Conversion rate optimisation that compounds your paid media returns
You do not have a traffic problem. You have a conversion problem. Most brands pour budget into acquiring clicks and then lose half of them to poorly structured pages, confusing forms, and friction that nobody has bothered to measure. CRO is the multiplier that makes every pound you spend on ads work harder. We approach it as a structured testing discipline - not a redesign project, not a heatmap exercise, but a repeatable system for improving the rate at which visitors become customers.
Who this is for
Built for businesses that need results, not reports.
- 01Brands with strong traffic but conversion rates below industry benchmarks
- 02Ecommerce businesses with high cart abandonment and no structured testing programme
- 03Lead generation companies getting form visits but not form completions
- 04Marketing teams that have never run a proper A/B test with statistical rigour
Problems we solve
If any of this sounds familiar, we should talk.
- 01Your conversion rate has been flat for six months but nobody has tested anything
- 02You redesigned your website and conversions went down - but you do not know why
- 03Your checkout or form has multiple steps and you have no data on where people drop off
- 04Previous CRO work amounted to changing button colours and calling it optimisation
- 05You are getting traffic from paid media but the cost per acquisition keeps rising
- 06Mobile conversion rates are significantly worse than desktop but nothing has been done about it
Our approach
How we run CRO that actually moves revenue
Conversion audit
We map the full conversion funnel - from first click to final action - and identify the highest-impact drop-off points. This combines analytics data, session recordings, form analytics, and user behaviour analysis to build a complete picture of where and why visitors fail to convert.
Hypothesis development
Every test starts with a structured hypothesis: what we are changing, why we believe it will improve conversion, and what metric will determine success. No guessing. No opinion-led changes. Each hypothesis is prioritised by potential impact, confidence level, and implementation effort.
Experiment execution
We run A/B or multivariate tests with proper sample size calculations and statistical significance thresholds. Tests run until we have confidence in the result - not until someone gets impatient. We measure against downstream metrics: revenue per visitor, cost per acquisition, or lead quality.
Implementation and iteration
Winning variants are implemented permanently. Losing variants generate documented learnings that inform the next round. Over time, this builds an institutional knowledge base of what works for your specific audience, product, and funnel.

What makes Avium different
Not another agency pitch.
- 01We measure CRO against revenue and acquisition cost, not conversion rate in isolation - a higher rate means nothing if lead quality drops
- 02Every experiment has a pre-registered hypothesis, sample size calculation, and significance threshold
- 03We work across the full funnel - ads, landing pages, forms, checkout, and post-conversion - not just the page level
- 04CRO is integrated with our paid media management, so improvements are immediately reflected in campaign performance
- 05Our testing framework has contributed to 31% lower CPL and 4.8x ROAS across the portfolio
Frequently asked questions
How is CRO different from just redesigning my website?
A redesign changes everything at once based on opinion. CRO changes specific elements based on evidence. Redesigns often reduce conversion rates because they introduce untested assumptions. CRO improves conversion rates because every change is measured against a control.
How much traffic do I need for CRO to work?
Meaningful A/B testing requires sufficient conversion volume - typically a minimum of 200 conversions per variant per month. If your traffic is lower than that, we focus on high-impact qualitative changes and pre/post measurement rather than split testing.
What tools do you use for CRO?
We use a combination of analytics platforms, session recording tools, A/B testing software, and form analytics. The specific tools depend on your tech stack. What matters is the methodology - tools are interchangeable, process is not.
How quickly will CRO improve my results?
Individual tests typically run for two to four weeks depending on traffic volume. Most clients see their first meaningful wins within 60 days. The compounding effect - where each improvement makes the next test more impactful - builds over three to six months.
Can you do CRO without managing our ads?
Yes, though the impact is greater when CRO and paid media management are integrated. We offer standalone CRO engagements that work alongside your existing media buying team or agency.
What does a CRO engagement cost?
Pricing depends on the scope - traffic volume, number of conversion points, and testing velocity. We scope every engagement individually based on your specific situation and the opportunities identified in the initial audit.
Do you only optimise landing pages?
No. We optimise across the full conversion funnel - landing pages, product pages, checkout flows, lead forms, email sequences, and any other touchpoint that affects whether a visitor becomes a customer. The biggest gains are often in places people are not looking.
What if a test loses?
Losing tests are as valuable as winning tests - they tell you what does not work for your audience. Every result, positive or negative, is documented and feeds into the next round of hypothesis development. The system gets smarter over time.
