Clickbank is probably the most used digital marketplace for affiliate marketers. There are tons of digital products to promote.

As with all digital products, you need to be careful of what you promote. Since digital products are informational products, they are only good if they offer great information. Many ebooks and training products are low-quality, and you need to know what's inside each affiliate offer.

When it comes to digital products, you're always better off promoting a product that is popular and is already selling well. You shouldn't just look at the commission rate or the average affiliate earnings. You want a product that CONVERTS.

Why? Well, if a product is converting well, it means that you'll get more conversions too. It means that the product is filling a real need and is in demand. That product also probably has a good sales page and funnel, so you don't have to worry too much about preselling your visitors.

Fortunately, Clickbank has something called a "gravity score." This is a score that is based on how many affiliates are earning commissions from promoting this product.

The higher the gravity score, the better off you are. However, you want a gravity of score of at least six. You can filter marketplace products based on gravity score, as shown in the screenshot.

Keep in mind that six is the bare minimum, and you should ideally aim for much more than that.
