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 theInsights 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.
