The article I found most informative on breadcrumbs in web usability is from Smashing Magazine. The article is a couple of years old but still very relevant to us today. The article is titled Breadcrumbs in Web Design: Examples and Best Practices by Jacob Gube. The article starts off my explaining exactly what breadcrumbs are to avoid any confusion with trying to use them. Jacob explains that there are three different types of breadcrumbs and when you should use them. Location-based is used to represent the website’s hierarchy, Attribute-based display the attributes of a particular page, and Path-based shows steps the users taken to arrive at a particular page.
Another important section was the benefits of using breadcrumbs:
- Convenient for users
- Reduces clicks or actions to return to higher-level pages
- Doesn’t usually hog screen space
- Doesn’t usually hog screen space
Jacob also states that, like everything in design, there are wrong ways of using breadcrumbs. Some sites have been known
to use breadcrumbs when they don’t actually need to. The breadcrumbs become repeating links of the primary navigation. Another mistake is using breadcrumbs solely as the primary navigation. This can sometimes become very confusing if the navigation is lost somewhere in the body of the website and not in one consistent location. The last mistake is when a website uses breadcrumbs on a page that has multiple categories. This results in difficultly classifying a neat structured category.
The website that I decided to review is ebay.com because of its simple usability. This is a website that use pretty often and noticed after reading chapter 7, that eBay uses almost all of the elements of usability list in the chapter. They have a simple four link primary navigation with drop down menus for each. The design is plain with text only separated by thin vertical lines.
Ebay also uses breadcrumbs pretty loosely. They only appear if you start your search through the site search menus. Design is simply again with a magenta color for visited and a bold black for current page location.
Also text links are everywhere on the home page. There are links such as buyer protection, news, sign in icons, and different advertisements.
Ebay has two different site search drop down menus. This could be a little confusing I suppose however they are very different in style and in content. The left side menu drops out to the right with categories to get you started, and the right side menu is a standard drop down of all the content in alphabetical order.
Submission forms are not exactly used in the standard use of writing a question to the company. However the new register form is probably the closest to this subject of usability.
Ebay also has a simple informative way of let you know when you come to an error from misspelling or something of that nature. If you are close to your possible search it will ask you “did you mean…” However if your search is so far out there than an error message will appear informing you how to search properly.
