Overview
Breadcrumbs are a secondary navigation aid that shows the user’s location in the site hierarchy. They enhance usability by providing a quick way for users to navigate back to previous sections or the home page.
Historical Context
The concept of breadcrumbs in navigation is derived from the fairy tale “Hansel and Gretel,” where the children left a trail of breadcrumbs to find their way back home. In web design, the term was first introduced in the 1990s, aligning with the development of more complex websites.
Types of Breadcrumbs
There are primarily three types of breadcrumbs:
- Location-Based Breadcrumbs: Show where the user is in the site’s hierarchy.
- Attribute-Based Breadcrumbs: Display the attributes of the page.
- Path-Based Breadcrumbs: Show the actual path the user has taken to arrive at the current page.
Key Events
- 1995: Introduction of breadcrumbs in early websites.
- 2000s: Widespread adoption as a standard UX pattern.
- 2013: Google introduced breadcrumb support in search results.
Detailed Explanations
Location-Based Breadcrumbs
These indicate the position of a page within the site’s structure, showing the hierarchy from the home page to the current page.
Attribute-Based Breadcrumbs
Typically used in e-commerce sites, these breadcrumbs reflect the attributes or categories a product belongs to (e.g., “Home > Electronics > Mobile Phones”).
Path-Based Breadcrumbs
These are less common and show the exact steps a user has taken to reach the current page. They can be less effective if users arrive at the same page via different routes.
Mathematical Formulas/Models
Breadcrumbs do not involve complex mathematical models, but an algorithmic approach to implementing breadcrumbs could look like:
function generateBreadcrumbs(currentPage) {
breadcrumbs = []
while currentPage has parent {
breadcrumbs.append(currentPage.title)
currentPage = currentPage.parent
}
return breadcrumbs.reverse()
}

- Enhancing SEO by improving internal linking structures.
Applicability
Breadcrumbs are especially useful in:

Considerations

- They should be concise and not cluttered.
- Use separators (e.g., “>”) for clarity.
