YouTube is now allowing advertisers to incorporate a "Call-to-Action overlay" on their videos. With the overlay, advertisers can drive traffic to their sites where they can make purchases, sign up for email newsletters or whichever action an advertiser wishes.

The Call-to-Action overlays are available for Promoted Videos only. Promoted Videos, you may remember, are essentially the paid search of YouTube. They were once called Sponsored Videos, similar to paid search listings called Sponsored Listings.

In order to set up the overlay:

1. Set up your Promoted Video campaign like you normally would in YouTube

2. Under My Videos, go to the Video Details page

3. Fill out the fields for the Call-to-Action overlay section

You're all set. Once the campaign is in full swing, you can check YouTube Insight to see how many people are clicking on the Call-to-Action overlay.
