Today Google launched a U.S. credit card that exclusively pays for AdWords campaigns.

Video production is getting cheaper, so Google is creating a self-service option for pre-roll advertisements aimed at small- and medium-sized businesses.

Three years ago, only 54% of small businesses had websites. Now 82% do. But lots of them have no idea how to use Google's most valuable ad tool. So the search giant is launching a slew of services and products to make AdWords easier.

"Osama Bin Laden" was tops in Google search yesterday. But not in search advertising, where not a single seller stepped into the void.

Conscious that its systems sometimes contain ads to illicit services, Google is tightening up its policies.

What one small business learned about online advertising, and the lessons that may pertain to your company.

We have AdGrok to thank for that. The Y Combinator alum is dedicated to making AdWords user-friendly.
