Facebook Insights aggregates information on the sharing and engagement of website links spread throughout Facebook. Website owners can see information for URLs from their domains through the Insights Dashboard. Website owners that implement Social Plugins can also information on the number of "Likes" made on their site content. Website data is aggregated and reported on Insights on a domain and URL level.

To see Insights for your website, you must first claim your domain by associating it with a Facebook page or application that you manage, or with your Facebook account. To do this, click on the green "Insights for your Domain" link from the Insights Dashboard. The window that appears will provide a meta tag that must be added to the root of your web page. Once that is done, type in your domain address into the text box and select the account to link it with. Once checked, your claimed domain will appear on the left side navigation bar under the "domains" section.

You can associate your website with either your Facebook account or to a Page or application you manage. When you associate the website with either a Page or application, all users that either administer that Page or own that application will have access to Insights for your website.

Facebook Insights allows users to see aggregated data at a domain level. Domains can either be top-level domains such as www.domain.com or include second level domains such as sub.domain.com. If you own multiple subdomains in this fashion, it is recommended that you claim each subdomain through the Insights claiming process as if they were distinct properties.

It is important to note that Insights aggregates data across URLs based on distinct domains such that data for URLs within www.domain.com will not appear for the owner of sub.domain.com.

The Insights Dashboard displays the most shared URLs for your domain. Clicking on table row will open Insights for that URL. You can also type the URL directly into the search box below the domain name to see Insights for a specific URL.
