I think faucet is for advertisement purpose, if you want to make money from it then you have to choose what kind of business that you want to build. if you are not sure about how to build a good business then may be you can create a website that have google ads that build in it. so you can earn from your website visitors activity that related to google ads such as ads view or ads click. I think it is the easiest way. few years ago I played a game that pay some amount of satoshi for every activity that I do and during the activity  I watch so many ads in it.
