Google are currently rolling out the new AdWords Local PlusBox which will now enable the top featured sponsored result in the Google search engine to display even more information.
This information will consist of a map, contact details, address and will even allow people to get directions. The best part is there is no extra charge for this and you will only billed by Google as normal, when someone clicks on your add and arrives at your landing page.
For local businesses looking specifically to target their particular geographical location this could prove very helpful in maximising the online visibility received.
