“My first trick is simple; add a ‘card’ to the YouTube video linking to a sign up form. A card is a little icon in the top right corner that tells the viewer you have something to offer.”
Don’t worry about becoming a huge YouTube star or getting millions of views on your videos. The important thing to remember is that YouTube is a viable, and easy, way to add people to your list. Once you set it up, forget about it and let it do its job.
