@John Turnham I am not an YT expert and basing my reply from just your comment. It is possible that your campaign is in the ad fatigue stage where no matter what you do, people are not clicking. Most likely cuz they have seen your ad a few times and it doesn’t appeal to them. It could also be a problem with targeting or the creative itself. If you haven’t yet, then create variations of your core creative to scale your YT campaign. Hope this info helps. Good luck with your campaigns!
