A fixed price for a placement over a period, regardless of impressions delivered: a homepage takeover for a day, a newsletter sponsorship, a podcast host-read. Flat fees are common where inventory is scarce and exclusive. The advertiser converts the fee to an effective CPM afterward using delivered impressions to compare it against auction-bought media.
