Driving 50%+ CPA Reduction with Smart Supply and PubMatic

How supply-side intelligence and premium supply transformed performance for a leading insurance brand.

Overview

An insurance brand needed to improve performance and lower CPA, but their DSP-led strategy wasn’t delivering. Despite high impression volume, conversions were inefficient and traffic quality was inconsistent.

Smart Supply partnered with PubMatic to shift the focus to supply-side deals. By activating premium deal IDs through PubMatic’s Connect platform, the campaign filtered out low-performing inventory, prioritized affinity-aligned audiences, and applied real-time optimizations based on outcomes—not proxies.

The solution

Programmatic performance now relies on intelligence applied directly at the source of supply. To deliver consistent, measurable results, you need partners who can execute pre-bid logic.

Filters inventory before the bid—ensuring cleaner, more intent-rich impressions

Leverages SSP partnerships (like PubMatic) to tap into direct supply paths

Improves campaign efficiency by cutting bid bloat and invalid traffic

Aligns media spend with business KPIs, not just proxy metrics like CTR

As supply path optimization becomes a key concern for 2025, Smart Supply is helping agencies future-proof their buying approach with transparency, efficiency, and scale.

The outcome

This approach led to a 50%+ reduction in CPA, significantly better traffic quality, and a more scalable, performance-first media strategy.
