You only set this parameter when a user has actually completed a purchase.\n\nYou're interested in showing more impressions to users who have placed multiple\nitems in their shopping carts and initiated the checkout process. You also want\nto find users who have made a purchase during November and December because you\nplan to have a big sale on your site during those months.\n\nYou can describe this set of users with either of the following rules:\n\n1. Users who visited the checkout page **and** had more than one item in their cart.\n2. Users who checked out during the months of November or December.\n\nIf a user falls into either category 1 or category 2, you want to increase your\nbids in specific ad groups or campaigns by 25%.\n\nObjects\n-------\n\nTake a look at the structure of a rule-based user list. A rule-based list is\nrepresented in the Google Ads API as a\n[`rule_based_user_list`](/google-ads/api/reference/rpc/v21/UserList#rule_based_user_list).\n\nThe following diagram shows what the\n[`rule_based_user_list`](/google-ads/api/reference/rpc/v21/UserList#rule_based_user_list) for this\nuse case will look like when we're done.\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e"]]
