About a week ago Singular released a very interesting study ranking different traffic sources or user acquisition channels according to how much return on ad spend they bring for companies using them. Return on ad spend (ROAS) or marketing ROI has been a critical KPI for marketers in the mobile ecosystems. It allows decision makers to compare marketing activities not only by the amount of received installs but also by how much dollars were received from users who arrived through the channel and compare cost vs. return on each channel sperately.
The Singular ROI index
The study can be downloaded via this link – Singular ROI Index. It ranks the top 20 ad-networks in terms of ROAS for Android and the top 20 for iOS. It also draws some interesting insights about the differences between these two ecosystems. It finds that despite higher CPIs on iOS the ROI is 1.3x when compared to the ROI for the same app on Android running via the same ad-network. This is partially due to higher average payout on iOS.
What about Ad Revenue
The report is lacking in one aspect – it only accounts for In App Purchase revenues for ROAS calculation. A more complete view on ROAS today would consider 3 elements for each channel:
- Cost for that media channel
- IAP revenue made by users who came through the channel
- Ad revenue generated by users who came through that channel
Factoring in the ad-revenue generated from in-app ads in the ROAS calculation is becoming more and more important as the change in the mobile monetization landscape continues. This means that ad-networks who bring users who don’t convert to payers but do convert into ad-whales are under indexed in Singular’s report and networks who brings users who convert to payers but don’t contribute any ad-revenue are over indexed in the report.
Your own ROAS should also consider ad revenue
If you are using Singular for calculating your own ROAS, your decisions may be subject to the same measurement errors. Fortunately, there are already solutions for attributing ad revenue and completing your ROAS picture such as SOOMLA TRACEBACK consider using them and connecting them to Singular.
