Project Overview

With Meta ad lead acquisition costs (CPL) reaching $150+, severely impacting profitability, we set out to maximize ad efficiency and secure "high-quality leads" that convert into actual consultations. Beyond simply swapping creatives, we optimized the entire funnel through conversion path A/B testing and technical tracking reinforcement.

The Challenge

• Excessive Lead Costs: CPL at $150+ per lead, making revenue conversion efficiency extremely low relative to ad spend
• High Lead Absence Rate: 46% of acquired leads were unreachable, wasting sales team resources with only 20.7% consultation success rate
• Data Loss Issues: Low-barrier instant forms attracted fake leads, while browser cookie restrictions caused data loss, making performance measurement unreliable

Strategy / Solution

1. Conversion Path A/B Testing & Landing Page Optimization: Enhanced Meta instant form tracking, built custom landing pages, and tested 40+ video/image creatives to find the optimal combination driving high-intent engagement.
2. Technical Tracking Enhancement (CAPI & Webhook): Integrated server-side API (CAPI) to prevent data loss and developed webhooks for real-time CRM data synchronization.
3. Sales Data Feedback Loop: Analyzed consultation success and absence rates to refine campaigns toward audiences with genuine consultation potential, not just clicks.

"A marketing engineer's role doesn't end at lowering ad costs — it extends to ensuring data integrity through technology and connecting it to real sales performance."

Execution

• Tech Stack: Meta Pixel/CAPI, GTM, HTML/CSS/JS, PHP, Webhook
• Key Activities: Meta Business verification and app creation, lead form refinement, landing page speed optimization and funnel tracking code implementation
