Conversion rate optimisation agency, UK — recover the sales you're already losing

Most visitors leave your website without buying: across online retail, an average of 70.22% of shopping baskets are abandoned (Baymard Institute, from 50 studies). Conversion rate optimisation (CRO) finds exactly where your visitors drop out, and why, then removes those barriers so more of them buy or enquire. It keeps the traffic you already pay for.

Who this is for

This page is for you if any of this sounds familiar:

  • You're getting visitors from ads, search or social, but not enough of them turn into orders or enquiries.
  • You've spent on traffic, and it feels like money arriving and then quietly leaking away.
  • Your basket-abandonment rate looks high and you don't know which part of the checkout is to blame.
  • You have Google Analytics, so you can see where people drop off — but not why, and you're tired of guessing at fixes.
  • You're a B2B business, not a shop, and you want more of your visitors to fill in the enquiry form or book a call.

We're a small UK business ourselves, so we know what it's like when every visitor is hard-won and the ad budget is finite. As a UK conversion rate optimisation agency, we treat CRO as the most capital-efficient lever most small businesses have, precisely because it works on the people who are already turning up.

What CRO actually is — and what it isn't

Your conversion rate is the percentage of visitors who take a desired action: a purchase, an enquiry, a sign-up, a phone call. The Nielsen Norman Group, one of the longest-standing names in usability research, defines it exactly that way, and adds an important point: the goal isn't to maximise the rate, it's to optimise it for the right action. Pushing people toward the wrong action looks good on a chart and helps no one.

So CRO is the discipline of diagnosing where users stop and why, then removing those barriers. It is not:

  • Buying more traffic. Paid ads cost money per visit, every time. A CRO improvement, once made, keeps working without a cost per click.
  • A vague "design refresh". Redesigns change how a site looks; CRO changes how a site performs, measured against a baseline. The two aren't the same thing, and a redesign with no measurement is a gamble.
  • A one-size checklist. The fixes that matter for your site depend on where your visitors actually drop out — which is why diagnosis comes first.

What this means for you: before anyone touches your site, the first question is "where are we losing people, and why?" — not "what shall we redesign?"

Why this matters for UK small businesses now

Online retail keeps taking a larger share of UK spending. According to the Office for National Statistics, online sales were 28.3% of all retail sales in December 2025, up from 28.0% the month before, with online sales values up 11.1% year-on-year against December 2024. (The ONS figures cover Great Britain, but the direction of travel is clear across the UK.)

At that scale, every percentage point of conversion you lose is a real revenue gap — and unlike advertising, the gains from fixing it persist without an ongoing cost per click. For a small business with a modest ad budget, that's the difference between renting customers and keeping them.

What this means for you: the revenue is already arriving at your door. The question is how much of it leaks away before checkout.

Where conversion leaks happen

Most lost sales aren't a mystery. Independent research has mapped the same failure points across hundreds of sites, year after year. The Baymard Institute, an independent UX research body, has built one of the largest datasets of its kind: over 200,000 hours of research across 18,000+ users and 90+ leading US and European sites, including 4,400+ moderated "think-aloud" sessions, with 250+ top e-commerce sites benchmarked against 700+ UX guidelines. Here's where it consistently finds the leaks.

1. Navigation and the homepage — can people find their way in?

According to Baymard's navigation research (updated September 2025), 58% of desktop and 67% of mobile e-commerce sites have mediocre-to-poor homepage and category navigation, and 95% of sites don't indicate the user's current scope within the main navigation, so people lose their bearings and give up. The Nielsen Norman Group's eye-tracking work adds a related point: users spend about 57% of their viewing time above the fold and 74% within the first two screenfuls (from over 130,000 eye fixations, 2018), so what you put at the top of the page does most of the work.

2. Product pages — do they answer the buying questions?

Baymard's product-page research (March 2026) found 52% of desktop and 62% of mobile sites have mediocre or worse product-page experiences, with no site achieving a perfect rating. The recurring failures are specific and fixable: for example, 44% of sites don't display or link to the return policy from the main product-page content — even though 60% of users go looking for return information there before they decide to buy.

3. Site search — can people find what they came for?

Roughly half of e-commerce users rely on site search as their main way of finding a product (the other half use the navigation), per Baymard's search research (April 2026). Yet 56% of sites fail to adequately support what users search for, and 58% of mobile sites have mediocre or worse site-search experiences. People who can't find what they search for can't buy it.

4. Checkout — does the final step get out of its own way?

This is the highest-impact single zone. Baymard's checkout research (November 2025) found 64% of desktop and 63% of mobile checkout flows are mediocre or worse, with only 2% rated good. Part of the problem is sheer length: the average checkout in 2024 carried 11.3 form fields against an optimal of around 8, and 17% of users have abandoned a checkout simply because it was too long or complicated (Baymard, June 2024).

5. Page speed and Core Web Vitals — is the page quick to load and respond?

Core Web Vitals are Google's measures of real-world page experience: Largest Contentful Paint, or how quickly the main content appears (good is under 2.5 seconds); Interaction to Next Paint, or how fast the page responds when you tap or click (under 200 milliseconds); and Cumulative Layout Shift, or how much the page jumps around as it loads (under 0.1). These thresholds come from Google's web.dev guidance (October 2024), measured across real visitors. They're also one of the signals in Google's core ranking systems, one among many and not a dominant factor, so speed helps both conversion and search visibility.

The revenue link is documented in Google's own published case studies, as examples of what's possible rather than typical outcomes: after investing in Core Web Vitals, Rakuten 24 recorded a 33.13% increase in conversion rate and a 53.37% increase in revenue per visitor in an A/B test; Vodafone improved its Largest Contentful Paint by 31% and saw an 8% increase in sales; and redBus improved its Interaction to Next Paint and increased sales by 7%.

What this means for you: if the leading sites in these studies are mediocre or worse on checkout, search and product pages, the typical small-business site almost certainly has addressable problems too. The good news is that these are known, researched failure modes — not unknowable ones.

Trust is a conversion prerequisite

People don't buy from sites they don't trust, and distrust is measurable. Among shoppers who abandon a checkout (setting aside those just browsing), Baymard's 2025 data records the top reasons as: extra costs too high (39%); delivery too slow (21%); didn't trust the site with their card details (19%); required account creation (19%); checkout too long or complicated (18%); unsatisfactory returns policy (15%); website errors or crashes (15%); and couldn't calculate the total cost upfront (14%).

The Nielsen Norman Group identifies four factors that make a site feel credible (2016): design quality; upfront disclosure; being comprehensive, correct and current; and being connected to the rest of the web. In the same research, every participant said they would read reviews before deciding which company to hire — which is why authentic social proof matters. (It's worth testing how you present it: NN/g also found that visible engagement counts can backfire when they're low, and that third-party social widgets can noticeably slow a page, especially on mobile.)

There's a security dimension to trust as well. The National Cyber Security Centre (NCSC) guidance recommends publishing services only over HTTPS and redirecting unencrypted requests to the secure version — strong best practice rather than a legal mandate, but it's also the difference between a browser reassuring your visitor and warning them. UK shoppers recognise familiar payment-trust signals too, such as PCI DSS compliance and the major card-scheme logos.

What this means for you: a meaningful share of lost sales come down to confidence — clear costs, a visible returns policy, a site that loads cleanly and handles card details securely. Several of these are quick to fix.

How we approach CRO

We diagnose before we change anything. The method is deliberately the same one we run on our own site: we're a small business optimising our own conversion, not an agency handing down a checklist.

  1. Quantitative audit. We look at your analytics and map the funnel to find where people actually drop off, and we measure Core Web Vitals on your key landing and product pages. This is the "where".
  2. Qualitative diagnosis. We compare what your site does against the documented Baymard and Nielsen Norman Group failure patterns, so we can explain why people leave, not just where. Analytics tells you the where; this is the why.
  3. A prioritised fix list. We order the findings by expected impact against the effort to implement, so you start with the changes most likely to move revenue, not the easiest or the loudest.
  4. Implement, measure, iterate. We make the changes, measure against the baseline we took at the start, and keep the ones that work. Because we measure before and after, any uplift is visible and attributable, not a claim you have to take on faith.

What this means for you: you get a ranked, evidence-backed list of specific changes (and a measured before-and-after) rather than an expensive guess.

What we fix

CRO is surgical. We fix the things the diagnosis flags, and we deliberately avoid letting it sprawl into a full redesign you didn't ask for. Typical work, grouped by where the leaks tend to be:

  • Checkout flow. Simplifying the steps and reducing form fields toward the ~8-field optimum, and making the total cost (including delivery) clear before the final step.
  • Guest checkout. Making it the prominent option, so people don't wrongly assume they have to create an account. (More on why this matters in the FAQ below.)
  • Product-page trust signals. Surfacing shipping and returns information where buyers look for it, and making the buying questions easy to answer on the page.
  • Navigation and search. Helping people find products by both routes — clearer navigation and a site search that actually supports the way people search.
  • Core Web Vitals. Improving load and response times on the pages that carry the most traffic and revenue.
  • Forms (including B2B). Reducing enquiry-form length and friction so more visitors complete the action that matters to your business.

What this means for you: the brief is "find and fix what breaks the sale", scoped tightly — not "rebuild the site and hope".

Proof

Our position rests on the independent evidence above — Baymard's research scale and Google's own published speed-and-revenue case studies — applied to your site, with your own baseline measured before we change anything.

When we run your free CRO audit, you'll see exactly the kind of evidence we work from — your real funnel drop-off points and your Core Web Vitals scores — before you commit to anything.

How this fits your plan

CRO can run as a focused project — audit, prioritised fixes, measurement — or as ongoing work within your monthly plan, where we keep testing and improving over time. Lower-traffic sites take longer to gather statistically meaningful data, so the right shape depends on your traffic; we'll be straight with you about that up front.

Frequently asked questions

What is a conversion rate, and what counts as a good one?

Your conversion rate is the percentage of visitors who complete a desired action — a purchase, an enquiry, a sign-up. There's no single "good" number worth chasing: it varies a lot by industry, traffic source, device and price point, so a benchmark from someone else's business tells you very little. The measure that actually matters is the improvement against your own baseline, which is why we measure before and after.

We already have Google Analytics. Do we really need a CRO audit?

Analytics tells you where people drop off; it doesn't tell you why. A CRO diagnosis combines that quantitative data with qualitative UX research — the documented failure patterns from Baymard's 200,000+ hours of usability research — to explain the causes. Knowing the where without the why leads to guesswork fixes; pairing them is what turns data into the right change.

How much of basket abandonment can actually be fixed?

Not all of it — and we'll say so plainly. Some who abandon are simply browsing, and no amount of design recovers them. But the rest abandon for addressable reasons: unexpected costs, forced account creation, distrust, an over-long checkout. Baymard estimates the average large e-commerce site can gain a 35.26% increase in conversion rate through better checkout design alone — an average potential, not a promise, and a useful sense of the scale of what's recoverable.

Does page speed really affect sales?

Yes, with documented evidence from Google's own platform. After Core Web Vitals work, Rakuten 24 saw a 33.13% increase in conversion rate; Vodafone gained 8% more sales from a 31% improvement in Largest Contentful Paint; and redBus gained 7% more sales from improving Interaction to Next Paint. Google's thresholds (load under 2.5 seconds, response under 200 milliseconds, layout shift under 0.1) are also a ranking signal, so speed helps both conversion and search. These are named examples of what's possible, not typical outcomes.

Is CRO just about the checkout? What else does it cover?

Checkout is the single highest-impact zone, but it isn't the whole story. Baymard's research finds failures across navigation (58% of desktop sites mediocre or worse), product pages (52% desktop / 62% mobile) and site search (56% of sites inadequate). CRO covers the whole path from landing to purchase: first impressions, product discovery, the trust signals on product pages, and the checkout itself.

What quick wins usually produce the biggest uplift?

Based on Baymard's research, the highest-impact, lower-effort wins for most small-business sites are: making guest checkout the prominent option (47% of sites that offer it fail to, and 24% of US internet shoppers abandoned a basket in a single quarter solely because of forced account creation, per Baymard's 2022 survey); showing the total cost and delivery estimate near the buy button; linking the returns policy from the product page (44% don't, though 60% of users look for it there); trimming checkout form fields toward the ~8-field optimum from the 11.3-field average; and fixing Core Web Vitals on your key pages. None of these require a rebuild.

How long before we see results from CRO changes?

It depends on your traffic. Lower-traffic sites need longer to gather enough data to be confident a change really helped. For surgical, evidence-backed fixes, rather than a visual redesign, uplift can be observable within weeks on sites with meaningful traffic. We won't quote you a fixed timeline regardless of traffic; instead we measure before and after, so any uplift is visible and attributable to the change.

We're a B2B business, not an e-commerce shop. Does CRO apply to us?

Yes. CRO applies to any desired action — an enquiry form completed, a brochure downloaded, a demo requested, a call booked. The same principles carry over: trust signals, form length, page speed, a clear value proposition above the fold, and an obvious call to action. The Nielsen Norman Group defines conversion as any desired action, not only a purchase, and the same attention patterns (57% of viewing time above the fold) apply to your pages too.
