Patent ID: 8527350

Claim:
A computer-implemented method, comprising: identifying, by a computer, one or more advertisement events associated with an advertisement, wherein each identified advertisement event is a user interaction with the advertisement that occurs prior to a conversion event, the conversion event being a predefined user interaction with a website; selecting, by the computer, two or more time windows, each time window encompassing a period of time prior to a conversion event; determining, by the computer and for each selected time window, a corresponding time window count by determining a number of the identified advertisement events occurring within the selected time window and before a conversion event; selecting, by the computer, a weighting factor for each selected time window; generating, by the computer and for each selected time window, a weighted time window count based on a function of each of the corresponding time window counts and the weighting factor for the selected time window, the weighted time window count indicating a value of the advertisement events that occurred within the time window relative to the advertisement events occurring in the other selected time windows; and determining, by the computer, an advertisement credit for the advertisement based at least in part on the weighted time window counts-for each selected time window, the advertisement credit indicating a strength of an association between the advertisement and the conversion event.
