Zombie Fest 9.
Rebuilt from the tracking up.
Cambridge Junction. 1,500 capacity. October 2026. A full ad account rebuild, tracking repair and a Skiddle Conversions API integration, planned against two years of real buying data.
The brief.
Zombie Fest is an established event with a loyal crowd. The ask was simple: sell the room, and know what each ticket cost to sell.
Before any money went into ads, we needed to know two things. Was the tracking telling the truth? And when does this audience actually buy?
What we found.
Pixel set-up
The pixel structure didn’t give the event a clean, dedicated source of buyer data.
Conversions API
Server-side purchase reporting wasn’t in place, so purchases blocked in the browser were going unreported.
Purchase events
The events the campaigns relied on couldn’t be trusted as real ticket purchases.
Campaign objectives
Campaigns weren’t set to optimise for purchases that could be properly tracked.
What we fixed.
We rebuilt the ad account structure, cleaned up the pixel and dataset set-up, and connected Skiddle’s Conversions API integration so purchases reach Meta server-side as well as through the browser, de-duplicated by order ID.
Then we set the campaigns to optimise for Purchase, the one result that actually fills the room. Read how that works in our Skiddle promoter marketing guide.
Two years of exports. One clear shape.
We modelled the curve from the ZF7 and ZF8 ticketing exports. Both sold far more in the final week than the roughly 20% platform average.

Client ticketing data, ZF7–ZF8 (approx.)Money where the buying is.
The plan is back-weighted. A lean spend at announcement and on-sale captures existing fans and builds retargeting pools. The middle stays warm without forcing it. The bulk of the budget lands in the final month, with meaningful spend held back for the final 72 hours, when more than a quarter of tickets have historically sold.
Budget held in reserve for the window that decides the night.
