Unlocking Smarter Growth: How Lighthouse Outperformed a Top Amazon Ad Tool for a $700M Seller

When you’re a $700M Amazon seller spending $20M a year on ads, the stakes are high. For this retailer, even with one of the leading bidding tools and a large in-house marketing team, performance had stalled. Costs were rising, and campaigns couldn’t adapt fast enough to changing business goals.

That’s when they chose Lighthouse.


The Situation: Growth Stalled Despite Heavy Investment

Despite their size and resources, this seller faced a familiar challenge:

  • Flat Results – Ads weren’t scaling profitably, despite millions spent on a top bidding tool.

  • Rigid Optimization – Tools struggled to adjust to shifting revenue vs. profit priorities.

  • Complex Portfolio – Thousands of ASINs, many with little or no ad spend history, created untapped opportunity.

They needed a more data-science-driven approach—one that could continuously balance profit and growth.


The Lighthouse Solution: Dynamic Financial Optimization

Within days of onboarding, Lighthouse applied its Dynamic Financial Optimization framework:

  1. Automated Restructuring – Campaigns were rebuilt for keyword-level bidding, tuned to each individual ASIN.

  2. Granular Modeling – Lighthouse measured spend elasticity and conversion rates at the ASIN-Keyword-Placement-MatchType-Hour level, modeling profit and revenue trade-offs.

  3. Phased Rollout – We began by maximizing profit across the catalog (Phase 1), then shifted into revenue acceleration mode with Lighthouse SalesBooster (Phase 2).

  4. Statistical Rigor – Performance was validated through a balanced A/B test to confirm significant gains.

The Results: Profit First, Then Scaled Growth

Lighthouse delivered transformational results in both phases:

Phase 1 – Profit Maximization

  • 70% lift in attributed sales while lowering Ad Cost of Sales (ACoS) from 18% → 7%

  • +7% profit lift at the portfolio level

  • Prevented profit dilution by eliminating excessive bids

Phase 2 – Revenue Acceleration

  • +160% lift in attributed sales

  • +14% revenue lift overall

  • Cold-start ASINs—previously untapped—generated +14% revenue and +5% profit at a highly efficient 7% ACoS

  • Kept ACoS below pre-launch levels, despite higher sales volume


Why It Worked

Unlike traditional tools, Lighthouse doesn’t just chase clicks or sales volume. Our system:

  • Models elasticity at the product level to find the true “profit vs. revenue” sweet spot

  • Seamlessly shifts between financial objectives (profit vs. revenue acceleration)

  • Adapts dynamically to new product launches, Buy Box competition, and market conditions

The result? More sales and more profit, with efficiency that scales.


Takeaway for Large Sellers

For high-volume sellers spending millions on Amazon, even small gains in efficiency translate into millions of dollars in profit. Traditional bidding tools plateau. Lighthouse’s adaptive, profit-first approach breaks through the ceiling.

When performance stalls, the question isn’t how much you’re spending—it’s whether you’re spending it the right way.
