Frequently asked questions
What is a good Facebook CPM? +
Most advertisers see CPMs between $5 and $15. It rises in competitive niches and during peak seasons like Q4.
How do I lower my CPM? +
Broaden your audience, improve ad relevance and engagement, test more placements, and avoid over-saturating a small audience.
Why did my CPM suddenly increase? +
CPMs rise with audience competition, narrow targeting, ad fatigue, and seasonal demand spikes such as Q4 holidays. Refreshing creative and broadening the audience often brings it back down.
Is a low CPM always good? +
Not necessarily. A cheap CPM on an irrelevant audience wastes budget. Pair CPM with engagement and conversion metrics to judge whether the impressions are valuable.
Does CPM differ between Facebook and Instagram? +
Yes. Placements price independently in the auction, and Instagram and Stories CPMs often differ from the Facebook feed, so check placement-level reports for accuracy.
