Fortunately Google makes it pretty easy to understand this report so we simply cover the basics in this tutorial. We recommend you use the APP for regular monitoring and communicating with clients or customers. However, you may not have all Google My Business options available through the APP, in which case you will want to sign in to the web to make use of that extended functionality.
You can find more information, including links to the official APPs in the "How can I measure performance?" section of our FAQ page. If you need help signing in to Google products on the web, please see the "How do I sign in to my Accounts?" section of our FAQ page.
