SiteGround is a fairly new name in the web hosting and affiliate game. They have risen quickly to be a strong contender and their services are easily sold as a strong alternative to the more commonly known hosting companies. They have a tiered affiliate program so your earnings can grow quickly if you're able to meet the sales quotas. They have no minimum payout and pay out every week! Very impressive compared to their peers. Main down-side is that you don't earn commission on domain name sales, which seems odd.
