What The Theory? Episode 1: The Truth Behind Brighton SEO & The GEO Myth

Search Theory Co-Founders David Vernon and Sarah Kavanagh pull back the curtain on the latest industry trends from Brighton SEO, exposing why the heavily marketed concept of GEO (Generative Experience Optimisation) is mostly a sales gimmick. They reveal the real reason behind mysterious organic traffic drops, the changing behaviour of modern consumers, and why the absolute basics of technical SEO still beat AI hype every single time.

David Vernon and Sarah Kavanagh are veteran search marketers and the Co-Founders of Search Theory, an agency built on transparent, data-driven strategies. With years of experience managing campaigns for leading brands across the UK, they launched What The Theory? to debunk industry myths, challenge lazy agency narratives, and help businesses find what actually moves the needle in modern search.

They explain:

1. The "GEO" hype cycle and why it’s just a repackaging of old-school long-tail SEO
2. The silent analytics mistake currently hiding up to 30% of your organic traffic
3. How LLMs actually crawl data, and why standard crawl budgets make cheap link-building useless
4. Why keyword strategies are shifting from simple queries to 120-word conversational prompts
5. The transparency crisis between brands and agencies that is quietly killing campaign performance
