Step 6: Check CPM rates for Managed Demand to ensure they are not inflated. Adjust them accordingly by calculating the true CPM [(UI revenue/DFP impressions)*1000].

Step 7: Has the publisher disabled header bidding? Check the status of M2HB (MonetizeMore Header Bidder) orders and line items on DFP. They have to display as ‘Ready’ or ‘Delivering’.


Step 8: Append the URL with ?googfc. Under Page Requests, you should see targeting attributes that contain ‘m2_xxxx’.

Step 9: Check the source code on multiple random pages and look for M2HB (MonetizeMore Header Bidder) script (Open the website > Right click > View Page Source).

Step 10: Search for ‘m2hb’ or ‘m2d’. You should see the on-page or off-page codes in the header.

Step 11: Audit Div IDs/Slot IDs. If any code is missing, then header bidding is disabled. Check with the publisher to confirm your findings.
