The arrow in the EasyClick templates points to the Advertisers' Link.
This is the link you will enter inside Adwords as your final URL. Once your campaign is running the link will be visible. It's NOT visible when you just preview the video on your channel. You can instead preview your video as an ad from inside Adwords to see it with the Link in it.
To do this:
- Go to your AdWords campaign and click on the Ads tab.
- Click on the little arrow next to the video.
- Click on preview.
