The ecommerce paradox

How ecommerce brands are winning at browsing — and failing at buying.

A 2-year analysis of 22,444 software issues reveals a critical disconnect between user experience and revenue-critical functionality.

Of all issues in the ecommerce checkout are critical, revenue-killing defects.


The core finding

Across two years of testing data, brands consistently prioritised aesthetics and feature delivery over reliability — and paid for it in lost conversions.

Our analysis of over 22,000 unique software issues across the ecommerce landscape uncovered a dangerous, counter-intuitive trend: brands are investing heavily in a complex, feature-rich “browse” experience at the direct expense of a stable, functional “buy” experience. This ecommerce paradox — where the site becomes less stable the closer a customer gets to paying — represents one of the single greatest, unaddressed digital risks for online retailers today.

01

The “browse” funnel is overwhelmed

62%
of all issues are found in the “browse” funnel — homepage, PLP & PDP

The modern ecommerce storefront — the homepage, product listing page (PLP) and product details page (PDP) — is a complex machine of personalisation engines, third-party review integrations and intricate filtering logic.

That complexity has made the browse experience a hotbed for bugs, damaging brand perception and frustrating users before they even reach the cart.

Brands are paying to drive traffic into broken journeys.

26%
PRODUCT DETAILS PAGE (PDP)
The #1 most problematic page in ecommerce.

19%
HOMEPAGE
The front door is the second-leakiest part of the house.

17%
PRODUCT LISTING PAGE (PLP)
Close behind the homepage in defect volume.

13%
CHECKOUT / ORDER CONFIRMATION
Lower volume, but far higher stakes per issue.

12%
PRODUCT SEARCH / FILTERS
A key discovery tool, and a frequent source of friction.

<3%
NAVIGATION / ACCOUNTS
The smallest share of total issue volume.

The takeaway
The customer’s discovery and research phase is riddled with the highest quantity of issues, creating a high-friction experience from the very first click.

02

The revenue funnel is the weakest link

40%
more likely for a bug found in checkout to be a critical, revenue-blocking defect than one found on the homepage

This is the central finding of the report. While the browse funnel has more bugs, the buy funnel has far worse bugs.

The data shows a sharp spike in severity the moment a user demonstrates intent to purchase — the very functions that capture revenue are the most likely to be critically broken.

The takeaway
The industry is failing at the one-yard line. The most valuable, conversion-focused parts of an ecommerce platform are also the most fragile and highest-risk — revenue-critical areas like checkout and basket fail over twice as often as discovery pages, exposing brands to preventable conversion loss.

The dual threat, and the solution

There is one area that represents a unique and urgent problem: the homepage. It’s the only functional area to appear in the top two for both high-volume issues and high-impact critical defects — the leaky front door, making a poor first impression and actively blocking users from starting their journey.

01

Protect the revenue — the “buy” funnel

Checkout, basket and account functions are non-negotiable. These areas demand rigorous, continuous regression testing and deep functional validation. Failures here aren’t just bugs — they’re lost revenue.

02

Manage the experience — the “browse” funnel

The homepage, PLP and PDP are high-volume, high-complexity areas. This is where broad-based automated testing and comprehensive accessibility testing are most effective at managing issue volume and protecting the brand experience.

03

Benchmark your platform

Don’t fly blind. You need to know how your platform’s issue count and criticality rate compare to the 12.2% industry average — and where you sit against it.

The takeaway
Continuous, risk-based testing is no longer just a QA concern — it’s a commercial imperative.
