When to add a mobile optimization ad group to DeviceID or Microproximity campaign.
If a DeviceID (DID) or microproximity campaign is not on pace to deliver the number of ordered impressions, our team will reach out with multiple optimization options. After the optimizations have been implemented, if the campaign is still struggling with delivery, we recommend adding a mobile optimization ad group to the campaign.
A mobile optimization ad group is an additional optimization we can add to a campaign that runs on mobile and tablet devices only. This ad group will run in tandem with the active DID/microproximity ad group and will be geo-targeted to the requested geo. Any impressions not delivered to the DID/microproximity targeted ad group, will be delivered to the mobile optimization ad group.
