This video illustrates two examples of some drawings that we had made up to help promote our Tea Tree Oil product. In addition, we offer the watcher a discount promo code to be used at the end of the video.
This is a basic strategy that may or may not work for your own promotions. It might be worth your time to test the idea out. You never know what may or may not work for you until you try.
In fact, you could take the marketing part of the video and make a separate clip. Then you would simply add the clip to videos that you subsequently make. This way you are not doing the same work over and over again.
Or, if you are outsourcing, you can save employee work hours that way. They can work on something else with the additional time.
