Is data collection at the campaign or account level? Say for example, I’m using maximise clicks as the starting bid strategy for a campaign, have had around 5 conversions at the campaign level and 30 at the account level(including all campaigns), now to shift to maximise conversions' bidding, can I just edit the campaign’s bid strategy or should I create a new campaign with the new bid strategy? I do know that both of these can be done but would like to know what's best?
