1. Create a short video that you want to use as an ad, say for the 5-Day Feldenkrais Discovery Challenge.
2. Upload the video to YouTube.
3. Go to adwords to decide where to place your ad. You can have it run BEFORE selected videos or on the homepage of YouTube as a sponsored result or thumbnail.
1) Automatically played before other YouTube videos
Best for driving traffic to an external website
2) Placed as a thumbnail next to related videos or on the YouTube homepage
Best for driving traffic to the ad's watch page.
Note: You have been focusing on process, not results.
