These guidelines are basically for those sites who wants to deliver a "usable" interface, unlike graphics & animation rich websites who are visually appealing but sometimes lacks ease of use, due to unclear navigation systems.
Following are the few points which serve as a generic guideline while designing a navigation.
- Navigation Placement: Make sure that the navigation is placed at an easily visible location, so that the users don’t have to“guess” or “search” for it.
- Place important things on high: Keep the important things on the top area of the page, preferably in the first half of the page. Such significant information should get displayed first to the user.
- Banner Blindness: Make sure that you don’t put any content above the ad. Banners as users are tend to ignore all the content that’s displayed above ad banners. Make sure especially that navigation is not placed above such banners, as ‘navigation’ is very important & should not be ‘lost’.
- Avoid being unconventional: Designing website navigation in an ‘unconventional’ way to make the site stand out from the crowd is NOT a good method of navigation design. It becomes difficult for the users who are now quite used to the general web design practices of designs, navigations & such other generic functionalities.
- Home link should always be there: Homepage being core of any website, a back-link to the homepage should always be there. Also, it is very much possible that user might have landed up on your website through some search engine or have come directly to your sub-page / inner page, a “home“ link always helps them to come back to the homepage of your website.
