Google has introduced account level location extensions for ads on Google Search and Maps, an easier way to display your business location in every ad by linking your Google My Business and AdWords accounts.
Now you don’t have to set up location extensions separately for each campaign. Add business locations to a single Google My Business account and link it to AdWords and you don’t have to manually update addresses in each individual campaign.
Google launched Google My Business in June this year, allowing businesses to manage location listings to display on Google Maps, Google Search and Google+. After adding all your business locations to Google My Business and linking this account to your AdWords account, you are supposed to choose the updated location extensions from the “Extensions” tab. Google will then automatically display your business locations for all your campaigns.
You can also set up filters to assign addresses to specific campaigns. The campaign level location extensions can be used until they are completely removed by the end of the year.
