I use Hits4Pay but there are other PTC (Pay To Click) sites that I like better. It doesn't hurt to join as many PTC websites as you can. If you are serious about making any real money by using paid to click sites then you should probably join them all. It is easy money and these sites do pay. 

I don't like that Hits4Pay needs your social security number in order to pay you. They want you to fill out a IRS W-9 tax form in order to claim your money. I have only earned $14.04 (including the $10.00 bonus) so far so I am not yet near the $25.00 minimum pay yet. Plus their ads take longer than usual...
