The question echoes across UK boardrooms, marketing departments, and business forums: is Search Engine Optimisation (SEO) dead? The rise of Generative Engine Optimisation (GEO), powered by large language models like ChatGPT and Perplexity, alongside Google’s AI Overviews, has fundamentally changed how people search for information online. But declaring SEO dead misses the bigger picture entirely. Traditional SEO hasn’t disappeared – it has transformed into something more sophisticated, more nuanced, and frankly, more strategic. The businesses thriving in this new landscape aren’t those abandoning SEO altogether; they’re the ones who’ve recognised that search strategy in 2026 requires a dual approach: optimising for both traditional search engines and the emerging generation of AI-powered generative search results.

The methodology was clear: identify what people searched for, create content around those keywords, earn links from authoritative sources, and climb the search rankings. This approach worked remarkably well for nearly twenty years, generating billions of pounds in business value for UK companies across every sector imaginable.

When someone uses ChatGPT or Perplexity to find information, they’re not entering a search query and clicking through to websites – they’re asking a conversational question and receiving synthesised answers drawn from multiple sources. Google’s AI Overviews take this a step further, embedding AI-generated summaries directly within traditional search results. This represents a fundamental shift in how search works, moving from link-based ranking systems to source attribution and relevance within AI-generated content.
The distinction between traditional SEO and Generative Engine Optimisation is not merely semantic. Traditional SEO asks:
