Which website change actually deserves your next developer slot?
In our experience, most teams already have a long list of website ideas sitting on a backlog: a checkout tweak someone spotted on a competitor's store, a complaint from the sales desk, or a drop-off chart from GA4. Developer time is limited, and building the wrong idea first wastes weeks of budget while the real obstacle stays untouched. - Your team has plenty of opinions on what to change next, with no clear way to rank them by commercial impact. - Analytics shows a big drop-off in the funnel, and you need to know whether it is a real customer barrier or a broken tag. - Mobile visitors browse products or services in high numbers, yet complete far fewer orders or enquiries than desktop users. - Previous design tweaks looked tidier on screen without moving completed orders or qualified enquiries. Agentix runs conversion rate optimisation (CRO) audits for UK eCommerce, B2B and trade businesses. Part of our [website conversion services](/services/website-conversion), we check your measurement first, walk your key buying and enquiry journeys across mobile and desktop, and hand over a ranked, developer-ready action plan.
Why we check the numbers before blaming the page design
In our experience, one of the fastest ways to waste development budget is redesigning a step on the website because of a faulty funnel chart. If GA4 claims that 95% of shoppers abandon the basket, we first verify whether your slide-out cart drawer is actually firing an event when opened. If marketing reports that a quote form has a high completion rate while sales says enquiries are down, we check whether the tag is firing on failed button clicks. Here is an illustrative example with invented round numbers (not a client result) showing how four competing ideas on a team's backlog rank once we check the tracking, customer support logs and live mobile journey across **10,000 monthly sessions**: | Backlog idea from the team | What the surface report claimed | What our audit check found underneath | Commercial priority & action | | -- | -- | -- | -- | | 1. Redesign the product basket drawer | "GA4 shows 0% basket-to-checkout progression" | The slide-out AJAX drawer was working fine for shoppers, but pushed no `add_to_cart` event into Tag Manager | **Do not redesign.** Fix the tracking tag instead of wasting developer time rebuilding a working drawer. | | 2. Show delivery costs & cut
Where website conversion audits uncover the real leaks
In our experience, when we inspect an eCommerce store or a B2B enquiry journey, the biggest commercial gains rarely come from changing button colours. They come from removing the practical obstacles that stop a willing buyer from finishing: | What you see on the site or in reports | What is happening underneath | What it costs your conversion and dev time | | -- | -- | -- | | High basket additions, followed by a sharp drop at checkout | Delivery charges, pallet rules, VAT treatment or stock lead times are hidden until the final payment step | Buyers use your checkout as a price calculator and leave when unexpected costs appear at the end | | Strong mobile traffic, but mobile conversion is less than half of desktop | Sticky headers, chat popups or unformatted number keyboards obscure form fields and error messages on phones | Site managers and mobile shoppers give up mid-form when validation fails without showing which field is wrong | | Visitors use site search heavily, then exit without viewing products | Internal search returns zero results for common trade terms, SKU codes, plurals or slight misspellings | Your highest-intent visitors (who already know the exact item they want)
What you get back from an Agentix CRO audit
You don't get a 90-page generic slideshow of best-practice screenshots. You get a focused decision document built around your commercial journeys: 1. **Measurement truth check.** A clear verdict on which funnel steps in your analytics can be trusted today and which tags need repairing via our [tracking and reporting work](/services/tracking-reporting) before you judge post-change results. 2. **Ranked obstacle and opportunity register.** Every finding is tied to the exact template, device and customer task, ranked by commercial impact and implementation effort so your team knows what to tackle first, second and third. 3. **Developer-ready briefs and success criteria.** For the top priorities, we write clear functional briefs for your developers or designers, specify whether the change should be shipped directly or A/B tested, and define the exact metric that will prove whether it worked.
Frequently asked questions
### Do we need a huge amount of traffic to benefit from a CRO audit? No. Massive traffic volumes are only required if you want to run statistical A/B split tests on minor visual tweaks. A CRO audit combines quantitative funnel data with task inspection, device testing, error checks and customer support questions, so we can spot broken mobile journeys, missing delivery information and form friction on sites of any size. ### Why does a CRO audit check our GA4 and Tag Manager setup first? Because you cannot prioritise website changes around numbers that are wrong. In our experience, apparent funnel drop-offs frequently turn out to be unrecorded AJAX steps, cross-domain splits at payment gateways, or form triggers firing on failed clicks. Checking the measurement first stops your developers from trying to fix a design problem that is actually a tracking gap. ### Will you implement the website changes, or hand them to our developers? We can work either way depending on your platform and team setup. Where you have an internal development team or platform agency, we write clear, prioritized specifications for them and verify the release once it goes live. Where you want us to handle the
