21 Aug Is a Facebook Event Custom Audience Worth Using?
Generally not. Getting people to click “interested” or “going” on a Facebook or Instagram event feels like progress — it’s a number going up, engagement happening. But that click is one of the easiest, lowest-commitment actions on the entire platform, and it rarely translates into someone actually showing up or buying a ticket.
Why event engagement is a weak signal
Clicking “interested” takes no real thought. Someone sees an appealing poster, or notices a friend has RSVP’d, and taps the button without much consideration. Plenty of people who click don’t remember doing it a day later, let alone follow through on attending. It’s a casual, low-friction action — closer to a passive like than a genuine expression of buying intent.
Building a retargeting audience out of that engagement means building on a foundation that doesn’t reliably predict what you actually care about: whether someone shows up, registers, or pays.
The pattern this critique is aimed at
The common approach is to run ads driving people to engage with an event first, then retarget those engagers toward the real goal — a ticket purchase through Eventbrite or whichever platform is being used. This treats event engagement as a springboard: get the easy click first, then work toward the real conversion afterward.
That extra step isn’t necessary, and it adds a weak-intent layer between your ad and the actual sale. If the ticketing platform is already set up and ready to take a payment, there’s little reason to route people through an “interested” click first rather than sending them straight there.
Skip the springboard
Send people directly to the real conversion action — the ticket page, the registration form, whatever the actual next step is. This is more direct, and it means whatever custom audience you do build afterward is based on people who took a genuinely meaningful action, not a casual button click. It’s the same underlying idea covered in why video engagement makes a weak retargeting audience — the shallower the action, the less it tells you about real intent, regardless of which specific low-commitment action it is.
A quick self-check
- Am I asking people to take an easy, low-commitment action before the real one, when I could send them straight to it?
- Is my ticketing or registration platform already capable of receiving traffic directly, without needing an event-engagement step first?
- If I already have an event engagement audience, is it actually converting, or just accumulating clicks that don’t go anywhere?

Frequently Asked Questions
Is a Facebook or Instagram event custom audience useful for retargeting? Generally not. Clicking “interested” or “going” on an event is one of the easiest, lowest-commitment actions available on the platform. It doesn’t reliably indicate someone will follow through to an actual ticket purchase or registration, which makes it a weak foundation for a custom audience.
Why isn’t clicking “interested” or “going” on an event a strong intent signal? It’s a single button click that takes almost no thought or commitment. People click it casually — because a poster looked appealing, or a friend was going — often without any real intention of attending or buying a ticket, and many don’t even remember doing it afterward.
Should I run ads to get people to engage with my event before asking them to buy a ticket? No. Using event engagement as a springboard before asking for the real action adds an unnecessary low-intent step. It’s more direct, and generally more effective, to send people straight to the actual conversion action — a ticket purchase page or registration form — rather than routing them through an event engagement click first.
What should I do instead of building an event engagement custom audience? Drive traffic directly to the real conversion point, whatever platform you’re using for it — a ticketing page, a registration form, or a checkout. Build custom audiences from that deeper action instead, since it reflects genuine intent rather than a casual click.
