[SAMPLE] Datastream Group Online Web Data US | Categories to Cookie to Hashed Email feed by

Categories and URLs with cookie ID's tied to Hashed emails, 200-500 million daily records.

Datastream Groups’ online data covers over 90% of all the traffic on the web. We process up to 600 million consumer records every day, many of which have hashed e-mails linked to them. With hashed emails 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 hashed emails sound an awful lot like cookies, it’s because it is. Like cookies, emails 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. Hashed emails, 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, hashed emails are a great complement to cookie tracking.
