Erm, i have been selling my PHP scripts through my website for some time, though my success has been limited to no more than $50 a month in sales if I'm lucky. If i open a clickbank account to sell PHP scripts, is it likely i will reach a wider potential audience? I guess i sort of want to know if it will be worth the $50 investment? But i'm also not really sure how the system works. I've read the website but would love to hear from people selling on there.
After you publish your product on Clickbank, you will need to find affiliates to promote it, otherwise there is no point of publishing. Also the sales page has to be good enough to sell, convince the buyer to buy. BTW the product in my signature will help you with publishing the product, finding affiliates and much more.
If you come up with PHP scripts that will help internet marketers...you would probably do very well with Clickbank. The biggest sellers on CB are people with products that sell well in the internet marketing business, but also appeal to the affiliates themselves. I would suggest learning a bit more about CB and what tools you might be able to create that would help the affiliates do their jobs easier...and make more money.
