Your ad unit has been configured for header bidding but we can’t detect the div on page. Follow these steps to fix it

There are 3 sections where an ad unit div or body tag should be implemented:

Step 1: GAM ad unit code

GAM Ad Unit


Step 2: Source code within <head> </head> or PubGuru Header Bidding configuration

Step 3: Source code, within the <body> </body>, where the ad is supposed to show


Step 1: Audit Div IDs/Slot IDs in the source code (Open the website > Right click > View Page Source)

Step 2: CTRL+F the slot ID/div ID

Off-page setup: You should see at least 1 result on the body

desktop sidebar ad unit

On-page setup: CTRL+F ‘defineslot’, to locate the header tags

search for defineslot

… then CTRL + F slot ID/div ID
If you see in your results that you have 3 matches (1 on the header, 2 on the body) then that means that the div id is set up properly.


Step 3: If it’s missing on page, verify if this unit should be part of the ad map. If not, remove it from the Header Bidding configuration. If yes, the code should be added on page.
