Sandhill.many thanks for your informative post. Yes, this is how AMAZON.COM made a ton of money. They were really the first one to set up Affiliate Marketing on the internet in a big way and it has paid off handsomely. This is why GOOGLE is worth billions, because of advertising dollars. Corporations love "click thru's" advertisng because it is a lot less money than TV.etc. The more proven visitors a site has the more they get from click thru's. One of the biggest click thru companies is CLICKBANK.COM as they handle all of the set ups, billing,etc. I have a website called WWW GOODPHARMACIES.COM and only pay a small monthly fee for internet service,visitor clicks thru's etc. Have a good day.
