Usage of a German prevention and health promotion web portal and cost per pageview: A life-cycle assessment.

Usage of the web portal showed temporal variation and peaked before the middle of its 6.5 year life-cycle. Development and need for updates may require substantial investment in a web portal, such that a pageview can come at a considerable expense, even in small-scale projects. Assessing and discussing the cost-effectiveness of a web portal is therefore desirable.
