If you’re going to email a business to ask them to add PPC, I would tell them that if they add it, we’ll list/advertise them on the business section of our new website, which is reserved for those businesses that accept ppc. That’s free advertising for them as long as they add the currency.
Seconded. There’s really no downside for business adopters. Would be great to see a simplified business tutorial that can be mailed simultaneously to business owners to explain how it works.
