Search Laboratory

Specialist data-driven performance marketing agency with strong international and multilingual search capabilities, operating as part of the Stagwell network

Search Laboratory is a performance-focused digital marketing agency headquartered in Leeds, UK, with additional offices in New York and other locations. Founded in 2005, the agency built its reputation on combining rigorous data science with paid search (PPC), SEO, programmatic advertising, and conversion rate optimization to deliver measurable results for clients. Its multilingual and international search capabilities became a particular differentiator, enabling global brands to execute localized campaigns across multiple markets and languages. In 2022, Search Laboratory was acquired by Stagwell Inc., the global marketing network founded by Mark Penn. The acquisition brought Search Laboratory into Stagwell's growing portfolio of performance marketing agencies, expanding the network's digital and data-driven capabilities in international markets. Despite the acquisition, Search Laboratory continues to operate as a distinct brand within the Stagwell ecosystem, maintaining its identity and specialist positioning in data-led performance marketing. Search Laboratory serves mid-market and enterprise clients across sectors including technology, finance, travel, and e-commerce. The agency's approach integrates advanced analytics, audience intelligence, and cross-channel media buying to optimize digital marketing investment. Its emphasis on transparency, attribution modeling, and international expertise positions it as a specialist alternative to larger generalist agencies within the competitive performance marketing landscape.
