The invention relates to a cross-application advertisement behavior information application tracking method, device and equipment, and the method comprises the steps: responding to an action of cross-application
backup advertisement behavior information, and transmitting application action information for indicating to report the application advertisement behavior information to a second application program; constructing a
feature vector according to the application action information and the advertisement behavior information; according to the
feature vector, generating an application tracking
fingerprint corresponding to the second application program, adding the application tracking
fingerprint to the advertisement behavior information, and storing the application tracking
fingerprint; backing up the advertisement behavior information added with the application tracking fingerprint to the second application program through a pixel code of the second application program, responding to an application action of the advertisement behavior information, and obtaining application action information corresponding to the application action through the application tracking fingerprint; and generating a matching fingerprint for the application action according to the application action information, and matching the matching fingerprint with the application tracking fingerprint to obtain an application tracking result for the application of the advertisement behavior information.
