Online product subscription recommendations based on a customers failure to perform a computer-based action and a monetary value threshold

A method, comprising:

• receiving, by at least one processor coupled to memory of a server machine, a plurality of purchase requests, over a network, for a set of user accounts of an online-purchasing system hosted by the server machine;
• storing, in a database, purchase histories for the set of user accounts based on the plurality of purchase requests;
• determining, by the at least one processor, a subset of the set of user accounts of the online-purchasing system, wherein the subset of user accounts is defined based on users accounts of the subset being associated with performance of a first computer-based transaction associated with an online-purchasing resource, wherein the first computer-based transaction comprises a first online purchase or subscription;
• determining, by the at least one processor, one or more user account pairs in which one user account of the subset of user accounts performed a second computer-based transaction associated with the online-purchasing resource, wherein the second computer-based transaction comprises a second online purchase or subscription and another user account of the subset of user accounts did not perform the second computer-based transaction;
• and
• for a user account pair of the one or more user account pairs:
• determining, by the at least one processor and using the database, that a first user account of the user account pair spent a first amount of money using the online purchasing resource during a first time period, wherein the first user account is associated with performance of the second computer-based transaction;
• determining, by the at least one processor and using the database, that a second user account of the user account pair spent a second amount of money using the online purchasing resource during the first time period, wherein the second user account is associated with failure to perform the second computer-based transaction;
• determining, by the at least one processor, based on the first amount of money and the second amount of money, that the first user account and the second user account are similar accounts;
• determining, by the at least one processor, a first monetary value associated with the first user account, wherein the first monetary value is based on the performance of the second computer-based transaction during a second time period;
• determining, by the at least one processor, a second monetary value associated with the second user account, wherein the second monetary value is based on the failure to perform the second computer-based transaction during the second time period;
• determining, by the at least one processor, based on the first monetary value and the second monetary value, an impact analysis value for the second computer-based transaction representing a difference between performance of the second computer-based transaction and non-performance of the second computer-based transaction;
• determining, by the at least one processor, that the impact analysis value exceeds a threshold monetary value, thereby indicating the second computer-based transaction is a high-value action;
• generating, by the at least one processor, a graphical notification associated with the high-value action;
• sending, by the at least one processor, the graphical notification to the second user account via the network to a device associated to the second user account, wherein the graphical notification provides the device with access to an online purchase interface that allows the second user to perform the second computer-based transaction;
• and
• receiving, by the at least one processor, an indication via the network from the device associated with the second user account that the second user accessed the online purchase interface via the graphical notification.
