Been running sweepstakes offers on and off for a bit now. Quick case: CPL got me around 15 EPC with a 40% conversion rate on a solid lander. Paid weekly, no issues. SOI, on the other hand, bumped that EPC to 25 but needed a longer funnel, and the CPA payout was a bit lower. DOI, though, is where I got impatient. Tried a few with a quick opt-in and immediate deposit push. EPC stayed low, conversions were flaky, and payout took forever. My take: CPL's faster but lower EPC, SOI's higher EPC but slower, DOI feels like a gamble unless you have a premium lander and solid retargeting. Need quick answers from anyone who's tested these across different niches what works best where and when? Got limited time and a tight budget so I need to cut through the fluff fast.
