Harton Works

Based in Leeds, Harton Works is a small AI search and SEO agency founded in 2025 by Martin Jeffrey, a search strategist with a background working with brands including Reebok, Cadbury's, Diageo, Chelsea FC and Legoland. The agency works with businesses seeking to maintain visibility as search shifts from traditional Google rankings toward AI systems such as ChatGPT, Claude, Perplexity and Google AI Overviews. Its client work includes companies such as an electric heating business, a holiday property brand, and hospitality and retail organisations, reflecting a general commercial client base rather than a single industry focus. The agency's core methodology, which it terms Retrieval-First™ Marketing, combines conventional SEO with optimisation aimed at how AI retrieval agents select and cite sources. Services are grouped into "Visibility Engines" — covering AI search optimisation, SEO audits, content audits, and AI brand/reputation management — and "Intelligence Engines," which include AI readiness audits, growth strategy, and fractional digital strategist support. Specific techniques described include schema and structured data implementation aimed at entity clarity and factual density rather than legacy rich-result markup, content optimisation judged against whether it answers queries better than alternatives, and server log analysis to measure AI retrieval traffic separately from standard organic search reporting. The agency also publishes commentary on AI search trends and adoption through its own content channel.
