Portals vs. Websites
Portals may look like a website, but have advanced capabilities to manage members, analyze their activity as they engage with content, offer discussion forums, offer a personalized content experience and use notifications and emails to stimulate engagement. When portals are networked together, they offer the efficiencies of adding content and marketing assets in a centralized location and selectively delivering it to other portals in the network.
Websites provide information in an online location but lack the capabilities and functionality offered by portals. Website content is available to all viewers but fails to provide a customized view of that content. Website viewers tend to look at information but do not interact with the website the way they do with a portal experience.
