Sizemapping Enabled but No bid.size or bid.params.size set for Bidder. Here’s How To Fix It.

In order for the Placement ID’s to work with Size Mapping, you’ll need to configure the Placement IDs according to Size Map.

Troubleshooting

Step 1: Open the relevant header bidding configuration in PubGuru

Step 2: If the bidder provides multi-sized Placement IDs, request at least 1 Placement ID for every size map.

For example, AdUnit1 has 3 Size Maps:

ad unit size mapping

Request a multi-sized bidder to provide you with 3 Placement ID’s for this ad unit alone. Configure each Placement ID with the Bidder sizes that corresponds to the Size Map.

Step 3: If size is one of the parameters, in which case you will most likely get single sized Placement IDs, relevant size/s should be configured

Step 4: If an ad unit will run only on a specific device, still add other devices’ minWidths, but don’t add sizes to it.

Example 1:

A mobile unit will have the following size mapping setup:

Example 2:

A desktop/tablet unit will have the following size mapping setup:

Step 5: Save and publish
