Stability of interfaces for seniors: Elder users generally have slower reactions, and also they shall not be distracted without a reason. The designers should limit the usage of automatic system action on a website, such as auto-changing some fields in an input form, or automatically taking user to a new location (page) on a website. The usage of distracting elements, such as animated .gif pictures or aggressive Flash animation should be also limited if possible. This strategy is somehow contrary from design recommendations for regular users, who indeed may benefit from automation of some tasks and re-directing at web pages.

Contrast of hyperlinks for seniors: Use large text that contrasts well with the background for navigational elements. Consider a link’s color contrast both before and after it is visited.

Dynamical interface elements for seniors: Pull-down menus, hierarchically walking menus, and other moving interface elements cause problems for seniors who are not always steady with the mouse. Better to use static user interface widgets and designs that do not require pixel-perfect pointing.

Colorize hyperlinks for seniors: When websites violate the guideline to use different colors to clearly distinguish between visited and unvisited links, seniors easily lose track of where they have been. We’ve certainly seen the same problem among all age groups: It's confusing when websites change the standard link colors, and it's particularly confusing when the same color is used for all links, whether or not you have visited the destination page. However, seniors have a harder time remembering which parts of a website they have visited before, so they are more likely to waste time repeatedly returning to the same place.
