Hey creationcash2911, did you ever manage to find a permanent fix for this? Our CPMs are not getting lower than $250 even after spending thousands of dollars, and we are advertising in the US.
I run an e-commerce brand in the cosmetic niche. The frustrating part is that the ads themselves are performing incredibly well once people actually see them. My CTR for the sales is +10%, so clearly the creative is resonating. I've added an engagement campaign to warm up the account in hopes of building some trust signals, but the conversion campaign CPMs remain stubbornly high.
I've tried a bit of everything to isolate the issue. I've tested ABO vs CBO structures, tried fresh domains, new pixels, and entirely new ad accounts. Every time, the CPM starts off looking normal for the first $5 to $10, but the second it scales vertically or reaches the daily limit, the costs skyrocket.
I strongly suspect Meta's anti-circumvention system is flagging the account pattern or the domain itself, effectively shadowbanning the delivery with a massive penalty fee.
Did spending money on those engagement campaigns eventually normalize your CPMs, or did you have to completely separate your identity with a new Business Manager? Any insight would be hugely appreciated!
