XO Communications Inc. said today that Concentric, its SMB hosting division, has added two new referral categories to its partner and referral programs.

The new categories, Affiliates and Commissioned Agents, offer competitive referral payouts, XO says.

It does not cost to sign up as an affiliate or a commissioned agent. Affiliates earn $70 for each new customer that signs up for a qualifying hosting account. Commissioned agents earn recurring monthly commissions of 10 to 35 percent of the monthly booked revenue for signed accounts, according to XO.

As a referral partner of Concentric, [participants] can be assured that they are promoting a leading hosting and e-mail service that offers unsurpassed security, performance and reliability all at an affordable price, says Barbara Branaman, vice president and general manager of XOs hosting business unit.

With the two new setups, the Concentric referral program now offers four levels of participation. The customer referral program lets existing customers refer new users and earn $50 each time a referral signs up for hosting services. someone they refer signs up for a new account. The private label reseller offer lets businesses resell hosting and e-mail services while earning ongoing revenue.
