Google just released a new Google Places bulk upload option for businesses that have 10 or more locations and want to upload their account using a spreadsheet. Once you use the verification tool for the first ten businesses, you won’t have to go through the verification process again.
This new bulk upload option is available for all account from a link in the Google Places interface. What this tool is not, is a way to scam Google Places with fictitious addresses. You’ll get nailed on that one, so don’t waste time trying.
Although this feature is not for every business owner, it will make it easier for larger businesses to manage their locations and perform updates quickly. You can view the tutorial from Google Places to see if this may be a tool perfect for your needs.
