Melt Digital

Based in London, this agency has worked with enterprise-scale organic growth accounts since 2014, including furniture and homeware retailers, travel and hospitality brands, and other companies operating at scale online. Its client roster spans businesses such as Danetti, MADE.com, Expedia and The Hotel Guru, with work concentrated on technical SEO, content scaling and international expansion. The team is small, in the 1-10 range, and positions its work around both traditional search engines and newer AI-driven search platforms such as ChatGPT, Perplexity and Google AI Mode. Service lines cover Search Engine Optimisation, Generative Engine Optimisation (GEO), Ecommerce Product Optimisation, Content Strategy & Creation, AI-Powered Content, and Data Analysis & Insights. The GEO process is structured into five stages: citation benchmarking across AI chat applications, content inclusion checks to see whether large language models can retrieve and synthesise a site's content, entity optimisation to shape how brands are understood by LLMs, product and commerce optimisation for feeds and discovery, and agentic infrastructure work involving standards such as UCP, A2A, web MCP and llms.txt. The agency also builds proprietary tools, including the Keyword Universe for keyword discovery and a dashboard that tracks both Google rankings and AI chatbot citations from platforms like Gemini and ChatGPT, with flexible, pay-for-what-you-use tracking cadences and automated keyword categorisation by product type, intent and syntax.
