Abstract:

In several recent websites we have user tested, the site designers have placed important task critical links and information on the right hand side (RHS) of three column page layouts. The user testing was conclusive, users ignore any information presented on the RHS. We think this is a similar effect to the well documented banner blindness. It is essential to ensure that import links or information is not positioned on the RHS as they will surely be ignored.
