The SEO tab allows you to define your own META tags which appear in the portal. They are used to tell search engines some basic information about your content, such as the record title, keywords, and a description. It's also useful if you wish to plug-in Social sharing of your records using the Open Graph protocol.
For Example: Open graph meta tags allow you to control what content shows up when a page is shared on a social network.
By default only one entry will exist, this will be to set the page title for each record.
