Moz Local helps you manage your online listing with one click. It is a great website for any size business. Check on line listing with different directories and verify information inconsistencies.  Save time by having Moz local list your business correct the first time.  Personally this has been a great tool. Setting up multiple businesses and getting them listed on different online directories can be a pain. This platform allows you to not only check what directories you are already set up with but it also helps you list a business with all directories at once. Inconsistent information can confusion search engines and it is important to have your business listed correctly and consistent.  https://moz.com/local/overview
