Popunders in premium geos just feel more competitive these days overall. You see waves where certain sources dry up or get stricter on delivery, and the whole dynamic shifts toward needing cleaner, more controlled delivery instead of raw volume. It’s kinda wild watching how user tolerance plays into it—back in the day you’d get away with more aggressive setups, but now even small overexposure seems to drop performance noticeably across the board. Just something I’ve picked up from running campaigns over the past year or so.

Yeah, I’ve felt that squeeze too in Tier 1 spots. What changed things for me was getting ruthless with source-level optimization—after a day or two of testing, I whitelist the solid publishers and cut the rest quick, which lets me push harder on the good stuff without wasting spend. Frequency caps at like one impression per user per day seem to work best now; anything looser just leads to fatigue and crappier metrics. It’s slower to ramp up than before, but once you hit profitable placements, scaling feels cleaner. Check out https://www.allydigitalllc.com/ if you’re hunting for platforms that make those source tweaks and caps easier to manage—personally I like how it gives clear breakdowns so you aren’t guessing. Still, it’s all trial and error, but tightening things up definitely saved me from a few budget disasters.
