Usability
Usability: This term refers to how "user friendly" a web site and its functions are. A site with good usability is a site that makes it easy for visitors to find the information they are looking for or to perform the action they desire. Bad usability is anything that causes confusion or problems for the user. For example, large Flash animations served to a visitor with a dial up connection causes poor usability. Easy, intuitive navigation and clear, informative text enhance usability.
Viral Marketing
Viral Marketing: Also called viral advertising, viral marketing refers to marketing techniques that use pre-existing social networks to produce increases in brand awareness. The awareness increases are the result of self-replicating viral processes, analogous to the spread of pathological and computer viruses. It can often be word-of-mouth delivered and enhanced online; it can also harness the network effect of the internet and can be very useful in reaching a large number of people rapidly.
