As nice as it is to sell products on one's own website, I wanted to try and sell some of my products in preexisting marketplaces with preexisting audiences.
I thought the perfect site for my After Effects templates was VideoHive —the most popular marketplace for this kind of product, but on my first attempt my GoPro Telmetry template (https://goprotelemetryextractor.com/#ae) was rejected. They don't usually focus on templates based on real world data, but rather on spectacular looking video effects.
On my second attempt, however, they selected my telemetry template for DJI drones!
Now I'll be able to compare performance: my own low-traffic site versus a high-traffic site where high commissions apply and where my product is just a drop in the ocean.
