Technically, any domain that originates and redirects traffic to your domain is known as a referring site. Using referral traffic, one can understand which websites are referring traffic
to a website and how have they discovered your website. Top pages on which such traffic comes on can be optimised to suit business goals accordingly. One of the easiest ways to make
money online is to refer your friends to products that you already use. That’s how most bloggers make a living. You need your own site to join “official” affiliate programs, there are many
programs that offer a referral bonus to anyone. There are numerous sites where you can get paid for referrals. Many of these will not only provide you with a unique referral link to post on
your blog or send via email, they are also linked into social media platforms like Twitter and Facebook.
