You may have seen a video on YouTube or some other website and wondered how to put a clickable link in a video. There are video players that you can buy that will do this for you but there's also a free service called LinkedTube which will allow you to add a clickable link to any video via Youtube so that you can post it wherever else you may be sharing your videos
First upload your video on Youtube, then go to the video page where your video is - here you will find the link which is the video ID on the end - in this case the link is http://youtu.be/poC8byzF634
We then go to LinkedTube.com with that ID and paste it into the Youtube Video field
Simply fill in the rest of the information that you're asked for and that you want your link button to display and link to.
Click “Save & Get Code” and you're there. Copy the code and paste it where you need it on your website or blog. It's an easy way to direct your visitors where you need them to go to subscribe, sign up, whatever the call to action may be.
Here's a great video from Howontheweb.com explaining it visually if you need any more help
