1. What conversion rate should your store actually hit?
Before diagnosing a problem, you need a baseline. WebAnts is a London ecommerce development agency — the figures below reflect what we see across UK stores we audit, rebuild, and manage.
| Sector | Average CVR (UK) | Well-optimised CVR |
|---|---|---|
| Fashion & apparel | 1.5–2.5% | 3–5% |
| Health, beauty & wellness | 2–3.5% | 4–6% |
| Home & garden | 1.5–2.5% | 3–4% |
| Electronics & tech | 1–2% | 2.5–4% |
| Food & drink | 2–4% | 5–8% |
| Supplements & nutrition | 2.5–4% | 5–7% |
| Jewellery & accessories | 1–2% | 2.5–4% |
| Pet products | 2–3% | 4–5% |
If your store is converting below the average for your sector, you have a diagnosable problem. If you are below 0.5%, something structural is broken — it is almost never a product or pricing issue at that level.
How to find your conversion rate
In Google Analytics 4: Monetisation → Overview → Purchase conversion rate. In Shopify Analytics: Home → Conversion rate. If your rate is not visible, check your GA4 setup — most stores have broken purchase tracking and do not know it.
2. Reason 1 — Your store loads too slowly
This is the most common issue we find in ecommerce audits — and the most reliably fixable. Google data shows that a 1-second delay in mobile load time reduces conversions by up to 20%. A store with a 4-second load time is converting at roughly half the rate it would at 2 seconds, simply because a significant proportion of visitors leave before the page finishes loading.

Open Google PageSpeed Insights and enter your store URL. Test mobile separately — mobile scores are almost always worse and mobile is where most of your UK traffic arrives. A score below 60 on mobile is costing you conversions daily.
The most common culprits by platform
Shopify
- →Too many installed apps — each app adds 20–200ms of JavaScript load. Audit and remove any apps you are not actively using.
- →Large, uncompressed product images — Shopify serves images at full resolution unless you use the img_url filter with size parameters. Compress all images to under 200KB.
- →Bloated theme with animation libraries — many premium Shopify themes load multiple JavaScript animation frameworks. A custom theme eliminates this.
- →Missing lazy loading on below-the-fold images — the browser should not load images the visitor cannot see yet.
WooCommerce
- →Shared hosting — WooCommerce needs managed WordPress hosting (Kinsta, WP Engine, Cloudways) to perform. Shared hosting kills response times.
- →Plugin bloat — every active WooCommerce plugin adds server-side processing time. Each checkout extension adds client-side JavaScript.
- →No CDN — serving images and static assets from a single UK server instead of a global CDN adds 200–800ms to international visitors.
- →Unoptimised database — WooCommerce stores order data aggressively. Without regular database optimisation, queries slow down over time.

3. Reason 2 — The mobile experience is broken
Over 72% of UK ecommerce trafficarrives on mobile. If your store was designed desktop-first and “made responsive,” that is not the same as being designed mobile-first. The problems are different — and the conversion impact is severe.
Add-to-cart button not sticky
On mobile, the add-to-cart button should follow the user as they scroll down a product page. If they have to scroll back to the top to buy, most will not.
Product images too small or not swipeable
Mobile shoppers expect to swipe through product images like a gallery. A grid of thumbnails designed for desktop does not translate to mobile.
Text too small to read without zooming
Google's mobile usability guidelines require a minimum 16px font size for body text. Smaller text forces zoom, breaks layout, and signals an unmaintained site.
Checkout form fields too small to tap
Phone number, postcode, and credit card fields with 12px height on mobile result in mis-taps, frustration, and abandonment. Test your checkout on a real phone, not a browser emulator.
Pop-ups blocking the main content on load
Google penalises mobile pages where intrusive interstitials cover the main content. An email capture pop-up that fires immediately on mobile page load is both a CRO problem and an SEO problem.
No Apple Pay / Google Pay at checkout
One-tap checkout options reduce mobile abandonment dramatically. If your store requires manual card entry on mobile, you are leaving 15–25% of potential sales on the table.
4. Reason 3 — Your product pages are not doing enough work
The product page is where the buying decision is made. Most ecommerce stores treat it as a container for a photo, a price, and a button. The best-converting UK stores treat it as a sales page — with every element designed to reduce doubt and increase confidence.
What underperforming product pages look like
- ✗One product photo, usually a plain white background studio shot
- ✗Generic manufacturer description copied directly from a spec sheet
- ✗No size guide, no fit notes, no “how to use” information
- ✗Zero customer reviews, or reviews hidden below the fold
- ✗No indication of stock levels — “Add to cart” with no urgency signal
- ✗No cross-sell — the visitor either buys this item or leaves
- ✗Shipping information buried in the footer — not visible on the product page
- ✗Returns policy not mentioned until checkout
What high-converting product pages include
- ✓5–8 images: lifestyle shots, detail shots, in-use context, and scale reference
- ✓Video — even a 15-second looping product demo lifts conversions 15–25%
- ✓Benefit-led description in short paragraphs — not feature lists
- ✓Size guide, fit notes, or compatibility information inline on the page
- ✓Reviews displayed prominently with verified buyer labels and star distribution
- ✓Shipping estimate and returns policy visible above the fold
- ✓Stock scarcity signal — “Only 4 left” when genuinely low
- ✓Frequently bought together section with one-click add
- ✓Sticky add-to-cart bar on scroll
5. Reason 4 — The checkout has too much friction
The average UK cart abandonment rate is 70–75%. That means you are losing three out of four customers who have already decided to buy. The checkout is not a formality — it is a conversion event in its own right, and every extra step reduces the number of people who complete it.
| Friction point | % of UK shoppers who abandon because of this |
|---|---|
| Unexpected shipping costs at checkout | 56% |
| Forced account creation before purchase | 37% |
| Checkout process too long or complicated | 28% |
| Could not see the total order cost upfront | 25% |
| Website did not feel trustworthy enough | 24% |
| Not enough payment methods available | 19% |
| Card declined — no retry mechanism shown | 11% |

The five highest-impact checkout fixes:
Show all costs (shipping, VAT, any fees) on the product page and basket — not for the first time at checkout.
Add guest checkout as the default. Account creation should be optional and offered after purchase completion.
Reduce to three steps maximum: cart → shipping details → payment. Any more than three steps measurably increases abandonment.
Add Apple Pay, Google Pay, and PayPal alongside card. The fewer keystrokes to payment, the higher the completion rate — especially on mobile.
Show trust signals at the payment step: SSL badge, accepted cards, your returns policy, and a phone number. This is where doubt peaks.
6. Reason 5 — Visitors do not trust you yet
UK consumers are increasingly cautious about buying from unfamiliar online stores — especially after a rise in ecommerce fraud. Trust is not earned by saying you are trustworthy. It is earned by displaying the specific signals UK shoppers look for.
Visible reviews
Display verified reviews from Trustpilot, Google, or Shopify Product Reviews. The number of reviews matters as much as the score — 4.7★ from 3 reviews is less convincing than 4.4★ from 847 reviews.
Clear returns policy
Display your returns window prominently — above the fold on product pages, not buried in the footer. “Free 30-day returns” displayed next to the price lifts conversions. Mention it again at checkout.
Registered company details
UK shoppers check for a registered company address and Companies House number. If your store lacks a physical address and company registration, a proportion of visitors will not complete the purchase.
SSL and security badges
Your padlock is not enough. Display payment security badges (Visa Secure, Mastercard Identity Check, Norton, McAfee) at the payment step. These address a specific anxiety at the moment it peaks.
Real product photography
Stock photography or AI-generated images signal inauthenticity. Real products, real environments, and real people wearing or using your products build trust that no badge or copy can replicate.
Active social presence
If a visitor checks your Instagram before buying and finds the last post was from 2023, the sale is likely lost. A live, recent social feed is a trust signal — link it from the footer and product pages.
7. Reason 6 — You are sending the wrong traffic
A conversion rate problem is sometimes actually a traffic quality problem. If your store converts at 0.3% but your bounce rate is 80% and average session duration is under 20 seconds, the visitors are not interested in what you are selling — not unable to buy it.
Ranking for informational keywords, not buying keywords
If your SEO drives traffic from searches like “how to care for leather shoes” to your shoe product pages, those visitors are researching — not buying. Informational traffic converts at 0.1–0.3%. Buying-intent traffic (e.g. “buy tan leather Oxford shoes UK”) converts at 3–8%. Check which keywords drive your highest-traffic pages in Google Search Console.
Google Ads broad match sending untargeted traffic
Google Ads broad match and even phrase match keywords in 2026 can serve your ads to tangentially related queries. If you sell premium dog food and your ads are showing for “dog food recipes,” those clicks cost money and convert poorly. Audit your search terms report monthly and add negatives aggressively.
Social media traffic with no buying intent
Instagram and TikTok traffic arrives in a browsing mindset, not a buying mindset. Conversion rates from social organic are typically 0.5–1.5% — far lower than search. If social is a major traffic source but conversion is low, the problem is the channel mix, not the store.
Wrong geographic audience
If you do not ship internationally but significant traffic arrives from the US, Australia, or the EU, those visitors cannot convert. Check your traffic breakdown by country in GA4 and exclude non-shipping territories from paid campaigns.
8. Reason 7 — Your navigation is working against you
Poor navigation does not just frustrate visitors — it actively prevents sales by making it harder to find products, harder to filter by what matters, and harder to pick up where you left off. These are the navigation failures we find most often in ecommerce audits.
No search bar or a search bar that returns poor results
Site search converts at 3–5× the rate of browse navigation. If your search returns irrelevant products or returns nothing on slight misspellings, replace it. Shopify's native search is weak — Searchie or Boost Commerce are better options.
Too many top-level categories
More than 7 top-level navigation items overwhelm visitors. Flatten the category structure and use mega menus or faceted filtering for depth.
No breadcrumbs on product pages
Breadcrumbs tell visitors where they are in the store structure and make it easy to browse similar products. Missing breadcrumbs increase exit rates from product pages.
Filtering options that do not match how customers think
If you sell supplements, customers filter by goal (weight loss, muscle gain, sleep) — not by format or brand. If you sell homewares, they filter by room and colour — not by material or SKU. Your filter structure should mirror how customers shop, not how your database is organised.
No recently viewed or wishlist functionality
Shoppers frequently browse, leave, and return. Without a recently viewed section or wishlist, returning visitors start from scratch — and many do not make it back to the product that interested them.
9. Reason 8 — No urgency, no reason to buy today
The default state of an online shopper is deferral. “I will come back to it.” In most cases, they do not. Without a reason to act now, visitors who are genuinely interested in your product will close the tab, intend to return, and forget. These are ethical, non-manipulative urgency signals that work.
Real stock scarcity
Display remaining stock count when genuinely low — “Only 3 left in this size.” Never fake this. Shoppers are savvy and false scarcity destroys trust permanently.
Delivery cutoff countdown
“Order in the next 2h 14m for guaranteed next-day delivery.” This is one of the highest-converting urgency elements in UK ecommerce — particularly for gifts and time-sensitive purchases.
Free shipping threshold progress bar
“Add £8.50 more for free shipping.” A progress bar showing how close the customer is to the free shipping threshold lifts average order value by 10–20% and reduces abandonment.
Restock notification
On out-of-stock items, capture the email address with “Notify me when back in stock.” This builds your email list and recovers demand that would otherwise be permanently lost.
Limited edition / seasonal framing
If a product genuinely is seasonal or limited, say so explicitly. Seasonal framing (not fake countdown timers) is a legitimate and effective conversion signal.
Visible social proof of demand
“47 people are viewing this right now” and “Bestseller — 1,200+ sold” create perceived demand. Only display figures that are real and meaningful.
10. Reason 9 — Your platform is the bottleneck
Sometimes the problem is not what is on the store — it is the platform itself. No amount of copy optimisation or image improvement fixes a platform that is structurally slow, inflexible, or limited.
Wix or Squarespace stores
The problem: Wix and Squarespace ecommerce are built for simplicity — not conversion performance. Both have limited checkout customisation, no one-step checkout, restricted app ecosystems, and Core Web Vitals scores that are difficult to improve past a ceiling.
The fix: Migration to Shopify is the standard move for any UK store doing over £5,000/month in revenue. Shopify's checkout converts at a higher baseline rate than any drag-and-drop builder.
WooCommerce on shared hosting
The problem: WooCommerce is powerful but demands proper server resources. On shared hosting, PHP processes queue, database queries time out, and pages serve inconsistently — particularly during traffic spikes. The store works fine when you test it but falls apart when it matters.
The fix: Move to managed WordPress hosting (Kinsta, WP Engine, or Cloudways) before spending any more on CRO. The hosting upgrade alone typically improves conversion rates noticeably.
Shopify with a bloated third-party theme
The problem: Many premium Shopify themes are built to look impressive in demos — not to convert at scale. They load 15–20 JavaScript files, use multiple animation libraries, and have layout structures that prioritise visual flair over conversion hierarchy.
The fix: A custom Shopify theme built to your store's specific needs eliminates unused code, improves LCP to under 1.5 seconds, and structures every page around conversion rather than aesthetics.
Magento (Adobe Commerce) legacy
The problem: Magento stores built before 2022 are often running outdated PHP, have no CDN, and require significant developer investment just to maintain — let alone improve. The conversion ceiling on unmaintained Magento installs is severe.
The fix: Migration to Shopify Plus or a headless Next.js + Shopify setup delivers significant conversion and performance improvements for mid-size to enterprise UK stores.
If a platform migration is the right call for your store, our ecommerce development service covers migrations, rebuilds, and custom Shopify development for UK brands.
11. Reason 10 — You are losing customers after they leave
Most first-time ecommerce visitors do not buy on the first visit. The question is whether you have the systems to bring them back. Without them, the majority of your marketing spend is building an audience that buys once — from someone else.
Abandoned cart email sequence
A three-email abandoned cart sequence (1 hour, 24 hours, 72 hours) recovers 5–15% of abandoned carts. Email 1 is a simple reminder. Email 2 adds social proof. Email 3 offers a small incentive. If you have no abandoned cart automation, you are losing a recoverable revenue stream every day.
Post-visit retargeting (Meta / Google)
Visitors who do not convert on the first visit have already expressed intent. Meta and Google retargeting campaigns targeting these visitors convert at 2–5× the rate of cold traffic — at a fraction of the CPM. If you are not retargeting, your paid media spend is funding your competitors' remarketing pools.
Email list capture on exit
An exit-intent overlay offering a small discount (10% off, free shipping on first order) in exchange for an email address converts 2–5% of exiting visitors into email subscribers. Each subscriber has a lifetime value multiple times that of a one-time purchaser.
Post-purchase sequence
The easiest customer to convert is one who has already bought. A post-purchase sequence that requests a review (Day 7), suggests a complementary product (Day 14), and offers a loyalty incentive (Day 30) is the highest-ROI email programme most UK stores are not running.
12. Reason 11 — The design has lost credibility
Design is not about aesthetics — it is about trust. Studies consistently show that visitors form a trust judgement about a website within 50 milliseconds of arrival. An outdated design signals an outdated business. These are the design credibility failures we most commonly see in UK ecommerce store audits.
Generic stock photography — the same images your competitors use, downloaded from the same databases
Default theme fonts and colour palette — no brand differentiation, no visual identity
Inconsistent spacing, misaligned elements, or layout that breaks on certain screen sizes
Product photography with inconsistent backgrounds — some white, some lifestyle, some blurry
No brand story — the About page is either missing or a boilerplate paragraph
Footer cluttered with dead links and placeholder text from the original theme setup
Outdated badge graphics — “SSL Secure 2019” icons, old Visa/Mastercard logos
Design credibility is the hardest problem to fix incrementally because every element of the visual design is load-bearing. A partial visual refresh rarely solves it — the inconsistencies between refreshed and unrefreshed sections often make the trust problem worse. If your store has a design credibility problem, a full redesign is the right answer.
13. Rebuild or fix? How to decide
Not every underperforming store needs a full rebuild. The right answer depends on where the problem sits in the stack. Here is a simple framework we use at WebAnts when a client comes to us with a conversion problem.
Fix without rebuilding
£500 – £4,000Your conversion rate is 1–2% and you have identified specific friction points from GA4 funnel data. The platform is fundamentally sound (not Wix, not shared hosting). You need targeted fixes: checkout improvements, product page copy, trust signal additions, speed optimisation.
Appropriate for: individual CRO fixes, speed passes, trust signal audits, checkout redesigns on existing stores.
Partial rebuild — keep the platform, rebuild the theme
£4,000 – £10,000Your conversion rate is below 1% and the platform is good (Shopify, well-hosted WooCommerce) but the theme is the bottleneck — bloated, slow, and visually dated. A custom theme rebuild on the existing platform restores performance and design credibility without migrating product data.
Appropriate for: Shopify stores with slow or generic themes, WooCommerce stores where the platform is correctly configured but the theme is dragging performance.
Full rebuild — new platform, new design, new code
£5,500 – £25,000+Your conversion rate is below 0.5%, the platform itself is the bottleneck (Wix, Squarespace, Magento, shared WooCommerce), or the store has multiple issues across speed, design, trust, and checkout that make incremental fixes uneconomical. A full rebuild is a business investment — the ROI calculation is straightforward when you model the revenue at a 2× conversion improvement.
Appropriate for: stores doing £5,000+/month on the wrong platform, stores with conversion rates under 0.5%, stores that have accumulated too many partial fixes to have a coherent user experience.
The ROI calculation — a worked example
Monthly revenue at 0.8% CVR (1,000 visits × £60 AOV): £480
Monthly revenue at 2.5% CVR (same traffic, same AOV): £1,500
Monthly revenue uplift: £1,020
Cost of a Shopify theme rebuild: £6,000
Payback period: 6 months
This is a conservative example with low traffic. At £5,000+/month in revenue, the payback period shrinks to weeks, not months.
