What impressions do you pay for in your ad spend?
You’re probably using a mix of CPC and CPM bidding strategies across your campaigns. You also may begrudgingly accept that not all those ad impressions you’re paying for are genuine views of your ads, so do you know what you’re really paying for in an ad impression?
When an advert loads, or is served on a page, the advertiser is charged for that impression. But the exact nature of what’s deemed an impression differs by ad channel, and Google and Facebook have a slightly different approach.
