Technical Performance
Speed and performance optimization tactics for eCommerce. Glued's manifesto guidelines for faster, higher-converting stores.
Make Buying Easy with Clear Product Displays
If users have to navigate multiple pages—Product Detail Page (PDP), Cart, and Checkout—just to make a purchase, they may drop off before completing their order. A complicated journey leads to lost sales.
Make Categories Clickable for Easy Navigation
If category labels are not clickable, users may get frustrated trying to tap subcategories or navigate backward. This adds unnecessary friction and slows down the shopping experience.
User Experience, Technical Performance
When collection and product links look the same, users may struggle to differentiate between browsing a category and selecting a specific product. This can lead to frustration and an inefficient shopping experience.
Add a Primary Action in Mobile Navigation
On mobile, users may feel overwhelmed by multiple navigation options, leading to indecision and drop-offs. If they can't quickly determine where to go next, they may abandon the session entirely.
Use Collections as Main Navigation Dropdowns
If your store has a large number of SKUs, listing individual products in dropdowns will overwhelm users and make navigation cluttered. This slows down browsing and creates decision fatigue.
Make Categories Clickable for Easy Navigation
If category labels are not clickable, users may get frustrated trying to tap subcategories or navigate backward. This adds unnecessary friction and slows down the shopping experience.
User Experience, Technical Performance
When collection and product links look the same, users may struggle to differentiate between browsing a category and selecting a specific product. This can lead to frustration and an inefficient shopping experience.
Prioritize Primary Shopping Links
If all links in your navigation look equally important, users may struggle to find the main shopping paths. When primary and secondary links compete for attention, it creates confusion and slows down decision-making.
Keep Desktop Navigation Clean for Large SKU Catalogs
If you have a large number of SKUs, adding images to your desktop navigation can create visual overload, slowing down the browsing experience and making it harder for users to find what they need.
Keep Your Cart Fast & Lightweight
A slow or clunky cart experience can frustrate users, leading to abandoned purchases. Overloading your cart with heavy JavaScript or third-party apps can delay interactions, making it harder for users to proceed smoothly to checkout.
Keep Your Cart Clean & Easy to Scan
A cluttered or poorly structured cart makes it hard for users to review their selections and adjust their order, creating friction on what should be a simple process for readying to order to check out.
Make Cart Actions Simple & Intuitive
If users struggle to update quantities, remove items, or make changes in the cart, they may abandon their purchase out of frustration. A clunky cart experience creates unnecessary friction.
Display Cart Item Count for Clarity
Users need a clear visual cue to know how many items they have in their cart. If they can't see their selection or gauge how their cart is growing, they may lose track of their purchase or second-guess their checkout experience.
Use a 2-Column Layout for Info-Light Products
If your products don't require detailed descriptions or specs, a traditional single-column layout wastes space and slows down browsing. Users shouldn't have to scroll endlessly to find what they need.
Display Product Count for Better Search Context
If users don't know how many products are available in a collection or after filtering, they may feel lost or frustrated. Without product count visibility, they might assume there are too many (or too few) options and abandon the search.
Make Breadcrumbs Clickable for Easy Navigation
If breadcrumbs are static text, they lose their full potential as a navigation tool. Users may want to quickly jump back to a parent category without relying on the back button or reloading pages.
Make Filters Easy to Access & Use
If users have to dig through menus or scroll endlessly to find filters, they're more likely to abandon their search or leave frustrated. Quirky or hidden filters also slow down the shopping experience.
Enable Direct Add-to-Cart from Product Carousels
When users browse alternative products in a PDP carousel, making them click through to another page just to add an item creates unnecessary steps. This extra friction can lead to indecision or drop-offs.
Use Horizontal Space to Optimize Desktop UX
Many PDPs are designed with a mobile-first mindset, leading to excessive vertical scrolling on desktop. If content isn't properly structured, users may have to scroll too much to find key details, creating a frustrating experience.
Add Breadcrumbs for Easy Navigation
On sites with a large number of SKUs, users can quickly lose track of where they are. If they land on a product page from search or an ad, they may have no context for where the product sits within your catalog—making it harder to explore related items or return to a broader selection.
Keep Paragraph Width Readable on Desktop
On wide desktop screens, text that stretches too far across the screen becomes difficult to read. Long line lengths make it harder for users to track from one line to the next, leading to fatigue and frustration.
Embed Videos to Keep Your PDP Fast & Smooth
While product videos are great for engagement, directly uploading large video files to your PDP can slow down your site. Slow-loading pages frustrate users, hurt SEO, and increase bounce rates—especially on mobile.
Don't Neglect Desktop—It Still Needs to Convert
While mobile traffic dominates for many brands, desktop users often have higher purchase intent. If your PDP is optimized only for mobile—without considering desktop usability—you risk losing valuable conversions.
Group Product Information for a Natural Flow
Scattered product details force users to jump around the page, making it harder to find key information. When specs, benefits, and pricing are disorganized, users may get frustrated or miss crucial details—leading to drop-offs.
Add Carousel Arrows for Easy Image Navigation
Not all users instinctively know they can swipe through product images, especially on desktop. If navigation isn't clear, they might miss out on key visuals that could influence their purchase decision.
Make "Add to Cart" the Star of Your Product Page
A cluttered product detail page (PDP) with competing elements can distract users from the primary goal—adding the product to their cart. If the "Add to Cart" button is hard to find or overshadowed, users may hesitate or leave.
Remove Distractions—Focus on "Add to Cart"
Too many options—like alternative payment methods, wishlist buttons, or excessive links—distract users from the primary goal: adding the product to their cart. When users have too much to process, they hesitate or abandon the page.
Clearly Label Variant Selections
When users select product variants (e.g., size, color, style), they need clear confirmation of their choice. If the selection isn't obvious, they might hesitate or abandon the purchase due to uncertainty.
Ensure Variant Selectors Are Clickable & Clear
If variant selectors (e.g., size, color, style) don't look interactive, users may struggle to make selections or assume options are unavailable. Similarly, unclear selections can lead to errors and frustration.
Nest One-Time & Subscribe & Save Options Under Each Selection
If users have to navigate away or make extra clicks to see subscription options, many will default to a one-time purchase. This results in missed opportunities to increase lifetime value (LTV) and recurring revenue.
