Thanks for your reply, Eric. Unfortunately it isn't what I was looking for. It's clear from the API that this adds a Criterion to a Campaign. My question was: what *effect* does this have? Here's my best *guess*: Adding a CampaignCriterion (to associate a Criterion with a Campaign) has the same effect as adding an AdGroupCriterion with the same Criterion values for each AdGroup in the Campaign. Note, however, that it is not possible to create AdParam objects for a CampaignCriterion; if AdParams are needed then an AdGroupCriterion must be explicitly used. Have I got it right?
