Most ecommerce stores don't have a traffic problem — they have a conversion problem. Thousands of visitors arrive each month, browse, and leave without buying, and the owner's instinct is to buy more ads to feed more visitors into the same leaky funnel. But moving your conversion rate from 1% to 2% doubles your revenue without spending an extra penny on traffic. This guide covers the practical levers UK ecommerce stores actually use to lift conversion: what to fix first, what the data says works, and what to ignore until the basics are right.
Know your baseline before you change anything
You can't improve what you don't measure. Before touching anything, establish your current conversion rate (orders divided by sessions), your average order value, and your revenue per session. UK ecommerce conversion rates vary enormously by sector — fashion and general retail behave nothing like high-ticket furniture or B2B supplies — so don't obsess over matching a published "average". Your baseline is your last 90 days. Track it weekly, segment it by device and traffic source, and you'll quickly see where the leaks are: mobile converting at half the rate of desktop is the most common finding, and the most fixable.
If you want the full methodology behind this kind of work, our guide to improving conversion rates covers the research-and-test process in detail.
Fix the product page first — it's where money is made
The product page is the highest-leverage page on your store. The fixes that consistently move the needle:
- Photography that answers questions: multiple angles, zoom, lifestyle shots, and — for anything sized, worn or assembled — imagery showing scale. Shoppers can't pick the product up; every unanswered question is a reason to leave.
- Price honesty: show the full price early, including delivery, or at least make delivery costs findable before checkout. Unexpected shipping costs at checkout remain one of the top abandonment reasons in UK ecommerce.
- Stock and delivery clarity: "In stock, order before 2pm for delivery tomorrow" converts. Vague availability doesn't. If you can't promise a date, say so plainly — shoppers prefer honesty to hope.
- Reviews where they matter: product-level reviews near the buy button, not buried three scrolls down. They don't need to be perfect — a 4.6 average with honest critical reviews converts better than a suspicious wall of five stars.
- One clear call to action: the add-to-basket button should be unmissable and unambiguous. Every competing button on the page is a small tax on conversion.
De-risk the purchase
Online shoppers are managing risk: will it arrive, will it be as described, what if it's wrong? Every element that reduces perceived risk lifts conversion. Clear returns policy (stated in plain English near the buy button, not hidden in legal pages), secure checkout signals, recognised payment options including digital wallets and buy-now-pay-later where appropriate for your audience, and a reachable customer service presence — a phone number or live chat, not just a form. For higher-ticket items, guarantees and warranties deserve prominent placement, not a footnote.
Speed is a conversion feature
Slow pages don't just annoy — they directly suppress conversion, and the effect is worst on mobile, where most UK ecommerce traffic now sits. Compress images (WebP where supported), lazy-load below-the-fold content, strip unused apps and scripts — Shopify and WooCommerce stores accumulate speed-killing plugins like barnacles. Test on a mid-range phone on 4G, not your office fibre; that's your customer's reality. Our conversion rate optimisation work almost always starts with a speed audit, because it's the rare fix that's both cheap and high-impact.
Checkout: where revenue goes to die
Cart abandonment rates in the region of 70% are normal — but "normal" still leaves enormous money on the table. The practical fixes:
- Guest checkout as standard. Forcing account creation is a conversion killer; offer account creation after purchase.
- Fewer steps, fewer fields. Every field you remove helps. Do you really need a fax number and "how did you hear about us" before someone pays you?
- Show progress. A three-step checkout with a progress indicator feels shorter than a one-page form that scrolls forever.
- Recover abandoned carts. A well-timed email sequence recovers a meaningful share of abandoners — the first email within an hour performs best. This is the single highest-ROI automation most stores don't have.
- Mobile-first checkout. Large tap targets, autofill-friendly fields, digital wallets front and centre. If your checkout is painful on a phone, you're taxing your biggest traffic segment.
Test in order of impact, not opinion
The graveyard of CRO is full of tests on button colours. Prioritise by expected impact times ease of implementation: value proposition clarity, pricing and delivery presentation, product page content, checkout friction, then the cosmetic stuff. Run one test at a time on pages with enough traffic to reach a conclusion, and let tests run full weekly cycles — UK shopping behaviour differs between weekday and weekend, and ending a test on a Friday gives you a false read.
If this feels like a lot to run in-house, that's what specialists are for. Our ecommerce growth team runs structured testing programmes for UK stores — research first, then a prioritised roadmap of tests, not random tweaks.

FAQs
What is a good conversion rate for a UK ecommerce store?
It depends entirely on sector, price point and traffic mix — there's no single "good" number. Rather than chasing a benchmark, focus on your own trend: is your rate improving month on month? A store moving from 1.2% to 1.8% has achieved something far more valuable than a store sitting flat at an "above average" 2.5%. Segment by device and source; aggregate averages hide the real story.
What's the fastest way to increase ecommerce conversion?
The quickest wins are usually: fixing mobile page speed, adding guest checkout, clarifying delivery costs before checkout, and launching an abandoned-cart email sequence. None requires a redesign, all can be done in weeks, and together they routinely deliver the biggest first lift. Save the redesign for after the basics are working.
Do discounts increase conversion rates?
Usually yes in the short term, but they're expensive and they train customers to wait for the next sale. Before discounting, try removing friction (speed, checkout steps, delivery clarity) and reducing risk (returns, guarantees, reviews) — these lift conversion without eroding margin. Use discounts strategically, e.g. in cart-abandonment emails, not as the default lever.
How long does CRO take to show results?
Quick fixes can show results in weeks. A proper testing programme needs 3–6 months to compound — each test teaches you something that sharpens the next one. Be wary of anyone promising to double conversion in a month; sustainable lifts come from systematic testing, not silver bullets.
Should I redesign my store or optimise what I have?
Optimise first, almost always. A redesign resets all your learnings and often drops conversion initially as returning customers adjust. Redesign when the platform or UX is fundamentally limiting you — not when you just want it to look fresher. The prettiest store in your sector means nothing if the checkout still leaks.
