I have a youtube account associated with adwords. I recently created two ad campaigns to run my videos as ads. I never set my billing, however it says that the ads are active. I cannot create a different campaign other than a video campaign without filling in billing info. So, how am I paying for the video campaigns, or are they simply not even showing.
I believe that they state, that you need to enter your billing details for your ads to show. It's impossible your ads to run if you don't enter billing details.
They will show that they are active but there should be a message telling you to enter your billing for them to go live. Saying that they are "active" means that they just aren't "paused". You still have to enter billing details to get them live.
They're probably not running until you get your billing info of your account setup. As simple as that.
