Each Reputation Manager report is specific to a single location, and each Reputation Manager credit is only useable for one location. We use your address / location details to identify your listings on the review sites that we track.
So, for multi-location businesses, you will need to create one Reputation Manager report per location. Our handy Reputation Manager Enhanced Overview provides more information here.
If you have over 100 locations, please get in touch with our Enterprise team who will be able to help.
