The core business goal is to acquire high-quality leads/sales, lower customer acquisition costs (CAC), and maximize Return on Ad Spend (ROAS) across paid channels.

Tracking & Conversion Infrastructure: Verify and optimize tracking pixels, Conversion API (CAPI), and event tracking for precise attribution.
Optimization & A/B Testing: Continuously test ad creatives, copy variants, landing page flows, and bidding strategies to reduce CPC and CPA.
Budget Management & Reporting: Manage and scale daily/monthly ad spend efficiently; provide weekly KPI dashboards covering CTR, CPC, CPL, CPA, and ROAS with actionable optimization notes.
