What is a usable market?

A usable market is: a market where you exert the least effort for the greatest understanding possible, that allows you to comfortably engage at the level (and in the role) you wish, results in your maximum possible satisfaction, and where your actions in the market feed back positively into the market.

The Formula for Internet Site Success

Jakob Nielsen:

The formula for website success is:

  • B = V ? C ? L


  • B = amount of business done by the site-
  • V = unique visitors coming to the site-
  • C = conversion rate (the percentage of visitors who become customers)- (Note that the concept of conversion applies not only to e-commerce sites, but to any site where there is something you want users to do.)
  • L = loyalty rate (the degree to which customers return to conduct repeat business).
