How We Held NYC Attendee Leads Under $3 While Meta CPMs Climbed: 8,344 Leads for Small Business Expo

Small Business Expo is the largest B2B networking and trade show series for small business owners and entrepreneurs in the United States, running roughly 16 to 17 shows a year across major cities. Jumpstart ROI has managed their Meta advertising for years — the ad account history runs back over a decade — driving both sides of every event.

There are two distinct engines in the account:

• Attendee campaigns — city-specific, aimed at small business owners, getting them to claim free tickets to a given city's show

• Exhibitor campaigns — B2B, aimed at larger companies, getting them to book a booth. This is the revenue driver, averaging a 15–18x ROAS on booth sales

This case study focuses on the New York City attendee campaign — one of the largest and most competitive markets on the calendar.

The Challenge

The core challenge repeats every single year, and gets harder each time: CPMs on Meta rise roughly 12% year over year, which pushes the natural floor on cost per lead up with them. The mandate is to beat the previous event year on both lead volume and cost efficiency while the ad auction is actively working against you — and to do it across 16 to 17 separate city launches, each one effectively its own campaign sprint with its own timeline.

NYC concentrates that difficulty. It's a huge, expensive market, so the auction pressure is at its highest there. Holding a low cost per lead in New York while media costs inflate is one of the hardest things to pull off in the account.

What We Did

The NYC result came from a system refined over years of running this event calendar:

1. Relaunched into proven campaign shells. Rather than build from scratch each year, we relaunch the prior year's winning campaign structures where possible, so new creative inherits a lower, more established CPM baseline instead of paying the full "cold" auction price.

2. Ran ruthless creative pruning. Every week we cut any creative running above the CPL threshold and pushed budget into the winners. In NYC that meant quickly concentrating spend behind the single strongest static once the data was clear, instead of spreading it thin across the whole set.

3. Tested aggressively against CPM. Across the account we run dedicated CPM split-test campaigns, lookalike audiences, and retargeting pools built from traffic that didn't convert - specifically to claw CPMs and CPLs back down as the year's costs climb.

4. Scaled the winner to max budget. As NYC held its cost per lead, we scaled it to the full budget rather than capping it, capturing volume while the efficiency was there.

The Results

NYC SPRING 2026 spent $22,950 and generated 8,344 attendee leads at a $2.75 cost per lead, at a $15.10 CPM and a 2.49% CTR.

• Holding NYC under $3 per lead is a strong result on its own

• It beat the prior year's NYC pacing (which sat in the $4-plus range) — roughly a 30% lower cost per lead

• And it did so in a year when CPMs were up double digits

Alongside the attendee engine, the exhibitor campaigns continued delivering their 15–18x business ROAS on booth bookings — the revenue side of the same account.

Key Outcomes

• Held NYC attendee cost per lead under $3 ($2.75) in the account's most expensive market

• Beat the prior year's NYC cost per lead by roughly 30% despite double-digit CPM inflation

• Generated 8,344 attendee leads from a single city launch

• Kept the exhibitor engine delivering a 15–18x ROAS on booth sales

• Repeated the playbook across 16–17 city launches a year, each its own sprint

The Winning Creative

NYC came down to one static. Once the data was clear, we concentrated spend behind the single strongest "New York City" attendee ad — a bold, city-branded free-ticket offer - which drove the overwhelming majority of the campaign's leads at a ~$2.85 per-lead clip while weaker variants were cut. That discipline of backing one proven winner is what kept the cost per lead low as budget scaled.

The Bottom Line

Small Business Expo's calendar is a yearly fight against a rising auction: beat last year on volume and cost, 16–17 times over, while CPMs climb about 12% a year. In NYC — the hardest market of them all — we held cost per lead under $3 and beat the prior year by roughly 30%, on 8,344 leads, while the exhibitor engine kept delivering a 15–18x ROAS. The playbook is the same every launch: relaunch proven shells, prune creative ruthlessly, test against CPM, and scale the winner while the efficiency holds.
