Martial Arts Group (MAG), based in The Hague, supports federations, gyms, businesses and martial artists with marketing, management and a network that brings the sport together. MAG runs platforms for judo, BJJ, wrestling, boxing, kickboxing, sambo, kung fu and eskrima: from Judo.nl and BJJ.nl to Worstelen.nl, Kickboks.school and Kickboksen voor Kinderen. TRON Group is MAG's technology partner. We build, host and manage eleven martial arts platforms plus martialartsgroup.com itself, and MAG says so in its own logo: powered by TRON Group. Below you can read how the platforms are set up, why every sport keeps its own brand, and what that delivers for the athletes and gyms who use them.
Starting point
The challenge
Anyone who wants to start judo, boxing or BJJ searches on their phone for a club nearby, often in the evening and often for a child. That visitor wants to know within seconds where the nearest club is, when classes run and how to book a trial class. MAG had a series of separate WordPress sites for this, built up sport by sport, with years of pages that already ranked well in Google. The brief: make every platform faster, more secure and easier to find, without losing that hard-won visibility and without any sport losing its own identity. And all of that for a growing number of sports, so a new platform can be added quickly.

How we tackled it
Our approach
One shared platform, a distinct brand for every sport
Each platform has its own name, visual identity and tone: Judo.nl feels different from Kickboksen voor Vrouwen. Technically, they share the same build. That means improvements to speed, search visibility or security roll out across every platform at once, and a new sport goes live faster.
Keeping every old page, and the rankings that came with it
During the move away from WordPress, every existing URL was kept or given a clean redirect. That way each platform carries over the rankings it had built up in Google. A check in the build process blocks a new release as soon as a page is missing a title, description, canonical or structured data.
A page for every town
People search for 'judo in' or 'boxing in' followed by where they live. That is why a platform like Kickboks.school has a page for every town in the Netherlands, listing nearby clubs with their address and class times. Across all the platforms, that adds up to thousands of pages. For AI search engines, each platform also publishes an llms.txt file summarising the site.
Clubs and class times always up to date
On nine of the eleven platforms, clubs, addresses and class times come from a single central source and are updated automatically every night. If a timetable changes, it is correct on the platform the next morning. Where a club offers it, you can book a trial class directly on the site.
Hosting and management by one team
The platforms run as pre-built pages on Cloudflare's global network. That makes them fast on any phone and gives attackers very little to work with: there is no admin panel or database reachable from the internet. TRON manages the hosting, the updates and the ongoing development.
The big picture
The solution
MAG works with one technology partner for the whole network. Eleven martial arts platforms, from Judo.nl to Eskrima.nl, and the hub martialartsgroup.com run on the same technology, which TRON Group builds, hosts and manages. Every sport keeps its own brand, colours and tone, so a parent looking for kickboxing classes for their child lands on a different site from a BJJ athlete looking up a new technique. Under the surface they share the same fast, secure foundation, the same search visibility checks and, on most platforms, the same nightly update of clubs and class times. When TRON improves that foundation, every platform benefits at once.
What it delivers
The results
- Martial arts platforms live, plus martialartsgroup.com
- 11
- Pages, including one for every town, for people searching locally
- Thousands
- Kept or cleanly redirected during the move away from WordPress
- Every URL
- Clubs and class times updated, on nine of the eleven platforms
- Every night
The result is a network that can be managed as one whole, yet stays recognisable sport by sport. Someone searching on Google finds a club in their town, sees the class times and books a trial class, on a page that loads instantly on their phone. For MAG, it means one technology partner for every platform, ready to add a new sport quickly. That is why it says so in MAG's logo: powered by TRON Group.
