Html knowledge and marketing

Do we need html (HyperText Markup Language)skills in order to be a better affiliate? The answer is yes. Why? From my experience, most money made from clickbank came from some special knowledge in java script and making websites. Such knowlege did not came from ebooks or websites, but simply from traid and error. But if you dont know html, you can still make good money by many marketing methods. If possible, learn some html , and you will see the difference.

Common mistake in building clickbank affiliate links

This is a common mistake and I found many affiliate are still making it . I found this mistake in youtube videos promoting clickbank products. I found this mistake in email sent by affilaite.

Guess what? Many affiliate promote the affiliate like this: http://venderwebsitename.com?hop=affiliate-id. You will not make a cent even people buy from this link, because the buyer's browser will not have the cookie of you affiliate id. You are simply making money for vender only.
The correct link format should be : http://affiliate-id.vendr-id.hop.clickbank.net or using the hop link builder inside clickbank
