The Problem

Walk through the Compare the Market car insurance funnel and you'd think you were looking at a product that had never been challenged. The page works — users convert, quotes start, results load. But beneath the surface it carries assumptions that compound quietly into real lost revenue.

A CTA that asks new visitors to choose between two equally weighted actions before they've committed to anything. A savings claim buried in the sub-hero where scan-readers never reach it. An app install banner firing at the top of every session, on users who've never heard of the Meerkat app. A rewards block that lists perks but never quantifies them.

None of these were mistakes. They were reasonable decisions that were never tested. CTM sends millions of users into this funnel every month — a fraction-of-a-percent improvement is worth millions in incremental revenue. The funnel didn't need a redesign. It needed a structured challenge.

What I Did

I treated the CTM car insurance funnel as a product to be optimised, not a page to be redesigned.

Rather than jumping to solutions, I built an evidence-based test backlog using a three-phase process:

  • Conducted an end-to-end funnel walk across desktop, mobile, and tablet — cataloguing every friction point, trust gap, and missed intent signal from landing through quote completion

  • Developed 12 A/B test hypotheses across three areas: car insurance funnel mechanics, cross-sell and upsell, and mobile experience

  • Scored each test on impact, confidence, and effort using RICE, then prioritised into P1, P2, and P3 tiers

  • Built hi-fidelity prototypes for all six P1 tests using real CTM design tokens extracted from the live Figma file (node 154:11518) and live site CSS

    P1 Test Results

Prototype Standards

Every prototype was built to the same brief: close enough to the live product that stakeholders evaluate the UX decision, not the visual fidelity.

  • Real CTM design tokens — cobalt (#2843d0), border radii, type scale — extracted from the live site and Figma node 154:11518

  • White two-column hero layout matching the actual car insurance page architecture

  • Active nav tabs, trust bar, pricing anchor, and result cards from real component patterns

  • Control and variant rendered side by side with hypothesis annotation and primary metric

Results

Projected uplifts based on industry benchmarks for equivalent CRO interventions. Not measured post-launch results — these are estimates to inform business case and prioritisation.


TEST

CHANGE

ESTIMATED UPLIFT

T01 — Single CTA

Remove choice friction

+5–8% quote starts

T02 — CTA Copy

Motivation framing

+3–7% CTR

T04 — App Banner

Remove early exit on mobile

+4–10% mobile quote starts

T05 — Age Pricing

Personalised anchor near CTA

+6–12% quote starts

T06 — Rewards £

Quantify annual value

+8–15% XS from car page

T07 — Post-quote XS

Peak-intent intercept

+20–35% XS from results


If even three of the six tests beat control, the compound effect on quote volume — at CTM's traffic scale — represents a material revenue opportunity in the tens of millions annually.

What I Learned

CRO work is fundamentally a research discipline. Every element on a high-traffic page is a hypothesis about what users need at that moment — and the ones that have never been tested are usually the ones that feel most obvious.

The most useful question wasn't "what should we change?" It was: what does this UI assume the user already believes? The dual CTA assumes visitors are in two equally distinct modes. The savings claim assumes the headline number motivates equally across age groups. The app banner assumes users have context for the Meerkat app before they've started a quote.

Working from real design tokens also reinforced something I care about: a prototype that looks different from the live product invites the wrong conversation.

My Role

  • End-to-end funnel audit across desktop, mobile, and tablet

  • 12-test hypothesis backlog with RICE prioritisation

  • Hi-fidelity prototypes for all six P1 tests — control and variant

  • Design system extraction from live Figma file and live site CSS

  • Test specifications with primary/secondary metrics and engineering implementation notes
