Value For Effort
Value for Effort (VFE) is the principle that an action must have sufficient benefit for low enough opportunity cost.
This guiding principle allows effective implementation of lower cost solutions for acceptable increases in sales or acquisitions, where a number of potential solutions are
possible, but a good VFE solution is the most appropriate for a given budget.
Video On Demand
VOD (Video on demand) - an online service providing TV or movies via a broadband connection. As the name suggests, the services are available at the time of request,
rather than on a programming schedule that would have on traditional television.
Virtual domain
A domain that is hosted on a virtual server. The domain is unique, but the IP address is normally shared with other domains. This has some implications for SEO.
Virtual server
When a domain is hosted on a virtual server, it means that it shares that server with other domains. This is a very cost effective way of hosting web sites,
but access speeds are not as high as for domains hosted on dedicated servers.
Visitor
The term is sometimes confused with unique visitor. The difference is that one unique visitor visiting a site repeatedly over a period of time will show up
on the site's log file as many visitors. The term therefore refers to the number of times people visit a site - not the actual number of people visiting a site.
Vortal
The term is used to describe portals that focus on one specific (vertical) topic. In other words, they target at a specific group of people -
like programmers, SEO specialists etc. - by providing in-depth information on that topic.
