Meta cost per purchase down 25% for a New Zealand kids’ clothing brand
How numero® rebuilt Meta advertising for Radicool Kids, a New Zealand designed and owned kids’ label, and brought in more orders for less spend.
The client
New Zealand designed and owned, born in Dunedin
Radicool Kids is a New Zealand designed and owned kids’ clothing brand, born in Dunedin. It started with Radicool Dude for boys, added Kissed by Radicool for girls in 2014 and Rad Tribe unisex basics in 2017, all drawing on surf, skate and street culture.
The challenge
Three ranges, four seasons and a full promotions calendar
Radicool Kids launches new collections every season and runs a sale or promotion most months. Meta had to keep the right range and the right offer in front of parents, and turn every dollar into orders at a cost that pays back.
Three ranges, one account
Boys’, girls’ and unisex ranges sell to different shoppers. Each needed its own campaign, not one catch-all.
New stock every season
Autumn, winter, spring and summer collections each need fresh catalogues, images and copy on time.
Offers that change weekly
Mystery Bags, flash sales, mid-year and clear-out sales all need ads live the day they start.
What we did
Rebuild, run every offer, then report on what sells
Meta rebuilt around the ranges, then tuned month by month against Shopify orders.
