Dennis Lazard, Founder of ESA Digital, joins E-Coffee with Experts to unpack how search is changing as brands compete for visibility in ChatGPT, Gemini, Claude, and Google AI Overviews. Dennis traces his path from building an early AI project for Google Ads to growing an agency that works with funded and established SaaS, AI apps, and technology brands.

He shares what he learned from starting ESA Digital during the UK lockdown, winning its first client, and building the agency largely through referrals. The conversation then moves into international SEO, including multi-language testing, AI-assisted content, human rewriting, and the difference between traffic and revenue across markets.

Dennis also explains how he thinks LLMs evaluate brands: topical authority, answers to the questions people ask, brand authority, mentions, and citations. He discusses why classic SEO metrics do not yet translate neatly to LLM visibility, why reliable query-volume and click-through-rate benchmarks are still missing, and how agencies may evolve toward AI-native service-as-software platforms.
