guys help me by telling what is a referral..??

Referral is a systematic process that maximizes word of mouth potential. Referral does this by encouraging, informing, promoting and rewarding customers and contacts to think and talk as much as possible about a company, product or service to people they know. For an example, MyLot has a referral program. You can refer your friend or someone you know to join MyLot. It is simply by giving your referral links. Whenever your friend join mylot through your referral link, you will receive a percentage of their income when they active in mylot. Hope it is helpful.
