been down this road more times than i can count. in my experience, the real key is trust the numbers. CPL seems safe but you need volume to get decent CVR, and that can eat into margins quick if your offer isn't strong. SOI feels more organic, but slower to scale and sometimes more prone to deadends if your targeting isn't tight. but if you manage your funnel well and keep testing, you can get a nice steady flow. DOI is the riskiest of the three, but with the right targeting and a very aggressive follow-up, it can pump out some serious ROI fast. the problem is if you don't monitor your post-click closely, you end up with a bunch of dead leads or bad payouts. personally, i lean toward a hybrid approach: start with CPL to gather data, then shift to DOI for scale once i see what's converting. but always keep a close eye on the quality, especially on mgid, because their algorithms aren't quite as refined for intent-based campaigns as taboola's. trust the numbers, and don't be afraid to kill a poor performer fast. most folks get caught in the trap of just pushing more traffic instead of optimizing.
