You’ve done the hard work. You drove the traffic, earned the click, and got the shopper to add something to their cart. Then they left. No purchase. No explanation. Just another abandoned session in your analytics.
This happens to most e-commerce stores more than 70% of the time. According to data from the Baymard Institute, the average documented cart abandonment rate sits at 70.19% — meaning for every ten customers who show genuine intent to buy, seven walk away empty-handed.
The good news? Most of them didn’t leave because they changed their mind about the product. They left because your checkout got in the way. And that’s entirely fixable.
This guide covers the seven highest-impact checkout optimisation changes that reduce cart abandonment, improve your ecommerce conversion rate, and recover revenue you’re already earning — just not collecting.
Why Shoppers Abandon: The Data and the Psychology
Before you fix the problem, it helps to understand what’s actually driving it. The Baymard Institute’s research identifies the top reasons shoppers abandon checkout:
- Extra costs (shipping, taxes, fees) revealed too late — 48%
- Being forced to create an account — 26%
- Slow or complicated checkout process — 22%
- Not trusting the site with payment information — 17%
- Insufficient payment options — 11%
Notice what’s missing from that list: price objections, competitor comparisons, and genuine product doubt. The overwhelming majority of abandonment is caused by friction, anxiety, and surprise — all of which you control.
Psychologically, checkout is the highest-stakes moment in the purchase journey. Shoppers move from browsing mode into decision mode, and any unexpected obstacle — a mandatory registration wall, a hidden shipping fee, an unfamiliar payment form — triggers hesitation. Once hesitation sets in, momentum breaks. And without momentum, most people don’t come back.
That’s the problem. Here’s how to solve it.
The 7 Checkout Optimisation Changes That Actually Move the Needle
1. Enable Guest Checkout (Non-Negotiable)
Forcing account creation before purchase is one of the most damaging things an e-commerce store can do to its conversion rate. The customer doesn’t want a relationship right now — they want the product. Demanding registration is like asking someone to join a loyalty programme before they’ve even tried the food.
Enable guest checkout as the default or primary option. You can still offer account creation, but make it optional and present it after the purchase is complete. Many customers will opt in post-purchase when they’re in a positive emotional state and can see the benefit clearly.
One major retailer — ASOS — reported a significant increase in completions after removing mandatory login as a prerequisite to purchase. The fix is simple. The impact is immediate.
2. Add a Progress Indicator
Uncertainty is a conversion killer. When shoppers can’t see how many steps stand between them and completing their order, anxiety builds. A simple progress bar — showing steps like Cart, Delivery, Payment, Confirmation — gives customers a sense of control and an end in sight.
Progress indicators reduce what UX researchers call “completion anxiety.” They work on the same principle as a loading bar: even if the total time is identical, people tolerate a known wait far better than an unknown one. Keep your checkout to three to four steps maximum, and label each one clearly.
3. Display Trust Signals at the Payment Stage
Payment information is where anxiety peaks. Shoppers who were comfortable browsing your store may suddenly hesitate when asked to enter card details. This is where trust badges do real work.
Place SSL certificates, recognised payment icons (Visa, Mastercard, PayPal), security seals, and short reassurance copy — such as “Your payment is 100% secure” — directly on the payment page and near the checkout button. Don’t bury them in the footer. Put them where eyes are already focused.
If your store has reviews or a strong return policy, surface both here. A visible “Free returns within 30 days” line next to the pay button can resolve the last-second doubt that kills conversions.
4. Expand Your Payment Options
Offering only card payments in 2025 is a meaningful conversion leak. Buy Now Pay Later options (Klarna, Afterpay, Clearpay), digital wallets (Apple Pay, Google Pay), and PayPal have each become expected by large segments of online shoppers.
BNPL options in particular have a strong effect on average order value as well as conversion rate — they make higher-priced items feel more accessible. Meanwhile, one-click digital wallets reduce checkout friction dramatically on mobile, where re-entering card details on a small keyboard remains a genuine barrier.
Audit which payment methods your target audience actually uses and ensure they’re available. Each additional relevant option removes a reason to leave.
5. Fix Your Page Speed
Every second of load time costs you conversions. Google’s research has consistently shown that the probability of a bounce increases sharply after the first two seconds of load time. At checkout — where the customer is at their most impatient — slow pages are particularly damaging.
Run your checkout flow through Google PageSpeed Insights and GTmetrix. Common culprits include unoptimised images, excessive third-party scripts, and unminified code. Prioritise performance improvements on your cart and checkout pages above all else — these pages generate revenue, while homepage aesthetics do not.
Target a load time under two seconds on both desktop and mobile, and review your checkout page performance regularly, not just at launch.
6. Optimise for Mobile Checkout
In most e-commerce categories, more than 60% of traffic now comes from mobile devices. Yet mobile conversion rates still lag behind desktop significantly — largely because many checkout flows were designed for desktop and scaled down poorly.
A genuine mobile checkout optimisation audit should cover: tap target sizes (buttons must be large enough to hit reliably), auto-fill compatibility for forms, numeric keyboards triggered automatically for phone and card number fields, and a checkout layout that doesn’t require excessive scrolling or zooming.
If your mobile checkout forces users to pinch, squint, or wrestle with dropdown menus, you are losing a significant percentage of your highest-intent visitors at the final step.
7. Implement Exit-Intent Recovery
Exit-intent technology detects when a user is about to leave the checkout page — typically by tracking cursor movement toward the browser bar — and triggers a targeted intervention. This might be a discount offer, a free shipping threshold reminder, or simply a reassurance message.
Used well, exit-intent overlays recover between 5% and 15% of abandoning visitors, depending on the offer and targeting. Used poorly, they feel intrusive and damage brand trust. The key is relevance: trigger them only on the checkout page, only for users who haven’t completed purchase, and test the messaging carefully.
Tools like OptiMonk, Klaviyo, and Privy all offer exit-intent functionality with e-commerce integrations. Pair exit-intent on-site with an automated abandoned cart email sequence for a two-layer recovery system.
How to Prioritise: Start Where You’re Leaking Most
Not every store has the same problem. Before implementing all seven changes at once, look at your analytics to identify where in the checkout funnel you’re losing people.
In Google Analytics 4, set up a checkout funnel exploration to see step-by-step drop-off rates. If you’re losing 40% of users at the account creation step, guest checkout is your priority. If drop-off spikes at the payment page, trust signals and payment options should come first. If mobile abandonment is dramatically higher than desktop, start there.
Fix the biggest leak first. Then work down the list.
Real-World Result: What a Focused Checkout Audit Can Deliver
A mid-sized UK apparel retailer with a monthly revenue of approximately £180,000 ran a focused three-month checkout optimisation programme. The changes implemented included: enabling guest checkout, adding a three-step progress indicator, introducing Apple Pay and Klarna, and launching a two-email abandoned cart sequence.
The result was a 23% increase in checkout completion rate and a 17% uplift in overall ecommerce conversion rate — delivering an estimated additional £30,000 in monthly revenue. No increase in ad spend. No product changes. Just a checkout flow that stopped getting in the customer’s way.
Tools to Help You Implement Each Change

Tracking Your Improvement
The primary metric to watch is your checkout completion rate — the percentage of sessions that reach the checkout page and result in a completed order. A secondary metric worth tracking is your overall ecommerce conversion rate, which contextualises checkout performance against total traffic.
Set a baseline before making any changes. Implement one or two improvements at a time where possible, so you can attribute impact accurately. Review weekly for the first month, then monthly once performance stabilises.
Small, consistent improvements compound. A checkout flow that converts at 55% instead of 45% — on the same traffic — can be worth tens of thousands in annual revenue.
Stop Paying to Lose Customers at the Last Step
Every pound you spend on paid traffic, influencer partnerships, or SEO ends at the checkout page. If that page is creating friction, anxiety, or surprise, you’re subsidising abandonment at scale.
The seven changes in this guide — guest checkout, progress indicators, trust badges, expanded payment options, page speed, mobile UX, and exit-intent recovery — are not experimental tactics. They are proven, widely validated improvements that directly reduce cart abandonment and improve your ecommerce conversion rate.
Pick the change that addresses your biggest drop-off point. Implement it this week. Then work through the rest methodically. The revenue is already there — your checkout just needs to stop turning it away.
