BLACKROLL Case Study to Unlock 7-Figure Growth

sleep products had quietly grown to 60% of their sales

but their site still spoke only to athletes.

Two mindsets.

One generic experience.

And conversion rates were slipping especially on mobile, where 80% of traffic landed.

As their CRO agency, we re-engineered the entire testing strategy.

Here’s what we did:

- Split experimentation into two funnels: active vs. passive recovery

- Built persona-specific testing roadmaps

- Mined reviews & surveys to decode buyer psychology

- Watched 40+ hours of session recordings

- Launched mobile-first A/B tests across key pages

- QA’d and shipped every experiment clean

The results:

+34% bottom-line revenue growth

+€28,636/month average uplift per winning test

A fully integrated CRO engine, aligned with Blackroll’s OKRs
