WEMF Prediction Accuracy Check
Once again, we have had our audience predictions for digital campaigns reviewed and certified by WEMF. The results confirm the high quality of our targeting solution and underline our commitment to transparency and reliable online targeting.
Anyone booking advertising on online platforms depends on their ads reaching the right target audiences. This requires predictions about the users of these platforms. These predictions enable campaigns to be delivered to specific target groups. The Prediction Accuracy Check (PAC) by WEMF reviews the online targeting predictions of publishers and media marketers and compares the results with WEMF survey data. This ensures that the predictions are complete, reliable and as accurate as possible.

Companies participating in the BPI can demonstrate that their predictions meet high quality standards and have been verified by an independent, neutral organisation.
