I am promoting a video via AdWords and since this is my first campaign, I am wondering how long it's going to take for it to kick in? It's already been almost the entire day today but nothing seems to be moving. Any experience in that?
It will take a good number of time. Sometimes if the campaign is not good enough, then you will not good result. So, wait for the best result.
video can take couple days . 4-5 too..usually text ads goes live quickly . Or call their tech support team
Pay attention on cost control. From my experiences, advertising on YouTube can bring huge amount of clicks, with near zero conversions.
