Step 1: Audit the Div IDs/Slot IDs within the source code. To do this open the website > right click on the page > select “View Page Source”)
Step 2: Use CTRL+F to find all the mentions of “defineslot” within the code to locate the header tags (applicable if on-page)
Step 3: Use CTRL + F to find the slot ID/div ID
Step 4: Off-page setup – You should see at least 1 result on the body
Step 5: 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.
Step 6: 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 it should be included, have the publisher add the code on the page.
