Confluence Expo Group's flagship Coromandel Industrial Expo had registrations flat at 3,200 with three weeks to go and an 8,500 target still wide open. Here's how a phase-compressed performance marketing blitz turned a plateau into 12,000 registrations by opening day.

The Coromandel Industrial Expo had run eleven successful editions and had a target of 8,500 registrations for its twelfth. The in-house team had been running ads since T-60 — but they were generic "attend our expo" creative with no phase structure, no retargeting sequence, and no urgency mechanics, and the whole budget had been spent evenly instead of paced toward the deadline. By T-21, registrations had plateaued at 3,200: barely a third of target, with sponsors already asking pointed questions about footfall projections and exhibitors quietly comparing notes. Event Director Arvind Balasubramanian called Ziel at T-21 in what he later admitted was near-panic: three weeks to either fill 5,300 more seats or explain to 40 sponsors why attendance would fall short.
Fixed broken pixel events on the registration page, identified where the in-house funnel was leaking, and re-platformed tracking so every rupee spent could be attributed.
Collapsed the momentum and last-chance phases that would normally run over weeks into a tight, daily-paced 19-day plan with its own creative and offers.
Built lookalike audiences off last year's attendee list and launched retargeting for everyone who had visited the site but never registered.
Gave all 40 exhibitors a ready-made promotion kit — creative, copy and tracked links — turning their own networks into a second registration channel overnight.
Broadcast sequences to the existing database and every warm lead, with a visible countdown and price-rise urgency mechanics.
Daily pacing reviews, budget shifted hour by hour to whatever channel was converting, and a last-call push across every warm audience simultaneously.
A short runway isn't a lost cause if it's paced honestly. We told Confluence Expo Group upfront that 8,500 was still reachable but tight — the 12,000 result came from compressing the right phases, not from a miracle channel.
A flat T-21 baseline turned into 141% of the original 8,500 target inside the final 21 days.
Retargeting and exhibitor co-marketing brought cost-per-registration down sharply once the phase plan replaced generic ads.
Every sponsor signed on for next year on the strength of the final attendance numbers.
"I called at T-21 expecting to be told it was too late. Instead they gave us a straight answer — reachable, but tight — and a plan that actually respected the calendar we had left. Watching the registration count climb every single day of that final stretch is something I won't forget."
Registration counts come from the event's ticketing platform, cross-checked daily against ad-platform spend for the same period, tracked from the T-21 baseline of 3,200 stated above. Cost-per-registration by channel is calculated from platform-reported spend divided by attributed registrations. As with every case study we publish, the starting baseline and timeframe are stated plainly.
Tell us your event, date and where registrations stand today — we'll send back a phase-mapped plan with realistic numbers for whatever runway you actually have left. If the timeline's too tight to hit your goal, we'll tell you that too.
