I am working on a website that offers a service to customers. As part of this, there is obviously lots of informational, marketing and news information, as well as a regular "backend" where actual customers signup, login and then make use of the service.
The informational site requires fairly frequent updates from marketing. Marketing is constantly concerned with SEO, news updates, PR etc.
The main backend site still requires a lot of development, but this is a "registered" user only area. It doesn't need SEO and such frequent updates.
The two seem fairly distinct to me. For this reason, I am thinking of splitting out the informational website into www.example.com and the regular backend into user.example.com or another similar subdomain.
Are there any problems with this approach?
