How to Optimise Website Navigation for eCommerce

Optimising navigation is often one of the biggest CRO wins for ecommerce websites, precisely because it so often gets overlooked or forgotten about.

Navigation decides how quickly a shopper landing on your site can move from "I’m interested" to "this looks like the right product." If the menu uses internal language, hides high-intent routes, or makes mobile users tap through too many layers before they see a useful route, your product pages have to rescue a journey that started badly.

At Blend, we see this in Shopify CRO audits all the time. A store may have good products, good traffic and decent PDPs, but visitors aren't reaching the right products easily enough. Before you rewrite the product page or change the cart, check whether the shopper can find the thing they came for.

Here's how to optimise website navigation for an ecommerce website, with examples from real, successful sites.

Start With the Job Your Menu Has to Do

When you come to designing the information architecture of your menu, you might ask yourself "Which pages should we include?" Thing is, that's not a well-defined question. Start with the problem you're really trying to solve instead, and ask "What are shoppers trying to do when they open the menu?"

Using this Jobs to Be Done (JTBD) approach, you immediately go from a blank slate to seeing that a first-time coffee buyer may be trying to find a flavour they will like. A runner may be trying to find a shoe for stability or trail use. A parent may be trying to find a gift that arrives before the weekend. Those are different journeys, and they do not always map neatly to how the business names its collections.

A useful example from our own A/B test library is Stone Creek Coffee. We tested a navigation structure built around flavour profiles, such as Bright, Balanced and Bold. We wanted to use the shopper's language and mentality rather than relying only on standard category logic. The flavour-led variant increased revenue per visitor by 11%, conversion rate by 2%, and average order value by 9%. You can read the test here: Testing a New Navigation Structure for CRO Gains.

For that shopper, flavour was a faster route into the range than asking them to understand coffee taxonomy before they had chosen a product. That is the sort of detail you only get by thinking about the customer’s decision, not the store’s filing system.

Choose the Right Structure: Tiered Menus and Mega Menus

A tiered menu sends the shopper through layers. They choose a top-level category, then a subcategory, and sometimes a third level after that.

A mega menu opens a wider panel where you can show several category groups at once, often with images, featured links or promotional routes.

Both can work. The right choice depends on how complicated the catalogue is and how much context the shopper needs before choosing a route.

A tiered menu suits a store where the categories are familiar and the shopper knows where they are heading. This is usually applicable for fashion, when the route is obvious: Men > Shoes > Trainers. The customer is not learning the category and they don't really need any new information about it. Instead they just need to be able to narrow it.

A mega menu is more useful when the shopper needs to compare routes before they commit. That might mean a wide homeware range, a multi-sport catalogue, or a store where shoppers browse by need as much as by product type.

UK fashion-giant-cum-department-store Next is a useful reference point. The desktop navigation gives shoppers recognisable department-level routes: women, men, boys, girls, home, baby, beauty, furniture, brands, sports and clearance - the first level is instantly recognisable and universally understandable.

SportsShoes.com is more specialist. Its navigation surfaces routes like Carbon, Cushioned, Stability, Trail, Waterproof, Run, Hike and HYROX. That works because runners and outdoor shoppers often browse by use case or performance need, not only by brand.

If you use a mega menu, keep it under control. You don't want a glorified sitemap - usability is everything. Put the routes with the highest buying intent near the top, keep headings plain, and use imagery when it helps someone recognise a category faster.

We increased revenue per visitor by 42% for one client with an A/B test using supporting imagery in the mobile navigation.

Also check how the menu behaves over your homepage. We've seen plenty of flyout menus cover hero copy, sale messaging or product tiles in a way that looks accidental. If the menu opens over page content, it needs to look intentional, with enough contrast, spacing and close behaviour for the shopper to understand what just happened.

Design Mobile Navigation as Its Own Experience

Most ecommerce traffic is mobile-heavy, so mobile navigation cannot be an afterthought. A desktop menu squeezed into a hamburger drawer usually asks too much of the shopper.

Mobile users have less screen space, less tolerance for fiddly interactions and less patience for long category lists. They also tend to rely more heavily on search when they already know what they want.

We have tested mobile navigation changes directly. In another Blend mobile category navigation test, adding clearer visual support to the menu increased conversion rate by 18%, revenue per visitor by 28%, and average order value by 8%. The previous menu asked shoppers to understand category differences from text alone. The variant made recognition faster.

You don't need images in every mobile menu. A store selling familiar clothing categories may not gain much from thumbnail images alongside "T-Shirts" or "Jeans". A store selling unfamiliar, technical or visually distinctive products may benefit far more.

On mobile, check the basics with your phone in your hand. Are the tap targets comfortable? Does the back control move up one level or close the whole menu? Can you close the menu without hunting for a tiny X? Does the menu remember where you were, or throw you back to the top every time?

Small annoyances stack quickly on mobile.

SportsShoes is a good example again because its mobile menu includes utility routes such as Order Tracking, Delivery & Returns, FAQs, WhatsApp and Contact Us. People open menus for help as well as shopping. The trick is to include support routes without pushing product discovery too far down the menu.

Make Hover Menus Behave Like Real Hands Use Them

Desktop navigation still matters, especially for considered purchases and B2B-ish browsing behaviour. One of the most common problems is a flyout menu that disappears when the cursor moves from the parent item to the submenu.

You can catch this in 10 seconds. Open the menu, move your cursor diagonally towards a subcategory, and see whether the panel vanishes. If it does, add a short delay or hover-intent logic. This common pitfall is massively frustrating for users - they shouldn't feel like they're doing keyhole surgery just to navigate the site.

Also check whether the hover area is wide enough. Some menus leave a dead zone between the top-level link and the open panel. The shopper thinks the site is glitching, opens the menu again, tries more slowly, then (best case) defaults to search or (worst case and often more likely) gives up and bounces.

This is one of those CRO fixes that looks boring in a backlog but saves a surprising amount of frustration.

Use Plain Category Labels

Write your menu labels for the shopper, not for the team that created the product range.

Words like 'Essentials,' 'Systems,' 'Solutions,' 'Signature,' 'Core' and 'Collections' might make sense to you, but to a new visitor, they can feel vague. If a shopper has to click to understand what a label means, the label isn't really doing its job.

This is where user testing helps. Give someone a task and watch what they do. For example, ask them to find a first-time coffee subscription, a waterproof running shoe, a replacement part, or a gift under £50. If they hesitate over the same labels, the menu is telling you where the language is weak.

Treat Site Search as a Main Navigation Route

Site search is often treated as a small utility in the header. This is a big CRO mistake; for high-intent shoppers, it can be the quickest route to purchase.

Someone who searches for a product name, ingredient, size, part number, colour or use case is telling you what they want. If the search bar is hidden on mobile, the placeholder copy is vague, or obvious terms return poor results, you are adding friction to one of the warmest behaviours on the site.

In one Blend test, exposing the search bar on mobile lifted conversion rate by 3.34% and revenue per visitor by 9.93%. You can read the test here: Exposing the Search Bar on Mobile Devices - one of our greatest hits and a recommendation we nearly always make where it's not already implemented.

Don't underestimate your search bar placeholder copy either. Usually treated as a throwaway, it's an opportunity to drive action, improve customer experience and also inject some brand personality. With an automotive client we saw uplifts by changing the copy from a generic placeholder to "Rev up your cart".

Updating the search bar copy for our client Azuna increased revenue per visitor by 3%, subscription revenue per visitor by 4.53%, and subscription orders per visitor by 2.26%. Full write-up here: Improve Mobile Search Engagement with Clearer Copy.

Review your site search data at least monthly. Look for obvious product terms returning no results, common misspellings, searches where users leave immediately, and phrases that shoppers use instead of your product names.

Those terms are useful beyond search too. If lots of shoppers search for "waterproof trail shoes," that phrase may deserve its own visible category route. If they search for "refills" but your menu says “Consumables,” the customer has already given you the better label.

Remember that Navigation Exists Beyond the Header

The header gets the attention, but shoppers navigate through the whole site.

Product cards help people navigate when they explain enough to support comparison. Filters help people navigate when they match the way shoppers narrow choices. Breadcrumbs help people recover when they land in the wrong place. Footer links help people find support, returns and delivery information when the page hasn't answered a final doubt.

Even blog content can act as navigation. A buying guide that links to a relevant collection, a comparison article that links to two PDPs, or a care guide that links to refills can move a reader into the buying journey without relying on the main menu.

If you're reviewing ecommerce website navigation, include:

• Header menu
• Mobile drawer
• Site search
• Collection filters
• Product cards
• Breadcrumbs
• Footer links
• Blog-to-product links
• PDP recommendation modules
• Cart cross-sells

Our guide to Shopify theme optimisation for CRO explains how hierarchy, navigation and page structure work together.

Test Bigger Navigation Changes Before You Roll Them Out

Some navigation fixes don't need an A/B test. Broken links, misleading labels, poor tap targets, missing close buttons and no-result searches for products you sell are just straightforward fixes.

Larger navigation changes carry more risk. If you restructure the primary menu, add mobile imagery, expose search, change category logic, or change routes into subscription products, you could affect product discovery and your core CRO metrics of conversion rate, AOV and revenue per visitor at the same time.

At Blend Commerce we usually treat navigation work as part of the CRO decision process. First, diagnose where discovery is failing. Then decide whether the change should be implemented, researched, tested or deleted from the roadmap. (Our article on when to A/B test vs implement CRO changes explains how we make that call.)

If you need help finding the product discovery issues on your store, start with our CRO audit service. If you already know the issue and need the work designed, built, QA’d and measured, see our Shopify CRO services.

A Practical Website Navigation Checklist

Use this before you redesign your menu or brief a developer.

1. Write down the main jobs shoppers are trying to complete when they open the menu
2. Check whether your top-level labels use shopper language
3. Compare desktop and mobile separately. Do not assume the same structure works for both
4. Put high-intent mobile routes near the top
5. Make search visible enough for people who already know what they want
6. Review no-result searches and add synonyms where needed
7. Test flyout menus with natural cursor movement
8. Check mobile back, close and scroll behaviour
9. Make delivery, returns and support easy to find without crowding product routes
10. Use analytics and user testing to see whether navigation changes improve product discovery, not only menu clicks

Navigation looks small until it fails. Then the damage shows up everywhere else: fewer product views, lower add-to-cart rates, frustrated mobile sessions and search data full of terms the site should already understand.

Start with the shopper’s task. Make products easy to find and your signposting obvious. Then keep a close eye on whether more people reach the right product. Simple, right?
