Track when users click "[CTA label]" on [/pages/your-page] — fire to both GA4 and Meta Ads.
Want more control? See the expanded prompt ›
Fire a GA4 event called `start_quiz_clicked` when a user clicks the 'Start the quiz' button on /pages/find-your-match. Also fire to Meta Ads as a `Lead` event. Include the page URL in the event properties.
- Fires custom events on any click, scroll, or interaction.
- Hits GA4, Meta Pixel, TikTok Pixel — any platform you're connected to.
- Event properties (page URL, product, value) are configurable.
- Auditable — Fudge logs every fired event for debug.
What you're trying to do
Marketing platforms get smarter the more events you feed them. Off-the-shelf event tracking covers pageviews and add-to-cart, but the events that matter — quiz starts, video plays, popup signups, scroll-to-section — usually need custom wiring. Fudge does that wiring in seconds, for any element.
Things to watch out for
- Event consistency — Fudge uses GA4 conventions (snake_case names).
- Privacy — Fudge handles this: events respect cookie consent.
- Platform parity — Fudge handles this: same event can fire to multiple platforms simultaneously.
- Debug mode — Fudge can enable GA4 debug to verify in real time.
How Fudge does it
Fudge duplicates your live theme into a draft, makes the targeted edit (Liquid logic, JS event, conditional rendering) your prompt requires, and tests it on the draft preview. Everything starts in draft — review the diff, verify the behavior, and publish when you're ready. Your live store stays untouched.
Why custom event tracking matters for paid traffic
Default GA4 and Meta Pixel events miss the things you actually care about — quiz starts, video plays, cart abandonment moments, scroll depth. Custom events fill the gap, giving you proper attribution and the data you need to optimize ad creative.
When this is worth doing
Set up custom events for any high-leverage interaction — quiz starts, video plays, custom CTAs. Especially worth doing before scaling paid traffic, since the attribution will inform the spend.
What makes a great implementation
- Specific events for high-leverage actions — not just clicks.
- Fired to GA4 + Meta Ads — both platforms need the data.
- Page URL in event properties — for cross-page attribution.
- Privacy-aware — respects cookie consent. Fudge handles this automatically.
- Event names that match Meta’s standard event vocabulary — Lead, AddToCart, Purchase. Lets Meta optimize better.
Common mistakes to avoid
The biggest mistake is over-eventing. Too many custom events make the data noisy and harder to analyze. Pick the 5–10 highest-value actions.
The second mistake is missing the privacy layer. Tracking without consent triggers GDPR/CCPA issues.
