UX Spotlight: Superior Checkout Experience – Conversion or bust

In the UX Spotlight series, we explore standout digital experience features from across the web, offering inspiration for teams looking to reduce friction and build more intuitive customer journeys.

Checkout is still the moment of truth for every ecommerce site. You've done the hard work—brought shoppers in, earned their interest, and guided them to the cart. Now comes the part where most of them leave.

Retail conversion declined -5.5% in 2026, according to the Contentsquare Digital Experience Benchmark, and retail shopping sessions are getting shorter, not longer. Shoppers arrive with higher expectations and less patience. They want checkout to be fast, clear, and reassuring—and when it isn't, they're gone.

The good news: checkout is also the highest-leverage place to invest in your UX. Small improvements here have an outsized effect on revenue. As Jack Deegan, Senior Strategic Consultant at Contentsquare, puts it: "We used opportunity scoring to identify checkout as the area with the highest friction and the greatest potential for impact, so the roadmap started there."

This week, we look at three principles—personality, simplicity, and transparency—and the brands that get them right.

Key insights

• Retail conversion declined -5.5% in 2026, reinforcing checkout as the highest-stakes moment in the digital journey.

• 77% of retail visits come from mobile, yet desktop conversion rates remain 40–70% higher across every retail sub-industry—a gap that points directly to mobile checkout friction.

• Teams that use Digital Experience Analytics (DXA) frequently see up to +10% higher mobile web conversion rates (+17% for returning visitors).

• Looping behavior—shoppers moving back and forth through checkout steps—is a measurable signal that something isn't working, often before it shows up in exit data.

• Checkout isn't just about removing friction. It's an opportunity to reinforce your brand, build trust, and increase cart value—all in the same flow.

1. Personality: Checkout That Feels Like Your Brand

You know when a waiter says "great choice" after you order, and it makes you feel just a little more certain you made the right call? Checkout can do that too.

Threadless, the t-shirt company built around customer-designed apparel, understood this well. When you added an item to your cart, the cart thanked you—quirky, animated, on-brand. It winked. It licked its lips. A small detail, but one that made the shopping experience memorable and the next step feel inviting.

The principle here is still relevant in 2026: every step in the checkout flow should feel like it belongs to your brand, not like a generic transaction interface bolted onto your site. Micro-interactions—confirmation messages, loading animations, add-to-cart feedback—are small moments that can reduce anxiety, build confidence, and make shoppers feel good about continuing.

For brands with strong personalities, lean into them here. For brands built on trust and clarity, let that shine through in the language and layout. Checkout is not a place to go quiet.

2. Simplicity: Remove Every Step You Don't Need

The biggest source of checkout abandonment isn't pricing—it's friction. Every extra step, every forced account creation, every form field that could be auto-completed is a hurdle your shoppers might not clear.

Threadless addressed this early by defaulting to guest checkout and condensing the entire process onto a single screen. Both choices are now standard expectations, not differentiators. But brands still get this wrong.

Warby Parker pushed form-filling even further with an autofill feature that could guess a complete delivery address from just a few characters—a small detail that removed significant effort from a tedious step.

In 2026, this principle extends further. With 77% of retail visits happening on mobile, checkout must be designed mobile-first, not mobile-adapted. That means large tap targets, minimal keyboard switching, express payment options (Apple Pay, Google Pay, Shop Pay), and no unnecessary screens between "add to cart" and "order confirmed." Every additional step is a drop in conversion probability.

When easyJet Holidays identified problems in their checkout flow, the signal was behavioral: "We spotted looping behavior—customers going back and forth—a clear signal that something wasn't working," says Joseph Vinson, Product Manager at easyJet Holidays. Looping in checkout often means shoppers are looking for information they can't find, or reassurance they haven't received. Simplicity isn't just about fewer steps—it's about making the right information available at the right moment, so shoppers never feel the need to backtrack.

3. Transparency: Answer the Questions Before They're Asked

British appliance retailer AO.com has long been a standout example of checkout done right—not by stripping it down, but by adding value at exactly the right moment.

When you check out with a major appliance on AO, checkboxes appear for relevant add-ons: installation, old appliance removal, extended warranty. These aren't intrusive upsells—they're genuinely useful options that address the logistical concerns a customer is already thinking about. Offering them at checkout says: we know what buying a fridge actually involves, and we've made it easy.

AO also lets customers choose a delivery date and time, with transparent pricing for each option. No hidden fees at the final screen. No surprises.

This approach—proactive transparency—is one of the most powerful things checkout UX can do. Unexpected costs, unclear delivery timelines, and hidden terms are among the most common reasons shoppers abandon just before completing a purchase. Addressing them clearly, in plain language, removes doubt and builds the trust that closes the sale.

The language matters too. AO speaks to shoppers the way a knowledgeable in-store salesperson would—accessible, friendly, straightforward. That tone should run throughout checkout. Legal jargon and passive voice have no place in a flow where confidence is everything.

The Takeaway

The brands that get checkout right aren't necessarily the ones with the most sophisticated technology. They're the ones who have done the hard thinking about who their customer is, what they're worried about, and what would make the next step feel easy.

Threadless shoppers want a fun, frictionless experience that matches the brand's personality. Warby Parker customers want function and elegance, in their glasses and in their checkout. AO buyers want to know that a major purchase is completely taken care of.

In 2026, checkout optimization starts with data. Where are your shoppers hesitating? Where do they loop back? Which steps see the highest exits? Behavioral analytics, Session Replay, and funnel analysis can answer all of these questions—and turn checkout from your biggest leak into your biggest opportunity.
