We're getting a lot of bogus clicks from the ad display network. What's the best way to make sure our video ads only show on YouTube itself? I've added the googleadsense_without_youtube.com to the Placement exclusion list. Is there a better way? [[ edit: I'd made a mistake. Now I added this url and also our campaigns right below it, then saved. Now it seems we've been Display network free for 3 days ]] Does it help anything to export the list from 'When and where ads were showed' and exclude the worst offenders in the Display network? This is a very manual process however.
