Doubling conversion rate halves your CAC — for free.
Most CRO agencies A/B test button colours. I audit the whole funnel — search intent, landing message, form friction, checkout drop-off, activation triggers — and run experiments backed by real statistical significance.
CRO is not tricks. It is systematic hypothesis testing.
There is an entire industry of "CRO experts" selling colour changes and pop-up templates. Real conversion rate optimisation is a research-heavy, statistically rigorous discipline. It looks like a scientific method, because it is one: question → hypothesis → test → measure → decide → document.
As a CRO consultant, I start every engagement with a full funnel diagnostic — session replays, heatmaps, form analytics, cart flow analysis, and cohort retention. From that we build a prioritised experimentation backlog. Every test has a written hypothesis, a minimum detectable effect, a sample size calculation, and a stop rule.
The result: 3–5 tests per week, roughly one-third winners, learnings compounding into a playbook your team can run forever. Every winning experiment is compounding leverage on every future ad dollar.
Four layers of the funnel, tested in order
Ad-to-Landing Match
Message continuity from ad creative to landing page hero. If the promise breaks, no downstream test can save the funnel.
Page Experience
Above-fold clarity, social proof placement, objection handling, sticky CTAs, Core Web Vitals. The 90% of visitors who never scroll below the fold.
Form / Cart Friction
Field count, error handling, guest checkout, wallet-first UX, address autofill, RTO risk flags for COD.
Activation & Retention
Post-conversion onboarding, second-order triggers, lifecycle sequences — the CRO most brands never think of.
Engagement deliverables
Twelve weeks. Compounding lift.
Diagnostic
Full funnel research: analytics, session replay, form logs, user interviews. Backlog built.
Foundation
Testing tool live, tracking wired, first three experiments live.
Experimentation
3–5 tests per week, weekly review, backlog refreshed against learnings.
Playbook
Documented what works, testing framework handed over, roadmap for next 90 days.
CRO questions founders ask
How much traffic do I need for CRO?
1,000+ conversions/month unlocks fast A/B testing. Below that we focus on qualitative research + user-tested changes rather than statistical A/B tests.
What testing tool do you recommend?
VWO or Convert for most brands. Optimize is deprecated. If you have engineering bandwidth, GrowthBook or Statsig with server-side experiments.
Will you optimise the whole site or just landing pages?
Whole site. Landing pages, PDPs, checkout, onboarding, lifecycle emails — CRO is a funnel discipline, not a page discipline.
How does CRO relate to performance marketing?
CRO doubles the leverage on every ad dollar. Running paid without CRO is like scaling a leaky bucket.
Do you handle copy, design, and dev of variants?
Yes. Every experiment includes copy, design, dev, QA, and launch. Your team reviews and approves — I own execution.
