Challenge

As a luxury e-commerce retailer, Cos Bar invests significantly in digital advertising across multiple channels. However, they faced the common challenge of inaccurate attribution—not knowing which ads were truly driving revenue.

Key issues:

• iOS 14.5+ privacy changes — and cookie limitations broke existing tracking

• Missing conversions — tracking solutions couldn't capture all sales

• Incomplete data — made it impossible to optimize ad spend effectively

• No confidence to scale — couldn't track ROI accurately

Strategy

Cos Bar implemented TrueROAS to gain complete visibility into their customer journey and attribution.

How TrueROAS solved it:

• Server-to-server tracking — connected Shopify with all ad platforms, bypassing browser limitations

• AI-powered attribution — analyzes cookies, IP addresses, browser fingerprints, and purchase data

• Real-time data sync — updates every 5 minutes for faster decision-making

• Unified dashboard — single source of truth, eliminating spreadsheets

Solution

Within 4 months of implementing TrueROAS, Cos Bar achieved a 17% increase in ROAS.

Key results:

• 100% order attribution — every sale tracked back to its source

• Budget reallocation — moved spend from underperforming to high-converting campaigns

• Confidence to scale — track every dollar back to revenue

• Better algorithm signals — improved data quality enhanced Facebook and Google optimization
