Here's the thing about a flat conversion rate: it doesn't feel like an emergency. Traffic is coming in, the site is working, orders are trickling through. But when you do the maths, the gap between visitors and buyers is usually far bigger than it should be.
That gap is where revenue is disappearing. Not because your product is wrong, not because your prices are off -- but because somewhere between someone landing on your site and reaching the checkout, something is getting in the way.
The frustrating part, and something I see in almost every audit, is that internal teams almost always look in the wrong place first. A new homepage layout. A discount code. Another round of ad creative. These things occasionally help, but they rarely fix the underlying problem -- because the underlying problem is usually the experience itself.
What your conversion rate is actually telling you
Your conversion rate is the percentage of visitors who complete a purchase. Simple enough. But the number on its own doesn't tell you much without context.
IRP Commerce's April 2026 market data puts the global ecommerce average at around 1.7%. Dynamic Yield's benchmark sits closer to 2.66%. Shopify's research suggests that stores converting above 3.2% are in the top 20%, and above 4.7% puts you in the top 10%. These figures vary because each source measures a different slice of the market -- different industries, different store sizes, different methodologies.
What matters more than the specific number is where your rate sits relative to your category. A food and beverage store shifting low-cost, repeat-purchase products will naturally convert much higher than a furniture store where every order is a £400 considered decision. Comparing the two against the same benchmark tells you nothing useful.
But if you're sitting well below 2% and you're not in a high-consideration, high-value category, something in your experience is working against you. The question is what, and where. That is exactly what an ecommerce UX audit is designed to find.
The problem with not knowing where to look
Most store owners who come to me with flat conversion rates have already tried a lot of things. And they're not wrong to have tried them. The issue is that without knowing where in the funnel people are actually dropping off, you're essentially guessing.
There's a quick diagnostic split that helps here.
If your add-to-cart rate is low, the product page isn't doing its job. The images might be weak. The description might not address what people actually need to know before they commit. The price might appear without enough context to justify it. Or the page might just load too slowly, losing people before they've had a chance to decide.
If your add-to-cart rate is healthy but your overall conversion rate is low, the checkout is where things are falling apart. People are interested enough to pick a product, but something between the basket and the payment confirmation is putting them off. Unexpected delivery costs. Too many form fields. A payment method they don't recognise. More steps than they expected.
If returning customers convert well but new visitors don't, that's a trust problem. Repeat buyers already know you. First-time visitors don't have that reassurance -- and if your social proof, returns policy, and delivery information aren't prominent and credible, they'll hesitate and leave without ever reaching the checkout.
Each of these has a different fix. Which is why diagnosing the right one first saves a lot of time and money.
The five things that kill ecommerce conversions most often
Across the ecommerce sites I audit, the same friction points come up again and again. None of them are surprising. Most of them are entirely fixable.
Surprise costs. Baymard Institute analysed 48 separate studies to arrive at an average global cart abandonment rate of around 70%. One of the most consistent findings is that unexpected charges -- delivery fees, handling costs, or taxes appearing for the first time on the payment page -- are a leading cause of abandonment. The cost itself often isn't the issue. Shoppers can accept a £6.99 delivery charge. What they struggle to accept is seeing it for the first time after they've already decided to buy. It feels like a bait and switch.
Forced account creation. Research consistently puts this at between 23% and 26% of checkout drop-offs. The shopper came to buy something, not to set up an account they'll probably never log into again. Guest checkout isn't a minor UX tweak -- it's a revenue decision.
Too many form fields. Baymard's checkout research found the average ecommerce checkout has around 11 form fields. Most stores need about six or seven to actually complete an order. Every field beyond that is friction with no upside.
"In almost every ecommerce audit I run, the checkout is where the most money is being left on the table. Not the homepage, not the product page. The checkout. And it's usually something completely fixable."

Page speed. A one-second delay in load time has a measurable negative effect on conversion rates. On mobile, where more than 60% of ecommerce traffic now arrives, this matters more. A product page that takes four seconds to load on a mid-range phone isn't a technical inconvenience -- it's the reason a sale didn't happen. Google's Core Web Vitals report is free and takes minutes to run. Most store owners are surprised by what it shows.
Mobile UX that hasn't been tested on an actual phone. Most stores are built and reviewed on a desktop screen. Tap targets that are fine with a mouse become frustrating to hit with a thumb. Checkout forms that are tidy on a laptop trigger the wrong keyboard on an iPhone. These aren't design failures. They're testing failures -- and they're costing real money.
Why your team probably can't see this
Your team has used your site hundreds of times. They know where the filters are, they know what the checkout looks like, they know your brand well enough to fill in any gaps the product descriptions leave. A first-time visitor knows none of that.
The confusion a new visitor feels when they can't immediately tell whether returns are free, or when the delivery estimate isn't visible until the payment stage, or when a button label is slightly ambiguous -- all of that is invisible to anyone who already knows the answers. It's not a criticism. It's just what familiarity does.
It's also the most common reason "we've tried everything" doesn't include fixing the actual problem. The things teams try tend to be the things they can see. The checkout flow that's been the same for three years doesn't get questioned because nobody notices it's hard to use.
A practical starting point
Pull your conversion rate by device in GA4. If your mobile rate is below 1.5% and desktop is above 3%, you have a mobile UX problem that's dragging your overall number down. Start there. If you want to understand what fixing that gap is actually worth in revenue terms, the No-Friction Lab ROI calculator will show you in about 30 seconds.
If your rates are low across the board, look at your funnel step by step. Where does the drop happen -- before add-to-cart, or after? That one question points you at either the product page or the checkout, and from there the investigation becomes much more specific.
If you're spending on paid traffic, check whether the page people land on matches the expectation set by the ad. A generic homepage behind a specific product ad will always underperform, regardless of how good the rest of the site is.
Where analytics stops and a UX audit starts
Analytics tells you where people are leaving. It doesn't tell you why. A page with a high exit rate is a symptom. The cause could be a confusing layout, a missing trust signal, a price without enough context, a broken element on mobile, or a form that's a step longer than it needs to be.
A UX audit goes through the site the way a first-time visitor would, applies structured evaluation at each stage, and identifies the specific reasons people are dropping off. The output isn't 40 issues ranked by severity -- it's the handful of changes most likely to move the number, with clear explanations of why each one matters.
Think of it as the layer between the data and the decision. If you're weighing up whether the investment makes sense, take a look at how much a UX audit costs and what you actually get -- it breaks down what different price points include. And if you want a clear picture of where your store is leaking revenue, our UX and CRO audit is the place to start.
