Step 1: Log into tools.monetizemore.com > M2HB > Configurations
Step 2: Search for the relevant configuration
Step 3: Check the slot field in the configuration to make sure it’s correct
Step 4: Check to make sure that the slot field matches your ad unit code
Step 5: Audit the Div IDs/Slot IDs in the source code. To do this open the website > right click on the page > select “View Page Source”
Step 6: Use CTRL+F to find all the mentions of “defineslot” in the page to locate the header tags (applicable if on-page)
Step 7: Use CTRL + F to find the slot ID/div ID
Step 8: On-page setup – If you see in your results that you have 3 matches of the slot ID/div ID within the page (1 on the header, 2 on the body) then that means the div id is set up properly.
Off-page setup: You should see at least 1 result on the body
If it’s missing on the page, verify if this unit should be part of the ad map. If not, remove it from the header bidding configuration. If yes, have the publisher add the code on page.
