Scaled Meta spend from $3k to $14k/mo while holding 3.9× ROAS.

The challenge

ArcVest was stuck at $3k/mo Meta spend with inconsistent ROAS between 1.8× and 3×. Every time they scaled budget, performance degraded. The problem was dirty conversion data feeding the algorithm wrong signals.

What we did

• CAPI implementation to fix conversion signal quality
• Rebuilt campaign structure from scratch — fewer campaigns, cleaner data
• Introduced Purchase-optimized campaigns fed by server-side events
• Creative testing framework with weekly iteration cycles
• Gradual budget scaling protocol — 20% per week with ROAS gates

Results

• Stable 3.9× ROAS maintained from $3k through $14k/mo spend
• Peak month hit 4.6× ROAS at $16k spend
• Removed 8 underperforming ad sets that were cannibalizing budget
• Creative refresh every 3 weeks preventing fatigue-driven ROAS drops
