Abstract

An electronic catalog system includes automated processes for detecting and handling specific types of browsing events, such as non-conversion events in which users browse but fail to purchase specific items. In one embodiment, when a user engages in a threshold level of browsing activity with respect to an item without making a purchase of that item or a substitute item, and a favorable change in the item'"'"'s state thereafter occurs (e.g., the price is reduced or the item becomes available), the user is automatically notified of the state change. In another embodiment, when a user transitions away from an item or item category after engaging in a threshold level of browsing activity, a determination is made whether to present to the user a time-limited purchase incentive that is tied to that item or item category.

Claims

1. A computer-implemented method of monitoring user browsing activity, comprising:

monitoring selections made by a user during browsing of an electronic catalog of items that are available for purchase, said items arranged in the electronic catalog in item categories;

concurrently with said monitoring, generating scores that represent levels of affinity the user has for at least one of;

(a) specific items selected by the user in the electronic catalog, and (b) specific item categories accessed by the user in the electronic catalog, each score comprising one or more values represented in a computer memory;

detecting an event in which the user discontinues browsing of an item or item category in which the user has at least a threshold level of affinity, as determined based on one or more of said scores; and

determining, in response to said event and based at least partly on an output of a pseudo-random algorithm, whether to provide to the user a time-limited purchase incentive that corresponds to the item or item category, said pseudo-random algorithm inhibiting the user from predicting whether the time-limited purchase incentive will be provided;

wherein the method, including monitoring the selections, generating the scores, detecting the event, and determining whether to provide the time-limited purchase incentive, is performed automatically by a system that comprises one or more computers.

2. The method of claim 1, wherein generating the scores comprises generating a separate score for each of a plurality of items selected by the user for viewing in the electronic catalog during said browsing.

3. The method of claim 1, wherein generating the scores comprises generating a score for a particular item when the user initially selects the item, and subsequently updating the score for the particular item substantially in real time when the user performs a subsequent action corresponding to the particular item.

4. The method of claim 1, wherein generating the scores comprises taking into consideration amounts of time spent by the user browsing the items to which the scores correspond.

5. The method of claim 1, wherein the method comprises generating a separate score for each of a plurality of item categories accessed by the user during browsing of the electronic catalog.

6. The method of claim 1, wherein generating the scores comprises generating a score for a particular item category when the user initially makes a selection corresponding to the particular item category, and subsequently updating the score for the particular item category substantially in real time when the user makes a subsequent selection corresponding to the particular item category.

7. The method of claim 1, wherein the scores are generated for item categories only, and not for specific items.

8. The method of claim 1, wherein the pseudo-random algorithm inhibits users of the electronic catalog from predicting whether a purchase incentive will be presented in response to performance of a given set of browsing events.

9. The method of claim 1, wherein generating the scores comprises updating the scores substantially in real time as the user browses the electronic catalog so that the scores cumulatively reflect the selections made by the user during said browsing.

10. The method of claim 9, wherein updating the scores comprises responding to a selection event by adjusting at least one of the scores by an amount which is dependent upon a type of said selection event.

11. The method of claim 1, wherein the method is performed in its entirety during a single browsing session of the electronic catalog.

12. The method of claim 11, further comprising causing the time-limited purchase incentive (a) to be presented to the user during the browsing session, and (b) to expire upon termination of said browsing session.

13. The method of claim 11, wherein the time-limited purchase incentive is a discount offer that is limited to an item viewed during the browsing session.

14. The method of claim 1, further comprising causing the time-limited purchase incentive to be presented in a pop-up window.

15. The method of claim 1, wherein the method is performed such that the purchase incentive is provided to the user only when the user discontinues browsing of an item category.

16. The method of claim 1, wherein the event is an event in which the user transitions from a first item category to a second item category, and the method further comprises providing the time-limited purchase incentive to the user in further response to a determination that the first and second item categories do not include any common items.

17. The method of claim 1, wherein determining whether to provide a time-limited purchase incentive to the user comprises executing the pseudo-random algorithm in response to the event.

18. A system for monitoring user browsing activity, comprising:

a computer system comprising one or more computers, said computer system programmed to at least;

monitor selections made by a user during browsing of an electronic catalog of items that are available for purchase, said items arranged in the electronic catalog in item categories;

concurrently with said monitoring, generate scores that represent levels of affinity the user has for at least one of;

(a) specific items selected by the user in the electronic catalog, and (b) specific item categories accessed by the user in the electronic catalog, each score comprising one or more values represented in a computer memory;

an event in which the user discontinues browsing of an item or item category in which the user has at least a threshold level of affinity, as determined based on one or more of said scores; and

determine, for said event and based at least partly on an output of a pseudo-random algorithm, whether to provide to the user a time-limited purchase incentive that corresponds to the item or item category, said pseudo-random algorithm inhibiting the user from predicting whether the time-limited purchase incentive will be provided.

19. The system of claim 18, wherein the computer system is programmed to generate a separate score for each of a plurality of items selected by the user for viewing in the electronic catalog during said browsing.

20. The system of claim 19, wherein the computer system is programmed to take into consideration, in generating a score for an item, an amount of time spent by the user browsing the item.

21. The system of claim 18, wherein the computer system is programmed to generate a separate score for each of a plurality of item categories accessed by the user during browsing of the electronic catalog.

22. The system of claim 18, wherein the computer system is programmed to generate a score for a particular item category when the user initially makes a selection corresponding to the particular item category, and to subsequently update the score for the particular item category substantially in real time when the user makes a subsequent selection corresponding to the particular item category.

23. The system of claim 18, wherein the computer system is programmed to update the scores substantially in real time during a browsing session so that the scores cumulatively reflect the selections made by the user during said browsing session.

24. The system of claim 18, wherein the computer system is programmed to monitor said selections, generate said scores, detect said event, and determine whether to provide said incentive, during a single browsing session of the electronic catalog.

25. The system of claim 24, wherein the computer system is programmed to cause the time-limited purchase incentive to expire upon termination of said browsing session.

26. The system of claim 24, wherein the time-limited purchase incentive is a discount offer that is limited to an item viewed during the browsing session.

27. The system of claim 18, wherein the computer system is programmed to cause the time-limited purchase incentive to be presented during a browsing session in which said event occurs.

28. The system of claim 18, wherein the event is an event in which the user transitions from a first item category to a second item category, and the computer system is programmed to take into consideration, in determining whether to provide the time-limited purchase incentive to the user, whether the first and second item categories include any common items.

29. The system of claim 18, wherein the pseudo-random algorithm inhibits users of the electronic catalog from accurately predicting whether a purchase incentive will be presented in response to performance of a given set of browsing events.

30. The system of claim 18, wherein the computer system is programmed to execute the pseudo-random algorithm in response to the event.

31. The system of claim 18, wherein the computer system comprises a web server that is responsive to requests from user computing devices by serving web pages, including web pages that include time-limited purchase incentives pseudo-randomly provided in accordance with said pseudo-random algorithm.

32. Physical computer storage comprising a computer-readable medium, said physical computer storage storing computer code that instructs a computer system to perform a method that comprises:
