Since the introduction of External Sharing feature and Simple Public facing site in SharePoint Online, many of my partners and customers are asking questions on report that give details on no. of times a site is accessed, no. of unique users/visitors...basically features related to Web Analytics.
Well we can get this kind of reporting out of the box in SharePoint Online itself. Follow the below simple steps to know more.
Step1 : Open any of your Private Site Collection or Public site in SharePoint Online. ( Yes, we have this reporting even for simple public website in SPO :) )
Step2: Your Private Site Collection URL will be https://something.sharepoint.com/Pages/default.aspx or https://something.sharepoint.com/sites/anything/pages/default.aspx or https://something.sharepoint.com/teams/anything/pages/default.aspx
Step3 : Now as you know the URL, create a Hyper Link on your Private SharePoint Site and get access to the report anytime :)
