Data Audit
We analyse your GA4 funnels, heatmaps, and session recordings to identify the highest-impact drop-off points — the specific moments where visitors abandon instead of converting.

CRO That Turns
More Visitors Into Revenue

What We Do
CRO Built on Data, Not Opinions
Most websites convert 1–3% of their visitors. The other 97–99% leave without taking action — and most businesses respond by spending more on ads to drive more traffic into a leaky funnel. CRO flips this equation: fix the funnel first, then scale traffic into a system that actually converts.
Lumo's CRO process starts with a comprehensive data audit. We analyse your GA4 funnel data to identify exactly where visitors drop off, use heatmaps and session recordings to understand why, and conduct expert UX reviews to spot barriers that data alone doesn't reveal. Every hypothesis we test is grounded in evidence, not gut instinct.
Our A/B testing framework runs structured experiments across landing pages, CTAs, headlines, forms, pricing pages, and checkout flows. We prioritise tests by expected revenue impact — high-traffic pages with meaningful drop-off rates come first. Every test runs to statistical significance before conclusions are drawn.
CRO is not a one-time project — it's a continuous improvement system. Lumo maintains a rolling test backlog, so the moment one test concludes, the next is already queued. Over time, these compounding improvements create a website that converts dramatically better than it did 6 or 12 months ago.

How It Works
Our CRO Process
02
Hypothesise + Prioritise
We develop evidence-based hypotheses for each drop-off point and prioritise them by expected revenue impact — focusing effort where conversion gains matter most.
03
Test + Measure
We build A/B test variants, implement them via testing software, and run experiments to statistical significance before drawing conclusions — no premature decisions.
04
Iterate + Compound
Winning variants are implemented permanently. Losing tests inform new hypotheses. The cycle continues monthly, compounding conversion gains over time.
Common Questions
CRO FAQ
What does CRO include?
Lumo's CRO service covers heatmap and session recording analysis, funnel drop-off identification, landing page A/B testing, copywriting optimisation, form optimisation, page speed improvements, and mobile UX fixes. We prioritise tests by expected revenue impact, not complexity.
How long does CRO take to show results?
Initial quick wins — form simplification, CTA copy changes, page speed fixes — often show measurable uplift within 2–4 weeks. Full A/B test cycles typically run 3–6 weeks to reach statistical significance. Most clients see compounding conversion improvements over 3–6 months as multiple tests are completed.
What tools does Lumo use for CRO?
We use Hotjar or Microsoft Clarity for heatmaps and session recordings, Google Optimize or VWO for A/B testing, GA4 for funnel analysis, and Google PageSpeed Insights + Core Web Vitals data for performance diagnostics. Tool selection is adapted to your existing stack.
How much traffic do I need for CRO to work?
Meaningful A/B tests require at least 500–1,000 unique visitors per variant per week to reach statistical significance in a reasonable timeframe. For lower-traffic sites, we focus on qualitative methods — session recordings, user surveys, expert UX review — to generate high-confidence hypotheses without waiting for test significance.
Does CRO work for both e-commerce and lead generation?
Absolutely. For e-commerce, we optimise product pages, cart flow, checkout, and category pages to increase transaction rate and average order value. For lead generation, we optimise landing pages, contact forms, and lead magnets to increase form completion rates and lead quality simultaneously.
