Thank you for your helpful response — it has clarified my understanding of how to configure device targeting using the `bid_modifier` field in the CampaignCriterion.
I would like to request one additional clarification: Suppose I have already published a campaign with device targeting set to only *Computers*, by setting the `bid_modifier` to `0` for both *Mobile* and *Tablet* devices, as advised. Now, if I want to *update* this campaign to also *include Mobile devices*, could you please guide me on how to perform this update via the API? Specifically: - Should I simply increase the `bid_modifier` for Mobile devices? - If yes, what value should I set for the `bid_modifier`, considering the valid range is from `0.1` to `10.0`? How should I determine an appropriate value? - Additionally, when a user enables the Mobile device option through the Google Ads UI (for example, via an edit screen), what changes are made in the backend? What is the default `bid_modifier` value in such a case?
