Another great marketplace for digital products is DealGuardian. It's not as large as Clickbank, and it can be a little confusing to beginners.

First of all, you can't even get your affiliate links from DealGuardian itself. It will just link off to the merchant's affiliate program, where you usually enter your DealGuardian ID to generate your affiliate link.

Once you do that, all activity is tracked in your DealGuardian account, including visitor stats and payments.

When searching for products, you want to take into account three things: The number of visitors, the number of sales, and the refund rate.

Compare the number of visitors and the number of sales to see if the product is selling well. Make sure that the refund rate is low, because you won't get paid for refunded purchases.

You can filter the results by clicking on the words sales, visitors, refunds, etc.
