• Do not make visited links the same style or color as unvisited ones, as it force the user to memorize where they have been.
• Since it is easier to remember visuals, make page that will be remembered as visually different from the rest.
• Limit groups of similar choices such as links to 5-9 items.
• Aim for memorization of only three items or pages sequentially.
• When response times such as page loads take more than 30 seconds, try to provide your own feedback to the user as a load-time progress bar.

• A Web site A Web site’
• Do not expose physical site file structure, when possible.
• A site A site’
• Aim for a site click depth of three.
• Aim for positive feedback indicating progress towards a destination every click, with a maximum of three clicks without feedback.
• Even for wide site structure, consider a range of 25-81 links per page when page links are ideally clustered.
• The more important the page, the more redundant links should be provided to it.
• Redundant links in a site should be no more than 10-20 percent of a page Redundant links in a site should be no more than 10-20 percent of a page’
• The overriding purpose of any commercial site is to serve the user in a way that hopefully benefits the company either directly or indirectly.
• Entertainment sites may find novelty or surprise more useful than structure or consistency.
• Novice users prefer sites with predictable structure and may put up with extra clicks or a lack of control to achieve a comfortable balance.
• Power users or frequent site user want control and will favor structures that provide more navigation choices.

Navigation Theory and Practice

http://evolt.org/node/60270

• Use simple and memorable URLs to improve navigation.
• http://clickz.com/showPage.html?page=3346531 
• Do not hide URLs Do not hide URLs—complex or simple—
• Use consistent and explicit page labels for all pages in a site.
• Site wide labeling icons or words such as the organization name or logo should always return a user to the home page of the site when clicked.
• Button states should be considered a secondary form of page label and the selected state should always be subdued, not prominent.
• When using color-coding to imply section location, make sure the colors used are significantly different from each other.
• Do not go so overboard with theme-based location hints that you fall into a designer-defined metaphor.
• Do not attempt to mimic the browser history mechanisms with links.
• Avoid links named simple Avoid links named simple “Back.”
• Avoid creating pages that cannot be backed out easily using the browser Back button.
• Users remember their start page as a permanent landmark and the home page of a visited Users remember their start page as a permanent landmark and the home page of a visited 
• Don Don’
• Avoid placing primary navigation on the far right of the screen.
• Home pages or other landmark pages should consider using center Home pages or other landmark pages should consider using center–
• Placement of navigation should be consistent within a page layout.
• Navigation should be consistent and elements should exhibit stability in position, order, and contents.
• When separating navigation choices by position onscreen, understand that four locations is a hard barrier.
• Navigation-oriented pages should fit vertically within the screen whenever possible, as should primary navigation in all other types of pages.
• Minimize the distance between primary site navigation buttons and the Back button.
• Always attempt to limit mouse movement between subsequent navigation items.
• Avoid using frames for layout. Use them for navigation.
• When using frames, make smaller frames control larger adjacent frames.
• Do not turn off frame resizing and scrolling unless resolution is very well accounted for.
• Do not make a remote the mandatory form of navigation.
• Limit scrolling and mouse travel in navigation as much as possible.
• Consider a maximum of three page loads before a result.
  • Linking: Text, Button, Icons, and Graphics
  • http://www.rustybrick.com/seo_articles_3.php
  • http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnacc/html/ATG_TextEquivalentsforImages.asp
• Occasionally provide some unstructured links within document text to promote exploration and thought.
• Always provide textual links at the bottom of pages when using long pages or pages with graphical buttons.
• When using image maps, always provide a secondary navigation from such as text links.
• Never completely remove visited link indication.
• Avoid changing link colors.
• Avoid underlining non-linked text in Web documents Avoid underlining non-linked text in Web documents—
• Avoid automatically turning off link underlining. If you do, add another link indicator form such as Avoid automatically turning off link underlining. If you do, add another link indicator form such as “underline on rollover.
• Avoid using ellipses in links, as they are generally redundant.
• Graphical buttons should have at a minimum an unselected and selected state. Over states and press states should be considered optional.
• Provide good labels indicating the form of the content. Consider using icons to show content types.
• Make sure to indicate if the link will jump them within a page, within a site, or to an external site. Don Make sure to indicate if the link will jump them within a page, within a site, or to an external site. Don’
• Indicate an external link by exposing the URL or using an icon. Indicate file size if triggering a download.
• Use an icon or symbols, or issue an alert dialog before the link.
• Avoid changing visited link colors.
• Add the last modification date to show update times and, where necessary, use a New icon.
• Use an alert, or warn with an obvious label.
• When using status bar messages, consider providing URL information with the text when linking externally.
• Broken links should be considered catastrophic failures.
• Avoid automatic redirects for 404 errors.

Search and Design

http://searchenginewatch.com/showPage.html?page=webmasters

• Utilize past user experience with search engine by using similar layout and labeling in local search facility design, but avoid imitating aspects of public search engines that deal with the uncontrollable nature of public Web sites.
• Do not design pages solely to attract search engines as, ultimately, pages are for people.
• If a site is filled with regular formatted data, very complex to digest data, or contains more than 100 pages, include a local search engine.
• If a site caters to power users or frequent return visitors, provide a search facility.
• When search is available in a site, include a search button or field on all pages.
• A search form as well as the result pages must match the look and feel of a site.
• A search from should match the content being searched.
• Primary search text boxes should be about twice as big as secondary search text boxes.
• It is better to limit search to a topic, category, or idea rather than a section of a site.
• Advanced search facilities must provide instructions and examples.
• Result pages should provide as much information as possible so users can decide what items to peruse further.
• The format of the search results should fit the data that is being returned.

• Allow the user to stretch or shrink screen sizes, be conservative and give yourself a slop factor of as much as 10 percent of the available region.
• When using fixed page sizes, make sure to center your page to reduce the perception of empty space on larger displays.

• Try to fit content vertically within 3-5 screens, if possible.
• Either control page margins or account for their variation with some layout slop factor.
• Provide an obvious link to quickly skip a splash page.

• Clearly indicate Acrobat files with text and an icon, and provide information on using these files.
• Provide an obvious conclusion page for a task.
• Provide a way back to the site from an exit page.
• Let users leave in peace. Avoid Let users leave in peace. Avoid “please don’t go” or “last chance”
• When using text When using text –
• Consider using a text design philosophy on sites where download speed or display flexibility Is paramount.
• Avoid using metaphor design on sites geared toward expert users or heavy repeat use.
• Avoid unconventional or very artistically oriented interfaces designs on task-driven or frequent-use sites.
• Use header-footer design for content-focused sites, particularly when wide content is common.
• Strive always in Web design to be the same, but different. Strive always in Web design to be the same, but different.
