Unit defined XX times, don’t use the same Unit name more than once.

It is not recommended to define the same slot with the same ad unit name on the same page.

  • Device detection codes are possibly missing from the source code (if ON-page = Ad Manager or DFP tags are defined on page)
  • The device was probably not set in the PubGuru Header Bidding configuration (if OFF-page = tags are hosted in a secure MonetizeMore file)

Troubleshooting

OFF-page:

Step 1: Log in to tools.monetizemore.com

Step 2: Open the relevant PubGuru Header Bidding configuration/s

Step 3: Re-check “Slot” field to find any unnecessary duplicates

Step 4: Should an ad unit be added twice (i.e. responsive setup), ensure each ad unit defined in the configuration has the right device set (desktop/mobile)

ON-page:
