Despite the recent report showing that Google AdWords is getting cheaper to participate in – Google is actively developing more and more features to enhance PPC advertising for business owners. Yesterday Google announced yesterday that call extensions now support the use of local forwarding numbers – thus further localizing your ad. Local Google forwarding numbers will share the same area code as your current business phone number, or if the same area code is not available a local area code for the same geographic region will be used.
As of now this is only setup to work for US based businesses. For more information about how to setup a local forwarding number see the Google help documents.
