Google has begun using its new PlusBox feature in local search results. The Local PlusBox appears as a plus sign and hotlink to a Google Map appearing after an AdWords ad in the top position at the top of the page.
When clicked, the PlusBox will expand right in the search results page, showing a map, address, driving instructions, and phone number, in addition to the location name that appears beneath the last line of ad.
The Local PlusBox will only appear on locally targeted ads. Advertisers will not be charged for clicks on the Local PlusBox, map, or driving instructions; they will only pay for clicks on their local business ad that lead to their landing page.
The Local PlusBox is being rolled out to AdWords accounts in the US, Canada, UK, and Germany.
