best way to get faucet referrals based on my experience are :
make a blog about earn money from faucet and promote your blog through PTC, network ads, link share. If you don't have experience about making and managing blog, try 3rd party service to manage it for you. There are many cheap service out there, which have good result.
Another best way is making faucet rotator, many users here use this method to get ton of new referrals
but same like before, you need extra time and efforts to do this
Good Luck
