Facebook Insights provides Facebook Platform developers and Facebook Page owners with metrics around their content. By understanding and analyzing trends within user growth and demographics, consumption of content, and creation of content, Page owners and Platform developers are better equipped to improve their business and create better experiences on Facebook.
To see metrics on your Facebook Page or Platform app, go to the Insights Dashboard. Only Page administrators, app owners, and domain administrators can view Insights data for the properties they own or administer. To view comprehensive Insights on your specific Page, Platform app or website, click on the corresponding item on the left navigation bar. Developers that need to access this data programmatically can access Insights through the Graph API Insights object and Insights FQL table.
Facebook Insights for Domains offers a consolidated view of key metrics for any website, even those that have not implemented Facebook Platform. For example, if a user links to your site in their Facebook status message, that data is included in the analytics for your domain. You can access sharing metrics and demographic information per domain and per URL so you can optimize your content for sharing and better tailor your content to your audience.
Claiming a Domain
To see Insights for your website, you must first claim your domain by associating it with a Facebook App that you manage, or with your Facebook user account. To do this

The following are the meta tags to add to your website and correspond with the access privileges granted to an individual user or admins for an app:
<meta property="fb:admins" content="user_id" />
<meta property="fb:app_id" content="your_app_id" />
Use Insights for your app to track how users are interacting with your app to build the best possible experience for your users. For app administrators, Insights includes feedback for stream stories, referral traffic to your app, a breakdown of what user actions contribute to active user count, demographics on authorized users and active users, and the number of times permissions are prompted and granted.
Detailed Insights on Open Graph activity for your app is also available.
In addition, it provides diagnostics for your app so that you can track API errors as well as get access to allocations and throttling information.
You can access Insights for your app directly through the Insights Dashboard or by selecting your app in the developer app and clicking the “insights" link
If you administer a Facebook Page or have integrated the Open Graph protocol into your Web pages, you can see analytics for referral traffic and stream stories in the Insights dashboard, as well as tab views for your Facebook Pages. Insights will capture engagement with Pages regardless of whether an action was taken on or off Facebook.
Dashboard Export
The Insights Dashboard allows you to export all data for your app, page or domain into a .CSV or Excel file. To do this click on the button 'Export' on the top left corner of your Insights Dashboard for any app, page or domain. The export dialog also allows you to specify a date range for which you wish to see the data.
API
Beyond the Insights Dashboard, developers can use the Graph API or FQL tables to access additional data about their Page, app, or domain. To help you get started, you can use the Graph API Explorer to play around with different Graph API and FQL queries.
How long does it take Facebook to process and display Insights data?
The data that you access through Insights is at most 48 hours old. In the event of a delay, we will announce it on Platform Live Status.
What time zone are your metrics based on?
All daily, weekly and monthly Insights data are aggregated according to PDT (Pacific Daylight Time).
Is there a minimum number of users to see Insights for Pages?
Yes. For user privacy reasons, Insights are only provided to Pages with greater than 30 users who like that Page.
What is an "active user"?
For apps, people are considered active users if, having granted the app permissions, they visited the app Canvas Page; viewed the app on a Page profile tab; visited an external website when logged into that site with their Facebook account; or had the Facebook API called on their behalf with an active user session. Visits to your app by users who have not granted permissions to your app are not considered 'active users' but are counted in other metrics such as impression data. For Pages, people are considered active users if they have visited the Page; viewed a post by the Page; or interacted with a post.
What geographic and demographic data is available?
Facebook Insights provides the ability to see geographic and demographic data for people that have Liked a Page or installed an app. Location data is based on the geographic location of each person as determined by their browser IP address and is limited to the top 20 countries and cities. All other demographic information is aggregated and non-personally identifiable.
I am a Page administrator. Why am I not able to see Insights for my Page?
Insights are only available to pages which are liked by at least 30 people. Insights will start showing up for your page once your page has 30 users who like it.
Why does the count next to my Like Button not match what I see in Insights?
The count next to the Like Button represents the sum of Like Button clicks, News Feed likes, News Feed comments, and shares on Facebook.
