Google has started its new advertising vehicle for local business called Google Tags. The service adds a yellow marker to your business listing on Google Maps plus it adds a line under your text listing. Both can link to a special offer coupon or your website.
Your tag can link to photos, videos, menus, or appointment creation pages of your website. It is an easy way to directly integrate
your business into the Google search world.
The extra brightly colored tag can make your business stand out on the map and text listing. The ability to create limited time offer coupons can help drive business to your company by adding a sense of urgency to the transaction.
Google Tags may be one easy way for small main street businesses to transition from paper advertising like the various “Yellow” books to the world of on line advertising.
If you have a verified listing in Google Places, 
you can quickly add the tag feature to your listing. Having a tag associated with your company will not improve your listing position, so you still need to work to get to the top of the local listings.
The cost for the new Google Tags service is $25 per month with the first month free if you sign up by July 23, 2010.
