Been around since 2009 means you've had so much experience in this space. I'm really considering expanding into promoting products in other niches using paid ads but my limitation is that I don't know how to speak a second language.

I agree with you that low gravity shouldn't be a criterion for selecting products to promote as there are some uncompetitive products with very low gravity. I'll like to add some characteristics of products you shouldn't promote:

1. Clickbank products that have (external) ads on their sales page
2. Products with buy buttons that do not go to the Clickbank order page
3. Products that exaggerate their promises, especially financial promises. Promises like these will lead to high refund rates (most MMO products have refund rates over 20% in fact).
4. Unresponsive vendors. Before starting to promote a product, ALWAYS contact the vendor (ask for a review copy, or ask a question about the product, or just introduce yourself). If you get no reply within 48hours do NOT promote the product.

Recently, I came across a course created by Clickbank's current #1 affiliate that claims to teach people how to drive traffic to Clickbank offers using Facebook Ads. I've seen some good reviews and positive testimonies online about the course. Here's one https://abayomioloyede.com/commission-hero-review/

What do you think about the course?
