around 2 years ago, I published a chrome extension for responsive testing on ProductHunt, and it was a very successful launch, after that day the extension getting more users every day until the moment.
I've added a carbon ad to the extension, hoping to generate some revenue but actually, it makes 30$ at its best.
My primary goal is to keep it free while I have the motivation to keep pushing features.
So I'm writing here to find ideas to improve the extension revenue while keeping it free.
P.S: motivation = money :P .
Here's the ProductHunt launch page
