After running a store long enough, I’ve realized most shoppers leave not because the products are bad, but because they can’t find what they want fast enough. Most of that friction lives in the navigation. This article gathers the five most common Shopify navigation mistakes, how to spot each one, and the cleanest way to fix it.
One number worth keeping in mind before we get into the details: according to Baymard Institute, the average cart abandonment rate in ecommerce is around 70%. Not all of it comes from navigation, but a portion of shoppers leave very early, before they even add to cart, simply because they got lost.
Mistake 1: Too many top-level menu items
This is the easiest mistake to make, because it comes from good intentions. The merchant wants shoppers to see everything, so they cram it all onto the main menu bar: a dozen or more top-level items, sometimes close to twenty.
The problem is that when everything is important, nothing is. The shopper looks at a long row, doesn’t know where to start, and so usually doesn’t start at all.
Spotting it is pretty simple. Open the homepage on desktop and count the top-level items. If the menu has to wrap to a second line, you’re overloaded. On mobile, if the top-level list runs longer than one screen and still isn’t done, that’s a sign too.
The fix: group related items together. A fashion shop doesn’t need “T-shirts,” “Dress shirts,” and “Jackets” as separate top-level items — fold them into “Tops” and put the types inside. Keep the top-level menu to around 5 to 7 items so shoppers can scan it in a second or two.
Mistake 2: No mega menu for a store with many categories
Once you’ve grouped things neatly, the opposite problem appears: the subcategories get buried too deep. The shopper has to click “Tops,” wait for the page to load to see what types there are, then click again. Every extra click is another chance for them to give up.
This is where the mega menu earns its keep. A mega menu is a large, multi-column dropdown panel that shows the entire category structure the moment a shopper hovers, so they can jump from a top-level category down to a subcategory in a single move. For a broad catalog, this is almost the default standard on large retail sites.
How to tell your store needs a mega menu: if shoppers have to click three or more times to reach a product listing page, or you have many subcategories with no way to see them all at once, that’s a sign.
One note when building a mega menu: if the panel has no hover delay, it will flicker every time the mouse accidentally passes over it. If you use a menu builder, choose one that handles this for you. Navi+ (https://naviplus.io) builds mega menus for desktop with drag and drop, no code required, so you don’t have to worry about that technical detail yourself.
Mistake 3: Relying only on the hamburger menu on mobile
Most shoppers in Vietnam shop on their phones, so this is the most expensive mistake. Many stores push all navigation into a three-line icon in the corner — a hamburger-style Shopify menu — and call it done. But hiding everything means shoppers have to actively open it to see anything, and most don’t bother.
Nielsen Norman Group once tested this on both phones and desktops. The result: when navigation is hidden, shoppers have a harder time finding the item they need, move slower, and rate the search as harder than when the menu is shown clearly. In other words, what shoppers can’t see effectively doesn’t exist to them.
How to spot it: open your store on your own phone. If reaching your best-selling category means tapping the hamburger, scrolling, then tapping again, picture a shopper in a hurry, standing while waiting for a ride.
The fix isn’t to drop the hamburger, but to bring the important paths out into the open, where a thumb can reach them without opening anything. A fixed Tab Bar at the bottom of the screen — like the apps shoppers use every day — keeps Home, Categories, Search, and Cart right in the thumb zone. This is the kind of menu Navi+ builds specifically for mobile, configured separately from desktop, so you keep the hamburger for the secondary stuff and let the Tab Bar handle the essentials.
Mistake 4: No breadcrumbs or location indicator
Shoppers browse deep into the catalog and forget where they are. They land on a product page through an ad or a search, like the item, but want to see more similar products — and there’s no natural way to step back up to the parent category.
A breadcrumb is a small trail like “Home > Tops > T-shirts > Men’s T-shirts” placed above the product name. It answers two questions at once: where am I, and how do I step back one level. It sounds simple, but many Shopify themes don’t enable it by default, or merchants remove it because it looks “cluttered.”
How to spot it: open any product page and ask yourself, “where do I click to see products of the same type?” If the answer is the browser’s Back button, you’re missing a location indicator.
The fix: enable breadcrumbs on category and product pages. Also, make the current item clear on the main menu — for example, bolding or underlining the active category — so shoppers always know which branch they’re on.
Mistake 5: Categorizing by the merchant’s logic, not the way buyers think
This is the most subtle mistake, because the menu still looks tidy. The problem is in how the groups are set up. Merchants tend to categorize the way the warehouse or supplier organizes things, while buyers think in terms of their needs.
A familiar example: a cosmetics shop splits the menu by brand because that’s how they buy stock. But shoppers usually don’t remember brand names — they come to find “sunscreen” or “matte lipstick.” When the menu has no path by purpose, shoppers have to guess which brand carries what they need, and most give up.
Baymard groups miscategorized navigation among the high-impact navigation problems, because it leaves the impression that a store is hard to use.
Spotting it is harder than the previous four mistakes because it requires listening to shoppers. Reread the messages and questions shoppers often ask: if many people message “do you sell X,” when X is clearly available on the site, they almost certainly couldn’t find it through the menu. That’s a menu speaking your language, not theirs.
The fix: name items by the words shoppers use, not internal jargon. You can keep both axes — browse by product type and browse by purpose or occasion — if your shoppers think in different ways. The fastest way to check is to ask a few outsiders who’ve never been to your store to find a specific item, and watch where they click first.
A general note: don’t trade away speed
When fixing navigation, there’s a trap: you add an app, add effects, and the page slows down. Each app can pull in scripts that weigh the page down.
Google sets the “good” threshold for page load experience at LCP under 2.5 seconds, INP under 200ms, and CLS under 0.1. A beautiful menu that makes the page stutter, shift its layout, or respond slowly does more harm than good. When choosing a menu builder, prioritize one that cares about Core Web Vitals — this is also what Navi+ optimizes for, and the menu stays put when you change themes, so you don’t have to rebuild it from scratch every time you swap your design.
All five mistakes above can be fixed without knowing any code. Start with the one that affects the most shoppers on your store — usually the mobile side — and work your way down.
