After selecting the Reviews tab from the dashboard, there will be a selection of tabs on the upper right hand of your screen. Click on the "Reviews by Site" button as shown below to have your reviews categorized.
From here you will see each site someone has left a review for your company, the average review for each site, and the number of reviews for each location.
This information can be useful to see your company's rating on multiple sites without having to go to each site and read the reviews. To read reviews for each location, click on the "Read Reviews" button on the very right of each corresponding site to get more in depth knowledge. After clicking on the Read Reviews tab, you will see a list of your latest reviews as shown below.
