What is the best way to monetize a free product?

Hi, i'm pretty new to internet marketing and i want your opinion for this one. I have a website and a product i want to give away for free because i don't think people would actually pay something for it, but i still want to make some money. Do you think the best way to do this is through a PPI network like amonetize or revenyou or is there a better way for this?

Thanks for the help!

I don't know what your product is, but you can search up way to make money from free software or open software, and adapt the recommendations to your product. Some ideas that come to mind include charging for support, documentation, upgrades, customization, etc.

It's basically a software related to a video game. Thanks for the tips!

Use a contentlocker (CPAGrip etc) or some PPI stuff.

If your software is viable and something that will definitely help people a content locker is a very viable solution, and will give you a much better return than using PPI. Content has to be very compelling though to get people to unlock it, so perhaps a video showing a walkthrough playing first that locks at the download option would work pretty well.
