Facebook Insights for Pages provides critical data about activity around your Page (such as when someone Likes your Page) and activity around your Page updates (such as when users comment on or Like one of your Page stories).
Facebook Insights is essentially your GPS device to point you towards marketing success on Facebook.
Facebook breaks down its analytics into five reports:
The Overview Report: An overview of how your Page is performing day to day, with sortable post-level details.
The Likes Report: A report about the Facebook users who Like your Page.
The Reach Report: A report about the Facebook users who see your Page content (organic, viral and paid reach), what websites are referring traffic to your Page, and more.
The Talking About This Report: A report about the Facebook users who create content about your Page, and how those stories generate viral reach.
The Check Ins Report: A report about the Facebook users who checkin to your Facebook Place on their mobile device.
Going beyond Facebook Insights
The five reports listed above provide more than enough data to navigate towards most destinations.
However, there are times when you want more insight (pun intended) around your Page and how Facebook users are interacting with your content. This is precisely why Facebook allows you to do a full data dump (up to an 89-day range).
Following are examples of some of the data points unavailable in the Insights reports that you can view by Exporting data:
Page Level Data:
The number of people each day who saw your Page content
The number of people each day who engaged with your Page
The number of people each week who engaged with your Page

The number of people each day who saw your Page or its posts from a story published by a friend.
