Be careful with paid to click sites if you plan to put funds into them. Many new sites last no more than one month before closing. It is best to join well-established sites. Be wary of sites paying more then 1 cent per click. The cost of advertising will probably not cover the payment. Bear in mind that if you rent referrals, other members on the site whose clicking gives you a payment to your account, there is no guarantee of earning from them.
