First we fixed the conversion. Then we scaled.

The problemA great product with traffic that wouldn't convert — scaling ads on top of that would have burned the budget.
What we didImproved conversion across the store first — then scaled the ads aggressively, with creative tested and refreshed every week.

+93%

returning customer rate

The problem
Plenty of first orders, almost no second ones. Every new customer had to be bought again from scratch.
What we did
Automated email flows after every purchase, retargeting for people who had already bought, and incentives that make a second order the obvious next step.
What happened
Returning customer rate up 93% — growth that no longer depends on ad spend alone.

What we did
Updated the product pages, ran AI-assisted creative that we tested and refreshed weekly, and added email flows that bring people back.
What happened
Revenue up 182%, with repeat purchase carrying a growing share of it.

Inside The Orchestra

Web design · Non-profit
We are so happy with our new website, built and designed by Fully Booked. PJ was fantastic to work with—he struck the perfect balance of taking initiative and moving things forward with minimal support, while also checking in regularly to gather the right details and honor our vision. The end result is a more user-friendly site that's easier for our team to manage on the backend, beautifully simplified in content, and a professional yet playful reflection of our brand. Definitely recommend.

Very satisfied with the collaboration! Pieter-Jan brought my website completely up to date with a clear structure that I can now easily modify and maintain myself. In addition, he ensured a strong Google Ads setup, making us highly visible immediately. Professional, smooth, and effective!
