Why a default Facebook Page doesn’t cut it.
Facebook Pages by default will provide the generic features, which all Facebook Pages have, such as, Wall, Info, Photos, Videos, etc., and while these are really important and useful features, they lack the depth required to truly engage your users on the level you would like. Since all these features are available to everyone who signs up for a Facebook Page (which is free), they are not unique and users are no longer interested in interacting with them. For this reason, customization is required.
