"Manual media buying was holding us back— with Birch we never miss an opportunity to scale."
Valentinas Ubartas
Head of Growth, ColonBroom
Challenge
- Manual Optimization Bottlenecks: Budgets and underperforming ads were adjusted manually, typically only once or twice per day, limiting how fast campaigns could scale.
- Time- Consuming Creative Testing: Hundreds of creatives were tested manually in large batches, requiring constant monitoring to pause losers and identify winners.
- Missed Scaling Signals: Without real-time alerts, strong creatives could be overlooked, especially outside working hours.
- Limited Media Buying Capacity: One media buyer could realistically manage only one large account due to the volume of daily optimizations required.
Solution
Scaling Business as Usual Campaigns
- Campaign-Level Budget Scaling: Budgets are increased automatically multiple times per day based on performance signals. Scaling decisions rely on custom performance data pushed hourly into Google Sheets, which integrates with Birch, ensuring optimizations are driven by internal business metrics, not just platform-reported data.
- Campaign & Ad Set Stop-Loss: Daily performance-based rules automatically pause underperforming campaigns and ad sets, protecting efficiency while enabling aggressive scaling.
Creative Testing Automation
- Winner Alerts via Slack: When a creative reaches predefined performance benchmarks, Birch triggers real-time Slack notificationsI, ensuring winners are never missed and can be scaled immediately.
- Underperformers Paused on Ad & Ad Set Level: Spend thresholds dynamically adjust based on the number of conversions already generated, allowing fair testing while cutting losers quickly.
ColonBroom (Kilo): Pause Creative Test Losers
This rule continuously monitors new creative test ads over their first week and automatically pauses underperforming creatives. Every hour, it evaluates each ad against a dynamic performance ladder based on spend and conversions, ensuring only ads showing meaningful results continue to run, while low performers are stopped before wasting budget
Results:
- 88% Increase in Daily Spend with Faster Creative Scaling: within 2 months of implementing the first scaling rule, average daily spend increased by 88%. Real-time alerts and automated decisions ensured winning creatives were identified and scaled immediately, accelerating growth.
- Scaled Aggressively While Maintaining Strong ROAS: Bïrch enabled the team to scale campaigns fast while maintaining healthy ROAS.
- 2x Media Buying Capacity: media buyers can now manage 2 large accounts simultaneously—doubling capacity without increasing headcount.
