The challenge

For a kids' class, it's the parent who signs up.

Kiss Fighting Academy is coach Barni's Muay Thai gym in Budapest's sixth district, on Szív utca — the coach competes on the national team himself. The goal: fill the 10–15 age group's class from Facebook ads, with a free first session as the offer.

That took two things. A landing page that convinces the parent — because the parent clicks the ad, makes the decision and registers the kid in the booking system. And tracking that tells the truth about ad spend: a conversion counts when the application actually arrives — not when someone pressed a button.

The system — 01 · Site

Storefront and front desk in one

kissfightingacademy.com is a static Vite 6 build on Coolify/Hetzner hosting, fully bilingual — Hungarian and English. Beyond the home page there is a dedicated room-rental page, and the legal pages are in order.

For members, the embedded Motibro system is the front desk: class schedule, booking and pass management in one place. The website brings people in, Motibro takes it from there.

The system — 02 · Landing

A landing page that speaks to the parent

The 10–15 age group's Muay Thai class got its own landing page, built specifically as a Facebook-ad destination. The offer is simple and strong: the first class is free. The messaging wasn't guessed — it followed a documented research pass over other gyms' ads.

Trust rests on real signals: 45 Google reviews at a 5-star average, from parents and students — and coach Barni, a national-team competitor himself.

The system — 03 · The application's path

What happens after the click?

This is the core of the system: from the Facebook click to the parent's inbox every step is automatic — even the landing page's time slots refresh themselves.

  1. META ADS

    A click on the ad

    The Facebook ad doesn't point at the homepage but at the dedicated kids' Muay Thai landing page — its messaging drawn from the competitor research, not gut feeling.

    ✓ landing loaded — source: facebook ad

  2. LANDING

    Slots that never expire

    The page generates trial-session slots at runtime: it always shows the next Tuesday and Thursday 16:30 classes. No stale dates, no manual updates.

    ✓ slots generated — next Tue / Thu 16:30

  3. FORMSPARK

    Sign-up, minus the spam

    The form is guarded by a honeypot and a time trap: bots fill the invisible field or submit too fast — only a real application travels on.

    ✓ submission valid — honeypot empty, time trap OK

  4. N8N

    The webhook takes over

    The submitted application arrives at n8n over a webhook and kicks off the onboarding workflow — no human hand involved.

    ✓ webhook received — onboarding started

  5. PARENT EMAIL

    The parent gets everything

    An automated bilingual email goes to the parent with step-by-step registration for the Motibro booking system — by the time the first class comes around, the kid arrives already registered.

    ✓ onboarding email sent — HU/EN

FIG. 02.C — THE APPLICATION'S PATH, STATION BY STATION

The system — 04 · Tracking

Measured twice, counted once

Tracking runs on two channels. The Meta Pixel runs in the browser; on the server, a self-hosted Node.js microservice (kfa-capi.sovi.hu) sends the same events to the Meta Conversions API. Both channels carry a shared event_id, so Meta deduplicates — the conversion still shows up when something swallows the browser-side hit, but it never counts twice.

The Lead event fires on the actual form submit, not on the CTA click — so the ad algorithm optimizes for real applications, not button presses. And PostHog analytics loads only after cookie consent.

From the click to the first class, no manual work.
