Categories and URLs with Cookie ID's tied to MAIDs, 500 million+ daily records. Datastream Groups’ online data covers US and International web requests. We process over 500 million consumer records every day, which have MAIDs linked to them. With MAIDs as identifiers, our clients can get a crystal-clear view of how consumers are interacting with their brand regardless of what platform from which they log on. If you’re thinking the concept of MAIDs sound an awful lot like cookies, it’s because it is. Like cookies, MAIDs can be used to track a consumer’s activity on the web. This data can then be used to serve up relevant content — like display ads — in the right place, and at the right time. The difference between the two, however, is that cookies don’t work across multiple devices. And, in a world where the average technology user carries 2.9 devices at all times, tracking only desktop activity simply won’t cut it. MAIDs, on the other hand, can be used to track cross-device activity. While I don’t think we’ll be ruling out cookies any time soon, MAIDs are a great complement to cookie tracking.
