Great question! CPM (Cost Per Mille) is calculated based on your total combined views across ALL your shortened links, not per individual link. So yes, if you get 1,000 unique visitors from the USA spread across multiple shortened URLs, those views will count together toward the CPM threshold. Keep in mind that the "up to $26 CPM" rate depends on factors like traffic quality, visitor location, and advertiser demand, so actual earnings may vary.
