Both In-Stream and Discovery are pay-per-view -- you pay YouTube a fixed rate for every view the ad receives -- and their return on investment (ROI) can be measured in Google AdWords. YouTube tallies one new "view" after 30 seconds of watching, or a click on the video as it's playing. If the video is less than 30 seconds, views are tallied from people who watch the entire ad.
Before you start filming video content, you’ll need to set up your YouTube channel. This can get a bit complicated. As you probably know, YouTube is owned by Google. As a result, when you sign up for a Gmail account, you’ll automatically have access to a YouTube account, a Google+ account, and much more. Depending on your business, you may not want to tie your email to your business’s YouTube channel, especially if you need to share access to the account with team members or an agency partner. We suggest that you create a common email account that can be used by multiple people.
