The Network Comparison report helps you identify and address discrepancies between MAX and network partners. It centralizes MAX- and network-reported data into one dashboard so you can compare stats without having to download multiple reports. The dashboard metrics include impressions, CPM, and revenue and it calculates the differences between the two platforms.
Use this report to validate that network CPMs are aligned with CPMs reported in MAX. Because network data powers Auto CPM updating and bidding, it is important that you ensure MAX is pulling in accurate information for networks competing in the unified auction so you do not lose money.
Before you use the report, connect your networks on the Networks page. From there, navigate to MAX > Mediation > Debug Reports > Network Comparison. The CPM Delta metric is a great starting point for identifying discrepancy issues. Include network placement, application, ad type, and country (if applicable) in the report filters for a granular breakdown to identify discrepancy issues.
If you don’t see your network appear in the report, try reconnecting to the network on the Networks page.
You may see higher discrepancies between network and MAX numbers at launch and when user adoption rates are low, but this should stabilize as adoption increases.
If there are discrepancies greater than 5% for one or more network placement IDs after full adoption, reach out to your account team or submit a support ticket for assistance troubleshooting.
