As part of The Drum’s Data Deep Dive, Cat Hartland, head of The Drum Recommends, shines a spotlight on agencies best recommended for data services.

We've compiled a list of the best agencies for data services
The Drum Recommends is a free service designed by The Drum to help marketers easily navigate and find relevant, trusted agencies, all based on their specific criteria and the ratings we receive from clients that have already worked with those agencies.
Every year, The Drum Recommends receives thousands of ratings from the clients of agencies subscribed to the service. Clients complete a survey asking them to score and comment on the agency’s overall performance, including client service, strategic thinking and effectiveness, as well as the specific services they’ve used, such as SEO or brand activation.
The unique ratings system within the platform enables us to identify agencies that come recommended for specific services and performance, which brand marketers can trust to source new agencies. In order to become recommended for these services, agencies must receive a minimum of three client ratings above a set threshold.
