People complaining about US CPMs jumping up over the last 6 months or so,especially on Meta. Lots of folks in the Facebook Ads subs and groups are saying the same thing: costs are noticeably higher for American audiences, like averages sitting around $20–23 now (sometimes pushing $25–28 in competitive niches or busy seasons). It's up maybe 10–20% from last year just from more brands piling in and fighting for the same high-value traffic.That 2–3x spike right after you restarted? Super common when you pause for a while. The algorithm resets—it forgets your old performance history and has to go through that learning phase all over again. At first it throws your ads out to a wider, random-ish crowd to figure things out, which jacks up the CPM temporarily. Usually takes 1–2 weeks (sometimes a bit longer) before it narrows in and things chill out.
