Micro-testing philosophy slashes legacy CPE by -31%

Human-led, intelligence-driven challenger framework converts national pet insurance's legacy complexity into proactive, aggressive performance gains.

Taking over a legacy, multi-channel account requires a delicate balance: maintaining steady business volume while aggressively auditing the media mix to root out historical inefficiencies. When we partnered with a national pet insurance partner in March 2026, the primary directive was clear: apply our core philosophy of daily micro-testing and rigorous data accountability to transform a mature legacy footprint into a highly efficient customer acquisition engine.

Tactically, the reality is that legacy ad accounts often suffer from structural bloat, unrefined broad-match keywords, overlapping targeting layers, and a lack of clear bidding guardrails, all of which artificially inflate acquisition costs. Our initial audit of the legacy campaigns uncovered a massive opportunity. A website refresh in late 2025 had disrupted historical algorithmic learnings, leaving paid search campaigns operating on restrictive Target CPA (tCPA) models that choked impression share and drove up the brand's average CPC. Furthermore, deep analytical mapping revealed that the brand was over-indexing on expensive, lower-intent non-brand queries and failing to fully capture highly efficient direct brand search volume.

The Media Strategy

We executed a comprehensive account restructuring designed to eliminate keyword cannibalization and maximize audience intent across the full funnel:

  • Brand Search Breakouts: Restructured legacy brand search campaigns into distinct targeting groups: General, Reputation, and Comparison. This allowed the team to implement tight keyword guardrails, isolate pure brand terms, and safely test the point of synergy where paid ads supported organic SEO without duplication.
  • Algorithmic Reset: Shifted initial search and Performance Max (PMax) bidding tactics from rigid target goals back to Maximize Conversions and Maximize Clicks. This fundamentally reset the platform's machine learning, allowing the algorithms to serve impressions more freely and gather pure data density.
  • Asset & Placement Curation: Purged underperforming elements from Google PMax and completely re-engineered the asset groups by pet type (dog, puppy, cat, and kitten). High-intent video creatives were introduced directly into PMax experiments to capture premium visual placements.

The Measurement Strategy

True accountability means looking past simple, surface-level platform metrics to analyze real business results. Our analysts established a unified attribution layer to dynamically track user behavior across every stage of the conversion funnel.

When early tracking dropped in Google Analytics 4, threatening data clarity, the team cross-verified platform performance using strict Salesforce first-party conversion logic to ensure zero blind spots in optimization pacing.

As the fresh campaign architectures matured, the team layered back in strict, data-proven tCPA targets across Google Brand and PMax campaigns. This continuously challenged the bidding engines to prioritize maximum conversion quality rather than chase cheap, low-intent clicks.

The Results

Our philosophy of constant daily micro-testing and tactical refinements delivered an immediate, dramatic efficiency swing within the first 90 days of the takeover:

  • Dramatic Cost Reduction: Driven primarily by the Google Brand breakout, the holistic brand search average CPC plummeted -69% from its historical high.
  • Funnel Efficiency Gains: Click-to-enrollment conversion rates surged to 18.23%, marking a stunning +2.2x increase over the year-to-date baseline.
  • Profitable Growth at Scale: Blended search Cost-Per-Enrollment (CPE) dropped to an ultra-efficient $635. This represented a massive -31% reduction below the previous year-to-date average of $924, successfully positioning our national pet insurance partner to capture market share with unmatched cost efficiency.
