Google announced the launch of the AdWords Local Plus box. When you conduct some local searches, the sponsored listings may contain a plus sign, which you can click and expand into a map. There have been reports of this 'coming soon' but it is nowofficially live. Here are a couple screen captures:
Advertisers will not be charged for clicking on the plus sign, they will only be charged for clicks on the link that takes the searcher to the advertiser's destination.
How do you get your ads to show up like this? If you are already a local business advertiser with Google, then you won't have to do anything. The only requirement is that the ad be in the top yellow ad position, ads on the right side of the page, will not contain the plus sign.
