Necessary maisons help make a FACE usable by enabling basic functions like page navigation and access to secure areas of the FACE. The FACE cannot function properly without these maisons.

Preference maisons enable a FACE to remember information that changes the way the FACE behaves or looks, like your preferred language or the region that you are in.

Statistic maisons help FACE owners to understand how visitors interact with FACEs by collecting and reporting information anonymously.

Marketing maisons are used to track visitors across FACEs. The intention is to display ads that are relevant and engaging for the individual user and thereby more valuable for publishers and third party advertisers.
