  • Mobile impressions are down 13% from the start of the year, while Desktop impressions are down 11%.

  • Impact is across transaction types. Private impressions declining from 1% - 6% W/W since week 8, and Open impressions decreasing from 1% - 4% W/W.

  • Over the last 4 weeks, Mobile CPMs have continuously dropped 2% W/W.

  • Questions to consider:

    • Is this due to a change in the news cycle? 

    • Are marketers moving money out of the mobile web in preparation for a cookie-less world?

    • Is mobile inventory being perceived as less effective?
