CRO Case Study Rockstar Nails

The starting point

Shop type & industry

Beauty & Cosmetics

The problem

A growing nail-cosmetics shop with loyal repeat customers and a strong mobile share. The problem was not demand, but unnecessary hurdles on the way to the checkout: too many steps, too much distraction, too little clarity on mobile.

Hypotheses & the tested variant

From the starting point we derived the following hypotheses — each was tested as its own variant against the existing version, never rolled out blindly:

Targeted checkout fixes instead of a rebuild: identify purchase barriers and remove them one by one. That included simplifying the order path, clearer calls to action, and resolving uncertainty immediately before purchase, prioritised by expected leverage, not by effort.

Measurement & test duration

The changes were measured as A/B tests against the starting version, with particular focus on mobile use. What counted was the actual revenue effect, not click counts or gut feeling.

Observation period: The first 30 days

Result

A clearly double-digit revenue increase over the baseline within the first 30 days, achieved purely by removing friction in the existing shop, with no additional ad budget.

Business significance

A clearly double-digit revenue increase within the first 30 days — with no additional ad budget. For the shop that means more revenue at unchanged marketing spend.

Limitations

This case study is an anonymised account: for confidentiality reasons we do not publish client-specific figures. Individual results are not directly transferable — the test context decides what applies: the industry and size of your shop shape the outcome. We are happy to walk you through concrete metrics and our approach in a conversation.
