Methodology

Research first.
Then experiments.
Then compounding wins.

The PXL framework used by conversion specialists worldwide. Every plan we run follows the same five steps. Context is king. All five combined tell us where to optimise and what to optimise for.

5 steps · From research to testing

How every engagement runs.

Each tier of our CRO Plans follows this same flow. The depth scales with the plan, the structure does not.

STEP 01

Research

Understand audience motivations and anxieties before touching the site. Heuristic UX audits, competitive analysis, qualitative interviews where applicable.

STEP 02

Gathering data

Combine GA4 funnels, heatmaps, session recordings and sentiment analysis to find every leak. The full quantitative + qualitative picture.

STEP 03

Hypothesis

Turn the strongest signal into a clear, measurable hypothesis with a business case. Each one ranked via PXL prioritisation before it enters the queue.

STEP 04

User testing

Validate the variation in a fast, controlled environment before shipping to production. 5-second tests, preference tests, qualitative interviews.

STEP 05

A/B testing

Run structured experiments with enough power to declare a winner with confidence. Pre-registered hypothesis, primary + guardrail metrics, MDE calculated upfront.

Our methodology stands on the shoulders of CXL’s PXL prioritisation, MECLabs’ conversion formula, and twenty years of academic and applied research.
