Designing Store Navigation and Categories Customers Understand
In this article10 sections
A good ecommerce navigation structure lets a first-time visitor find the right product in a few clicks without thinking about it. It groups products the way customers think about them, uses labels customers recognise, keeps the menu shallow enough to scan, and works as well with a thumb on a phone as with a mouse on a desktop. Navigation also shapes how search engines understand your store, because categories and internal links tell them which pages matter most. Getting it right before a build is far easier than reorganising a live store later.
Key takeaways
- Organise categories around how customers shop, not around suppliers, warehouses or internal departments.
- Use clear, everyday labels that customers would type into a search box.
- Keep the structure shallow: most products should be reachable within three clicks from the home page.
- Design the mobile menu as carefully as the desktop one, because most visitors will use it.
- Test the structure with real people before you build it, and review it as your range changes.
Why navigation decides so much
Most shoppers who do not use search rely on the menu and category pages to find products. If the menu is confusing, they wander, get frustrated and leave. Even shoppers who arrive directly on a product page from a search engine use navigation to explore related items and compare.
Navigation also communicates what you sell. A visitor who opens the menu should understand your range in a few seconds. A clear structure says "we have exactly what you need"; a cluttered one says "good luck finding it".
Finally, navigation affects search visibility. Categories linked from the main menu receive internal links from every page, which signals their importance. A logical hierarchy helps search engines understand how pages relate to each other. Our guide to category page SEO explains how categories win broad searches.
Start with how customers think
The most common mistake is organising the store the way the business is organised: by supplier, brand family, warehouse location or internal department. Customers do not think that way. They think in terms of needs, product types, occasions or rooms.
Ways customers group products
- By product type: sofas, chairs, tables.
- By audience: women, men, children.
- By room or use: kitchen, bathroom, garden.
- By activity: running, hiking, cycling.
- By occasion: gifts, weddings, back to school.
- By brand: important when customers shop by brand, such as electronics or cosmetics.
To find out which grouping your customers prefer, look at how they search, what they ask your team and how competitors in your market organise their stores. Shoppers carry expectations from the big stores they use every day, and matching familiar patterns lowers the effort of finding things.
Most stores combine a main grouping, usually product type or audience, with secondary routes such as brands, occasions or collections. The main grouping should be the one most customers use.
Use the customer's words
Labels should be words customers recognise instantly and would type into a search box. Our guide to ecommerce keyword research shows how to find those words in your search data, customer messages and search engines.
Building your ecommerce navigation structure
- List every product type you sell, using your catalogue data.
- Group them into a small number of top-level categories, typically five to nine for most stores.
- Create subcategories only where a top-level category has enough products and clear subgroups.
- Avoid deep nesting. Each extra level adds a click and a decision.
- Allow products in more than one category where it genuinely helps, such as a table that belongs in both "Dining" and "Garden".
- Avoid near-empty categories, which disappoint shoppers and create thin pages.
Write the tree down as a simple indented list before anyone designs a menu. Read it aloud as if you were a new customer. If a label makes you hesitate, or two categories sound as if they could hold the same product, customers will hesitate too.
Filters often work better than extra subcategories. Rather than creating separate categories for every colour or material, keep one category and let shoppers filter. Our guide to category page UX explains how filters and categories work together.
Designing menus for desktop
Top-level menu
Show top-level categories in a horizontal menu, with clear labels and no more than the screen can fit comfortably. Put the most important categories first, and avoid vague labels such as "Products" or "Shop" that make shoppers open the menu just to find out what is inside.
Mega menus
Larger stores often use mega menus: wide panels showing subcategories in columns, sometimes with images. They work well when they are organised, scannable and quick to open and close. They fail when they become walls of links. Group links under clear headings, limit the number of items and make sure the menu works with a keyboard as well as a mouse.
Search alongside navigation
Many shoppers switch between menus and search. Keep the search box visible next to the menu. Our guide to ecommerce site search covers how to make search work well.
Designing the mobile menu
On phones, the menu usually hides behind a menu icon. That makes it easy to overlook, so the design matters even more.
- Label the icon with the word "Menu" if your audience includes less confident users.
- Show one level at a time, with a clear way back, rather than a long expanding list that pushes everything off screen.
- Use large tap targets with enough space between items.
- Put key shortcuts on the home page, such as the top categories as visual tiles, so many shoppers never need the menu.
- Keep account, help and contact links easy to reach but below the product categories.
Breadcrumbs, footers and other routes
Navigation is more than the main menu:
- Breadcrumbs show where a shopper is and let them move up a level. They also help search engines understand the hierarchy.
- Footer links help shoppers find delivery, returns, contact and policy information, and offer a second route to key categories.
- Related categories on category pages help shoppers move sideways.
- Collections and guides, such as gift ideas or buying guides, offer routes for shoppers who are browsing rather than searching.
Testing your structure before you build
You can test navigation cheaply before any design work begins.
Card sorting
Give a group of customers a list of product types and ask them to sort them into groups that make sense to them, then name the groups. The Nielsen Norman Group explains the method in its guide to card sorting. Patterns in their answers show how customers naturally organise your range and which labels they use.
Tree testing
Show people only the text menu structure, without design, and ask them to find specific products: "Where would you look for a waterproof jacket for a child?" Record where they click first and whether they succeed. Low success on a task shows exactly which part of the structure confuses people.
Analytics after launch
Neither test needs special software to start. A spreadsheet, a handful of customers and an hour of their time will reveal most of the confusing labels and misplaced categories.
Once live, watch which menu items are used, which categories have high exit rates and what people search for when the menu fails them. Site search terms for categories that already exist often signal unclear labels.
Special cases: large, B2B and international stores
Very large catalogues
Stores with tens of thousands of products need a deeper structure, but the same principles apply. Keep top levels broad and familiar, use mega menus with clear groupings, and lean heavily on filters and search rather than ever-deeper subcategories. Popular shortcuts, such as best sellers in each department, help shoppers who are not sure where to start.
Trade and wholesale stores
Business buyers often know exactly what they need and navigate by product family, specification or part number. Offer a quick-order tool and strong code search alongside the category tree, and consider navigation by industry or application if your customers think that way. Our guide to B2B ecommerce portals explains what trade buyers expect.
Several countries and languages
Category names need proper localisation, not literal translation, and the best structure may differ slightly between markets if ranges or shopping habits differ. Keep the underlying structure consistent where possible, so maintenance stays manageable, but let labels and featured categories reflect each market.
Seasonal and promotional navigation
Seasonal sections such as gifts or summer collections help shoppers, but add them alongside the permanent structure, not in place of it. Remove or hide them when the season ends, and keep their URLs for next year if they earned search traffic.
Changing navigation on a live store
Reorganising categories on an established store needs care, because category URLs may have search rankings and links.
- Keep URLs where possible, changing labels and menu positions rather than addresses.
- Redirect any changed URLs permanently to their new equivalents.
- Update internal links so they point to the new structure directly.
- Change in stages for large stores, starting with the areas that confuse customers most.
- Measure before and after: navigation use, category exits, search use and conversion.

Frequently asked questions
How many top-level categories should a store have?
Usually somewhere between five and nine for most stores. Fewer makes groups too broad; more makes the menu hard to scan. Very large stores may need more, organised carefully in a mega menu.
Should I organise by brand or by product type?
By whichever customers use most. In many categories that is product type, with brands as a secondary route or filter. In brand-led markets, such as electronics or beauty, brand navigation can deserve a prominent place.
Can a product appear in several categories?
Yes, when it genuinely belongs in each. Make sure the product has one main URL and canonical tag so search engines see one page, not duplicates.
How often should navigation be reviewed?
At least once a year, and whenever you add a significant new range. Watch analytics and search terms for signs that customers are struggling.
