Global pet food brand slashes CAC by 80% with Google Ads to Amazon

Challenge: Soaring customer acquisition costs

The pet food brand faced exceptionally high DSP-based acquisition costs, $317 per customer, which limited scale and profitability. In a fiercely competitive online market, this CAC eroded ROI and constrained growth opportunities.

Strategy: Google Search Ads to Amazon

Ampd implemented its intelligent bidding platform to route highly intent-driven Google Search traffic directly to the brand’s Amazon listings. Leveraging deep linking and Amazon attribution, the solution ensured conversion‑optimized placements and eliminated DSP intermediaries.

Execution: Automation & attribution

Ampd’s platform deployed real-time bid automation across hundreds of targeted keywords. Each click was tracked end-to-end, from search query to Amazon purchase. This allowed dynamic budget allocation toward high-performing keywords and audience segments.

Outcome: Drastic reduction in customer acquisition costs

The campaign achieved dramatic results:

• CAC fell by 80%, from $317 to just $64
• Google Ads drove scalable, trackable revenue to Amazon
• The brand gained full visibility into ROI and keyword efficiency

The client achieved their most aggressive growth goals by slashing acquisition costs and scaling efficiently across Google search. Achieving $64 CAC versus a $317 benchmark empowered the brand to confidently reinvest in campaigns, targeting new segments with confidence and clarity.
