Sites may be able to increase window sizes simply by changing the width of tables or frames . Other sites who have chosen to integrate small browser windows in a boo-like manner probably face an expensive redesign that could have been prevented through a careful usability study. It is often unclear where to click and users visit the same pages several times by mistake. Changing link colors is easy if the site uses stylesheet. A simple search form should be directly available and visible on the homepage .
Many users go directly to the search form when they look for specific information.
Putting the search form on the homepage improves task time for users as search can be seen and used immediately . Text presented with overly small fonts is a hard read making it less likely that users will read and understand product descriptions and other information . Default text size needs to be readable for mainstream users as the act of changing text size is annoying - some users will not even know how to. Pop-up windows disturb users and makes them waste a few valuable seconds wondering what's going on. Pop-ups also destroy the back button thereby making it difficult to return to previous pages.
