Cost Per Mille (CPM)
The cost an advertiser pays per one thousand impressions of influencer or media content.
Cost per mille, or CPM, is the price paid for one thousand impressions, where mille is Latin for thousand. You calculate it by dividing total spend by impressions, then multiplying by one thousand: a $2,000 post earning 400,000 impressions has a $5 CPM. CPM is the standard currency for comparing awareness efficiency across creators, platforms, and formats because it normalizes cost against exposure. It does not measure engagement or conversions, so a low CPM is only good if the audience is real and relevant. Pair CPM with engagement-based and conversion-based costs for a full read.
Gigde benchmarks influencer CPMs across tiers and platforms so you know whether a creator's rate is fair before you sign, a core part of how we negotiate inside Influencer Campaign Management. We model blended CPM across a roster, flag inflated rates relative to verified reach, and rebalance spend toward creators delivering efficient, authentic exposure. Because we tie CPM back to conversions, you see not just cheap impressions but valuable ones. For CPM benchmarking and rate negotiation, see /services/influencer-marketing or email contact@gigde.com.
