I’ve bought many PLR products in the past through JVZoo and most of them had at least 2 upsells.
Product owners usually pay 100% commission for the front end offer, 50% for the OTO and 30% for the back end offer or high ticket offer.
Here’s one example:
Free pdf report (lead magnet)>>>E-book (front-end; 100% commission)>>>Video training (OTO; 50% commission)>>>Pack of products (back-end; 30%-50% commission)>>>Offering service (high ticket: 30% commissions)
Maybe you can model Tiffany Lambert’s affiliate program. Not sure what here affiliate program looks like, but I saw her selling 5 (400-500 words) articles for $5. And she has many PLR articles on JVZoo…Just google for her and I’m sure you will get some good ideas.
