A top‑5 pet food brand transforms customer acquisition using Ampd’s automated bidding & closed‑loop attribution.

Here's how:
1. Challenge: Soaring customer acquisition costs

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.

By combining intelligent bidding, closed‑loop attribution, and direct retailer traffic, Ampd enabled a major pet food brand to transform its customer acquisition funnel, delivering lower CAC, full ROI visibility, and sustainable growth.
