Error Description Avoid opening a new browser window when a user clicks on a link unless it is clearly marked that a new window will be opened; users may not see that a new window has been opened, which will complicate navigation, especially moving backward. Make sure users can use the back button to return to prior pages. Avoid opening new browser windows, using an immediate redirect where, when users click the back button, they are pushed forward to an undesired location, or prevent caching such that each click of the back button requires a new trip to the server. Avoid overly long and complex URLS because it makes it more difficult for users to understand where they are and can cause problems if users want to email page locations to colleagues. Avoid having pages with no "parent" that can be reached by using a back button; requires users to "hack" the end of the URL to get back to some other prior page. Avoid placing navigational links below where a page opens because many users may miss these important options that are below the opening window. Make sure your pages conform to users' expectations by providing commonly used icon links such as a site logo at the top or other major elements. Also place these elements on pages in a Opening New Browser Window Breaking or Slowing Down the Back Button Complex URLS Orphan Pages Scrolling Navigation Pages Lack of Navigation Support consistent manner. Make sure you leave a border around images that are links, don't change link colors from normal defaults, and avoid embedding links within long blocks of text. Avoid not turning off link-marking borders so that links clearly show which links users have clicked and which they have not. Make sure users know which links are internal anchor points versus external links, and indicate if a link brings up a separate browser window from those that do not. Finally, make sure link images and text provide enough information to users so that they understand the meaning of the link. Avoid using image buttons that don't clearly change when being clicked; use web GUI toolkit buttons, HTML form-submit buttons, or simple textual links.
