Submerge

Based in Hatfield, this small agency (team of 1-10, founded in 2014) works with brands seeking visibility across search, AI tools, paid media and social platforms rather than Google alone. It operates as a UK-based, SEMrush Certified Agency, positioning itself for businesses that need to be found across a fragmented discovery landscape spanning traditional search, AI assistants such as ChatGPT, social channels and paid advertising. Services are organised around four areas: strategy, foundations, growth and measurement. Strategy work covers visibility strategy, market and competitor analysis, audience and channel strategy, search and AI strategy, and digital marketing strategy. Foundations-level work addresses technical SEO, AI and LLM visibility, entity and schema optimisation, indexation and crawl optimisation, page speed and Core Web Vitals, and structured data. Growth services include SEO and organic search, content marketing, digital PR and outreach, paid social and PPC, organic social media, conversion rate optimisation, and web development. Measurement services cover analytics and tracking, attribution and measurement, reporting and dashboards, performance audits, and GA4 consultancy. The agency also publishes downloadable resources, including an SEO migration checklist, a social media calendar template and a web design price guide, alongside PPC, SEO ROI and CPA calculators, and maintains an insights section covering AI, content marketing, SEO, marketing strategy, PPC and web design topics.
