I've seen most of the big webhosts these days offer free advertising credit - often $25 Google Adwords, and $50 Microsoft Adcenter, or something similar.
What I want to know is, how do they get those deals? Do Google have a program, or do they buddy up with them? And, do they get a kick back if the customer spends more than $X? I'm particularly interested in the Google program.
I'm aware of the Google Adwords referral program where I get $5 - $40 for a customer signing up. In that deal, the customer gets nothing out of it. Is there a deal available where both the customer and I get something?
