14.5 CPM update: Android CPMs surpass iOS for the first time.

Ad rates for Android have caught up– and eclipsed– iOS for the first time ever on most ad formats. Is this the new normal?

The video is a walk-through of the data.

Part 2: May 28th, 2021

The trend of anemic iOS CPMs continues due to increased iOS 14.5 adoption and lowered advertiser spending (see a report run by Singular that reviews ad spend shifting to Android). Android, for the first time in the history of the smartphone are showing regular CPM superiority when compared to iOS.

Read below for specific ad unit details.

Note: CPMs are listed as index values, therefore swings may be exaggerated (or minimized) based on normalized fluctuations.


CPM-Index of US Banners

CPM-Index of non-US Banners

CPMs on Android banners have spiked near the end of Q2 — some of this is due to Amazon’s yearly pre-Prime-Day spike, which this year largely only benefited Android — but overall a large variety of advertisers are paying higher rates for Android in the recent weeks.


CPM-Index of US Fullscreens

CPM-Index of non-US Fullscreens

Interestingly– and strangely– we’ve seen relatively flat performance on full-screens when compared to the other units.

There was a big jump on Android CPMs for US traffic, surpassing iOS’ indexed CPM — largely driven by Facebook —  where the US for iOS remains flat and falls slightly outside of the US where Android sees consistent gains.

Impact on User CPMs & LTVs

Anecdotally we’ve isolated the CPMs & LTVs of a single iOS & Android app to demonstrate how this may affect long-term user value.

In all charts, the blue line shows users acquired in March; the grey April installers; the red line May and the green line is users acquired in June.
