Find a product or CPA offer with a wide general appeal like dieting, politics etc.
Go to the Google Keyword research tool and look for related keywords
Look for high search volume terms with youtube videos on the first page of the search results and bookmark the videos
Make a short video using Powerpoint or its free Openoffice alternative, which is informative, but keeps the watcher curious for more (it should MAKE him curious) and suggest more information behind a link
Upload the video under various names and respond to the videos you have bookmarked. Have an affiliate link in the description (as the first part of the description)
Rinse and repeat.
