I believe if you can get enough articles out there on the internet you can use them to really influence the payment you receive from Clickbank, and have no cash outflow for advertising.
Article Submission is great for this because.
You get a whole page to write and convince people to go to the landing page as opposed to 3 lines tops at Google Adwords.
They are free to submit.
People do read articles, regardless of what you think. They are a huge source of traffic for many webmasters. If you get an article that gets published on a high traffic BLOG you are looking at tons of click throughs.
