Google has launched a trial version of Google Boost. This new service allows businesses to create online search advertising from within their Google Places account. Here's what Google has to say about the product:

Boost ads are eligible to appear in the “Sponsored Links” section of Google.com and Google Maps search result pages. For example, if you’re a restaurant owner in San Francisco who has signed up for Boost, your ad may show up when someone does a related search like the one below, indicating a cuisine and location that matches yours. Beyond the basics like your company name, address, phone number and website, your ad may also include the number of reviews you’ve received, an average star rating and a link to your Place page to help potential customers find additional useful information about your business.

The beta version is currently being trialled in San Fancisco, Houston and Chicago and if you are outside of these areas, you can sign up for notifications of when the service is available in your area by filling in an online form.
