What SALT.agency does

SALT.agency is a UK-headquartered specialist SEO and AI search visibility consultancy operating under the legal entity Subpixel LTD. Founded in 2014, the firm delivers professional services across eight core offerings: Technical SEO, AI Search Optimisation, SEO Strategy, SEO Content Services, International SEO, SEO Migration Services, Enterprise Local SEO, and Travel Sector SEO & AI. The company targets global enterprise brands and high-growth SMEs across verticals including travel, finance, retail/eCommerce, manufacturing, healthcare, transport, energy, and fashion, emphasizing direct access to specialists rather than account-manager-led engagement. SALT.agency monetizes through bespoke retainer and project-based engagements, with no publicly disclosed pricing or productized tiers; revenue is generated almost entirely through professional services rather than software licensing.

The firm's technical stack centers on SEO expertise augmented by AI-driven analysis, including proprietary free tools (Mirador Local GBP Manager, GSC BigQuery SQL Hero, Hreflang Checker, Bulk Redirect Generator, Social Profile Checker) and original research publications used as content-led demand generation. SALT.agency operates three offices (London HQ, Leeds, and Boston/Hingham, MA) and supports multimodal AI search optimization across Google AI Overviews, ChatGPT, Claude, Perplexity, and Gemini. The company is recognized with the Queen's Award for Enterprise (2022) for International Trade and multiple 2024-2025 industry awards, and maintains a content-led go-to-market anchored by its blog, research publications, and "Flipping the Playbook" podcast. The firm is private, with no disclosed funding rounds, revenue figures, or institutional investors in the source data.
