Zest Digital Limited

Based in Osney Mead, Oxfordshire, Zest Digital Limited is a small growth marketing agency founded in 2010, working with a team of between one and ten people. Its client base is concentrated in medical technology and equivalent technical, regulated markets, including medical devices, diagnostics, veterinary services, optical and vision care, clinical training, and regulated manufacturing. Named clients include Victrex and Invibio, The Dermatology Partnership, Adlens, and Improve International. The agency positions itself around technical products with long buying cycles, where purchasing decisions involve research and rarely happen on a first website visit. The agency's stated services fall into three areas: SEO, PPC, and consultation. SEO work covers on-page, off-page and technical optimisation, content, link-building and strategy, aimed at ranking for keywords used by customers close to a purchase decision. PPC services include paid search, display, remarketing, social ads, landing pages and strategy, targeting prospects at the point of search. The consultation offering is described as strategic input without full channel handover, delivered through growth mapping, guided workshops, SEO and PPC audits, measurement and reporting, drawing on frameworks developed since the company's founding. Zest Digital also states a guarantee of results within 90 days, structured around specific KPIs tied to a defined reporting process, and publishes articles on search and paid media topics such as Core Web Vitals and link building.
