proof of performance

The term proof of performance is used in online advertising and stands for advertising success control.

Since the various forms of advertising are calculated according to different methods such as the click rate, costs per click( CPC), costs per order( CPO) or cost per sale( CPS), advertisers often demand proof of the success of the resources used. This data can be retrieved from the advertising servers or Google statistics and made available to the advertiser as proof of performance.
