I don't like ad-based hosting for a business site. Hosting is so cheap these days. I've been with hypermart for three years, and never a problem. $10.00/month per hosted domain.
Do you really want a goodle ad for your competition to pop up on your website??
I just signed up for Google ads. I already have one gutter job out of the deal, after two days. Not bad. 27 displays, 2 clicks (one was me) and one phone call! I need to add more keywords, and maybe remove a couple, but at $0.38/click, it's not bad if the calls keeping coming to justify the expense. Good thing is they let you set a budget, so you don't wind up with a huge bill you didn't expect. I have mine set at $30.00/month for now, we'll see how that goes. Kinda neat.
