Store navigation should help a shopper move from a broad need to a suitable product without having to guess the site's vocabulary. Begin with a small, stable taxonomy, expose the most important paths as real links, and test the same structure with keyboards, touch screens, screen readers, and search crawlers.
Build the structure before the menu
List the products customers can actually buy and group them by the distinctions people use when choosing: product type, use, audience, compatibility, or another durable attribute. Keep promotional collections separate from the core taxonomy because campaigns expire. A menu should represent the site's information structure, not every filter in the catalog.
Give each label a clear destination. Avoid several labels that lead to nearly identical lists, and avoid internal jargon that is not explained on the page. Put high-value categories close to the home page, then link from category pages to subcategories and products. Google's ecommerce site-structure guidance recommends that products be reachable through navigation links and notes that Googlebot generally does not submit searches into a site's search box to discover products.
Use links and meaningful menu structure
Use ordinary anchor links with valid destinations for pages a shopper or crawler should reach. Google specifically recommends `a` elements with `href` attributes rather than JavaScript events on unrelated elements for navigation. Search, filters, and recommendation widgets can supplement the hierarchy, but they should not be the only path to important products.
The W3C Web Accessibility Initiative's Menus Tutorial recommends structure and labels that reflect the menu hierarchy, recognizable visual states, and fly-out behavior that works for mouse and keyboard users. Mark the current location, provide visible focus, and make touch targets usable. A navigation link does not need application-style menu roles merely because it appears in a header.
Keep mobile and desktop paths consistent
A smaller screen can collapse the presentation, but it should not hide essential destinations or change category names without a reason. Make opening and closing controls operable by keyboard, preserve focus, announce expanded state when appropriate, and prevent the menu from trapping a user. Avoid hover-only submenus and controls that disappear before a pointer can reach them.
Add breadcrumbs when they help explain location, especially for deep category paths. Treat them as a secondary route, not a replacement for the main menu. Provide search for a large catalog, but monitor zero-result queries and repeated reformulations because they can reveal missing labels or synonyms.
Test finding tasks and crawl paths
Create representative tasks such as finding a compatible accessory, comparing two categories, returning to a parent category, and locating policies. Test with real devices and without a mouse. Confirm that focus order follows the visual order, the current page is identifiable, escape and back behavior are predictable, and every control has a useful name.
Crawl the deployed site and confirm that all canonical category and product pages are reachable through links, return successful responses, and are not duplicated by uncontrolled filter URLs. Review internal-link depth and orphan pages after catalog changes. A practical store navigation system has named owners, a documented taxonomy, accessibility checks, and a change process that removes stale links when products and promotions change.
