[AMA] “Why would I want to exclude mobile app categories in Display?”

Fellow member of the list, Arnoud Adam (name shared with permission), asked:

“Why would I want to exclude mobile app categories in Display?” 

Short answer here: unless you love paying for fat-fingered clicks from Candy Crush kids, mystery placements, and apps that never convert, excluding app categories is your wallet’s best friend.

In-app advertising is notorious for irrelevant placements, fraudulent and accidental clicks, and poor engagement and conversion rates.

Don’t believe me? Read what the researchers have to say:

  1. “An Empirical Study of In-App Advertising Issues” https://arxiv.org/abs/2008.12112
  2. “Automated Ad Fraud Detection for Android Apps” https://arxiv.org/abs/1709.01213

In my experience, excluding all mobile apps can cause a drop in impressions but often results in an improvement in conversion rate / ROAS, because many app placements were low quality or non-converting.

Here’s how to exclude all Mobile App Placements from all the campaigns (including PMax and Demand Gen) in your account:
