On websites that have a lot of pages, breadcrumb navigation can greatly enhance the way users find their way around. In terms of usability, breadcrumbs reduce the number of actions a website visitor needs to take in order to get to a higher-level page, and they improve the findability1 of website sections and pages. They are also an effective visual aid that indicates the location of the user within the website’s hierarchy, making it a great source of contextual information for landing pages.
What is a breadcrumb?
A “breadcrumb” (or “breadcrumb trail”) is a type of secondary navigation scheme that reveals the user’s location in a website or Web application. The term comes from the Hansel and Gretel2 fairy tale in which the two title children drop breadcrumbs to form a trail back to their home. Just like in the tale, breadcrumbs in real-world applications offer users a way to trace the path back to their original landing point.
You can usually find breadcrumbs in websites that have a large amount of content organized in a hierarchical manner. You also see them in Web applications that have more than one step, where they function similar to a progress bar. In their simplest form, breadcrumbs are horizontally arranged text links separated by the “greater than” symbol (>); the symbol indicates the level of that page relative to the page links beside it.
In this article, we’ll explore the use of breadcrumbs on websites and discuss some best practices for applying breadcrumb trails to your own website.
When Should You Use Breadcrumbs?
Use breadcrumb navigation for large websites and websites that have hierarchically arranged pages. An excellent scenario is e-commerce websites, in which a large variety of products is grouped into logical categories.
You shouldn’t use breadcrumbs for single-level websites that have no logical hierarchy or grouping. A great way to determine if a website would benefit from breadcrumb navigation is to construct a site map5 or a diagram representing the website’s navigation architecture, and then analyze whether breadcrumbs would improve the user’s ability to navigate within and between categories.
Breadcrumb navigation should be regarded as an extra feature and shouldn’t replace effective primary navigation menus. It’s a convenience feature; a secondary navigation scheme that allows users to establish where they are; and an alternative way to navigate around your website.
Types of Breadcrumbs
Location-based breadcrumbs show the user where they are in the website’s hierarchy. They are typically used for navigation schemes that have multiple levels (usually more than two levels). In the example below (from SitePoint7), each text link is for a page that is one level higher than the one on its right.
Attribute-based breadcrumb trails display the attributes of a particular page. For example, in Newegg8, breadcrumb trails show the attributes of the items displayed on a particular page:
This page displays all computer cases that have the attributes of being manufactured by Lian Li and having a MicroATX Mini Tower form factor.
Path-based breadcrumb trails show users the steps they’ve taken to arrive at a particular page. Path-based breadcrumbs are dynamic in that they display the pages the user has visited before arriving on the current page.
Benefits of Using Breadcrumbs
Here are just some of the benefits of using a breadcrumb trail.
Convenient for users
Breadcrumbs are used primarily to give users a secondary means of navigating a website. By offering a breadcrumb trail for all pages on a large multi-level website, users can navigate to higher-level categories more easily.
Reduces clicks or actions to return to higher-level pages
Instead of using the browser’s “Back” button or the website’s primary navigation to return to a higher-level page, users can now use the breadcrumbs with a fewer number of clicks.
Doesn’t usually hog screen space
Because they’re typically horizontally oriented and plainly styled, breadcrumb trails don’t take up a lot of space on the page. The benefit is that they have little to no negative impact in terms of content overload, and they outweigh any negatives if used properly.
Reduces bounce rates
Breadcrumb trails can be a great way to entice first-time visitors to peruse a website after having viewed the landing page. For example, say a user arrives on a page through a Google search, seeing a breadcrumb trail may tempt that user to click to higher-level pages to view related topics of interests. This, in turn, reduces the overall website bounce rate9.
Mistakes in Breadcrumb Trail Implementation
Using breadcrumb trails is a fairly straightforward affair, and there are only a few guidelines to consider before deciding to implement them on a website. Let’s take a look at some common mistakes to avoid.
Using breadcrumbs when you don’t need to
A common mistake in implementing breadcrumbs is using them when there is no benefit.
In the above example, Slicethepie10 risks overwhelming users with too many navigation options. The (1) primary navigation, (2) breadcrumb trail and (3) secondary navigation are very close together. The breadcrumb trail in this application offers users no added convenience because the secondary navigation for lower-level pages sits right below it. Additionally, clicking on the second-level link in the breadcrumb trail (“Music”) takes you back to the first tab (“Listen”), which mistakenly suggests that the first tab is on a higher level than the other two (“Search” and “Artist hall of fame”).
Using breadcrumb trails as primary navigation
As stated earlier, use breadcrumbs as an optional aid to navigation.
In the above example, mefeedia11 does not offer a primary navigation menu for viewing videos. Though there is text link navigation in the footer section, there’s no navigation menu in the body of the pages, making it hard to navigate to other sections of the website.
If you arrive on a video page directly — say, for example, through a Google search result — the only navigation option you may have is the breadcrumb trail. Or if you’ve already been browsing a website’s pages and reach a page that does not display the primary navigation menu, you will have to hit the “Back” button in your browser to access the main menu.
Using breadcrumbs when pages have multiple categories
Breadcrumb trails have a linear structure, so using them will be difficult if your pages can’t be classified into neat categories. Deciding whether to use breadcrumbs largely depends on how you’ve designed your website hierarchy. When a lower-level page is (or can be put) in more than one parent category, breadcrumb trails are ineffective, inaccurate and confusing to the user.
Breadcrumb Navigation Design Considerations
When designing a breadcrumb navigation scheme, keep several things in mind. Let’s take a look at some questions that might arise when you’re working with breadcrumbs.
What should be used to separate link items?
The commonly accepted and most recognizable symbol for separating hyperlinks in breadcrumb trails is the “greater than” symbol (>). Typically, the > sign is used to denote hierarchy, as in the format of Parent category > Child category.
Other symbols used are arrows pointing to the right, right angle quotation marks (») and slashes (/).
The choice depends on the aesthetics of the website and the type of breadcrumb used. For example, for path-based breadcrumbs in which the links do not necessarily have a hierarchical relationship to each other, using a “greater than” symbol may not convey their relationship accurately.
How big should it be?
You don’t want your breadcrumbs to dominate the page. A breadcrumb trail functions merely as an aid to users (a convenience); its size should convey this to users and thus should at least be smaller, or less prominent, than the primary navigation menu.
A good rule of thumb to follow when sizing your breadcrumb trail is that it shouldn’t be the first item that grabs the user’s attention when arriving on a page.
Where should breadcrumbs be located?
Breadcrumb trails are usually displayed in the top half of the page, below the primary navigation menu if a horizontal menu layout is used.
Now that we’ve discussed the who, what, when, where, why and hows of breadcrumb trails, we should take a look at some live examples. In the following section, you’ll find a few examples of great websites that use breadcrumb trails.
1. Classic Text-Based Breadcrumbs
2. Replacing “>” with Other Symbols
3. Beyond Simple Text Links
One current trend in breadcrumb design basically says, “Breadcrumbs don’t have to be simple”. In these designs, you’ll see beautifully styled breadcrumbs that integrate well with the overall design.
4. Breadcrumbs for Multi-Step Processes
5. Breadcrumbs with Sub-Navigation
Here are some examples of breadcrumb trails whose links, when clicked on or hovered over, open a sub-navigation panel that lists additional attributes or locations.
Clicking on a breadcrumb link takes you to that item’s page, while clicking on the downward-pointing arrow opens additional options.
