Case studies

Atari coordinated a first-party tracking implementation with Bily in early 2025. The setup was confirmed working on 2 April 2025, and current Bily product records show activity in July 2026.

Maison Fleurs de Bach has worked with Bily across multiple implementation milestones, with current product activity verified in July 2026.

In a matched Meta test using the same ad sets and ads, ecommerce operator Andrew Faris reported stronger signal quality with Bily and calculated an 11% lift in the delayed-attribution ROAS comparison.

After Bily restored more of Flowrette's conversion signal, the brand recorded 31% lower CPC, 18% lower CPM, and 9% lower CAC over 15 days.

Diamants de Paris restored 65% more event data to Meta, then recorded 22% lower CPC and 14% lower CAC over the first 15 days.

A side-by-side pixel test recorded 37% more PageView data and three additional event types with Bily; the unchanged prospecting campaign later showed 33% lower CAC.

After improving Meta signal coverage with Bily, Pohesia doubled ad spend while recording 7% lower CPC and 10% lower CAC over two weeks.

Over three months, Osée sent more than 50% additional event data to Meta, tripled ad spend, and reduced CAC by approximately 45%.

After testing Bily against an existing Pixel and CAPI setup, MyVariations recorded 30% more Meta-attributed sales and 25% lower in-platform CPA.

In a six-day Meta comparison with spend within 1.4%, a confidential e-commerce brand’s Bily-connected campaign recorded 55% higher in-platform ROAS.
