The application relates to a cross-application advertisement behavior information application tracking method, device and equipment, which comprises the following steps: in response to the action of backing up cross-application advertisement behavior information, sending application action information indicating the reporting of application advertisement behavior information to a second application program; constructing a
feature vector according to the application action information and the advertisement behavior information; generating an application tracking
fingerprint corresponding to the second application program according to the
feature vector, adding the application tracking
fingerprint to the advertisement behavior information and saving the application tracking
fingerprint; backing up the advertisement behavior information with the added application tracking fingerprint to the second application program through pixel code of the second application program, and in response to the application action on the advertisement behavior information, obtaining the application action information corresponding to the application action through the application tracking fingerprint; generating a matching fingerprint for the application action according to the application action information, matching the matching fingerprint with the application tracking fingerprint, and obtaining the application tracking result of the application for the advertisement behavior information.
