Good ecommerce navigation does one job: it helps a shopper answer the question "what kind of product am I looking for?" with as little thinking as possible. Every extra decision you push into the menu is a decision a shopper can get wrong, and a shopper who guesses wrong on a mobile phone usually leaves instead of backing up.
These are the navigation principles our design and development team applies when we plan information architecture for a Shopify or Shopify Plus catalog. They apply whether you sell 40 products or 40,000.
List your main shopping categories in the main navigation
Do not hide the catalog under a single "Shop" item or one very large category. Surface the real shopping categories at the top level.
When you do:
- Users who land deep in the site from search or an ad can immediately understand the range of what you sell.
- Mobile users save clicks, which is where friction compounds fastest.
- Each individual category stays a manageable size instead of becoming an overwhelming wall of links.
Avoid industry jargon and brand-specific language
Use plain, specific words in the navigation rather than internal or industry terms. Many shoppers will not know what a category name means, and brand-invented names are the worst offenders, because only existing customers have learned them.
Plain labels mean the site works for two groups you cannot afford to lose: shoppers who are new to the category, and shoppers who are new to your brand.
Keep any single list to about seven to ten items
Research on working memory puts the practical ceiling at roughly ten items held in the head at once. Keep lists shorter than that so they stay scannable, and remember that shorter is generally better.
This applies to both levels people usually get wrong:
- The main navigation
- Dropdowns and category lists inside it
Make categories clearly distinct, then allow overlap on purpose
A shopper should never have to wonder whether a product lives in one category or another. If the boundary is ambiguous, the menu has moved work onto the customer.
At the same time, mental models differ. If some shoppers would look for a product under category X and others under category Y, put it in both. Multiple pathways to the same product are not redundancy, they are insurance against a lost sale.
Navigation answers "what kind of product," filters answer "which version"
Dividing products too finely makes navigation overwhelming, and it forces a choice inside the menu that belongs on the collection page instead, where the shopper can see actual products and change their mind cheaply.
The split is simple:
- Navigation answers: what kind of product?
- Filters answer: which version?
Prioritize product type in the menu. Save attributes and facets of the same product type, things like size, color, material, and price, for filters.
Give shoppers curated ways to shop, not just product types
Product type is the backbone, but it is not the only way people shop. Curated collections give shoppers who do not yet know what they want a place to start:
- Best Sellers answers the first-time visitor's real question: what is this company known for?
- New Arrivals lets returning customers see what changed, and helps shoppers find the item they saw in an email or an ad.
- Gifts gives gift buyers an entry point when they know nothing about the product category, which matters enormously in the run-up to Q4.
- Sale needs no defense. Everyone looks for it.
Order categories by demand, not by internal logic
In general, your best-selling categories should be listed first, and yes, that includes a best sellers collection. When a list gets long, alphabetical order becomes the more usable choice, because scanning beats guessing. What almost never works is ordering categories by how your team thinks about the catalog internally.
Design within Shopify's practical limits
Shopify menus are flexible, but the structures that stay maintainable and perform well on mobile tend to look the same:
- Roughly 5 to 8 main navigation items
- Up to 3 levels of depth
- Up to 4 or 5 columns within any one dropdown
If your plan needs more than that, the problem is usually the category model, not the menu.
The navigation test
Before you ship a menu, ask these seven questions about it:
- Can a first-time visitor predict what is inside from the label alone?
- Would two different shoppers put the same product in the same category?
- Are categories based on product types rather than attributes?
- Are there fewer than about eight primary navigation choices?
- Does every submenu make scanning easier rather than adding clicks?
- If a product belongs in two places, is it accessible from both?
- Does this minimize clicks for shoppers on their phone?
If a menu fails two or more of these, it is costing you revenue quietly. Navigation problems rarely show up as a single broken thing. They show up as slightly lower conversion on every session, across every channel, forever.
Where this fits in a larger optimization effort
Information architecture is one of the highest-leverage pieces of conversion work because it sits upstream of everything else. A better product page cannot rescue a shopper who never found the category. If you are reworking your catalog structure, it is worth treating it as a merchandising and conversion rate optimization project rather than a design refresh, and validating the new structure against real behavior before and after launch.
Netalico is a Shopify Plus Premier Partner. We plan navigation and category architecture as part of Shopify Plus design and Shopify Plus development work for mid-market and enterprise DTC brands, and as a standalone workstream during replatforming, when the catalog gets rebuilt anyway and the opportunity is at its largest. If you want a read on your current structure, a CRO audit is the fastest way to see where shoppers are getting stuck.
