Impression – Ads

The number of times an ad is shown to people.

What are the common problems calculating ad impressions?

Basically inaccurate counts.

  • Ad Fraud: Bots generate fake impressions.
  • Ad Blockers: Ads blocked but still counted.
  • Viewability Issues: Ads load but aren’t seen.
  • Different Counting Methods: Platforms count differently.
  • Cookie Deletion: Users counted multiple times after clearing cookies.
