Google is piloting a new program for AdWords coupons. Instead of the $100 free to start, you get $300 when you spend $100. Putting a little of your own cash in the pot to see how you can make AdWords work for you.
Definitely worth a try. $100 investment in advertising, when you can practically pinpoint your audience certainly sounds like a good deal to me.
Drop me note if you’re interested in starting an AdWords campaign.
