Microsites are helpful for consolidating content and keeping relevance all in one spot. One advantage available to microsites is that they inherit statistics such as a high PageRank, TrustRank, and Domain authority from your main site for Search Engine Optimization (SEO). Microsites also benefit from strong internal and cross linking.
Microsites also keep everything together, so that reports (such as Google Analytics) are in one spot and easy to manage. Finally, architecture, navigation, and design scheme are consistent, leading to an aesthetically consistent user experience.

Personas allow greater control over the presentation of content to your users. When you use a persona, you can specify specific criteria using the Rules Engine to designate the most appropriate persona to the user in question. This designated persona will then serve as a guide to the content that displays on the website.
At this time, Personas are only used to deliver different content, and can be used as a Promotion rule. Personas DO NOT map to or feed into the Shipping Engine.
User roles and permissions manage access and capabilities within the Admin Console and the website. Configured Commerce uses role-based security to provide users the permission to access specific areas in the Admin Console and website. Roles are also used to permit users the ability to act on behalf of other users.
