To get more small marketers to test out AdWords Express, Google is offering a “free month” of advertising to new customers. If new advertisers sign up before December 16, Google will provide a credit in January “worth what you spend between now and the end of this year.”
However some limitations apply.
Advertisers must be new customers and not existing AdWords advertisers. AdWords Express users must spend at least $125 but the maximum credit they can receive is $125. So the offer is more like a subsidy or discount unless you carefully set your budget cap for just over $125.
I don’t have any perspective whether $125 will get anyone meaningful exposure. However my guess is that advertisers would have to spend a good deal more to be visibile during a competitive holiday season.
The offer is only valid if the advertiser billing address is in the US.
