEO or SEO?
Neither — you need both. Traditional SEO still drives significant traffic for navigational and commercial queries (e.g. 'buy running shoes' or 'best CRM software'). GEO becomes critical for informational and discovery queries ('how do I improve my conversion rate?').
The smartest strategy in 2026 is to create content that performs in both ecosystems: well-structured, authoritative, clearly written content that ranks in traditional search AND gets cited in AI-generated answers.
The Bottom Line
Brands that adapt their content strategy to the AI search era now will build a compounding advantage. Those that keep doing SEO the same way they did in 2022 will watch their organic traffic quietly disappear.
