Abstract
Methods for tracking mobile devices with increased accuracy include generating a first time-dependent identifier. Generating the first time-dependent identifier includes device information, location information, and time information identified for the device and for a request by the device to visit a third-party content supplier in association with a redirection instruction. One or more embodiments monitor additional activity by a plurality of client devices for a second time-dependent identifier. Because both identifiers are time dependent, if the identifiers match, one or more embodiments can determine that the client device has performed an action at the third-party content supplier in association with the redirection instruction with an improved probability of accuracy.
