Most "Get Paid To" Sites offer more incentives to those who refer and also to those who don`t mind doing hard clicking/reading jobs for a few extra bucks. There are some good ways to increase your number of referrals. You could place your referral link in the signature space provided in most discussion forums. Or, you could also rotate your link by paying autosurfing sites. If you are quite unsure of how to go about, simply add the referral link to the signature space provided by your mail host.. eg:. GMail/YahooMail/HotMail etc.. Good luck!
