Basically you get paid a few cents for every link you click. and visit a webpage... You get paid via paypal each Friday afternoon (if you set it up that way)... Here's some info from their site:
By creating a MeFile at YouData.com, I now control what ads I see and when I see them. Best part - I am selling my attention directly to interested advertisers, for real money. That's right, I get paid for giving them my attention. I can use the funds to buy music and video online, donate to charities, give to my favorite blogs and websites, or keep the change myself and do whatever I want with it.
Click this link to sign up. My MeFile ID, cheapsk8mom, in the "Referral Code" will tell them I sent you.
I've earned $0.15 cents this week! It's not a lot (at once) but I keep telling myself that it all adds up, and eventually I'll have a more subtantial amount of money in there... Think positive...
And - remember - they transfer your earnings into your PayPal on Fridays... so if you're already signed up - make sure you login and view your ads!!! I'm working on getting the handy-dandy widget on my sidebar so it'll be easier for EVERYONE to get their free $$$$
