The challenge

Amazon Business Placements Converted Best, But Only Got 5% of the Budget

Carbyne Tools is a family-run US tool brand, run by Scott Huntress. Its bit socket and hex key sets sell to the trades: business buyers were already 30% of sales, but there was still untapped opportunity. In the 90 days before Viral Tilt, sales were down about 20% on the year before, and they needed a new avenue to spur growth.

Amazon Business placements ran efficiently, at an ACOS 70% below top of search, yet only received 5% of ad spend. The account’s ACOS was 1.6x what it had been a year earlier. On 9 Feb 2026, AdLabs introduced Scott to Viral Tilt.

The approach

Strategic Optimization Built Around the Buyer.

Viral Tilt focused the account on business buyers and used AdLabs to roll the changes out across the catalog.

  • Clear the Waste First.

    Viral Tilt cleaned up the account first, so new budget had somewhere better to go.

  • Bid Where Businesses Buy.

    Bids moved toward business buyers across the catalog with AdLabs.

  • Give Business Buyers Their Own Campaigns.

    Dedicated campaigns for business buyers.

Weekly business and consumer sales, 4-week average, indexed to the average week of 17 Nov 2025 to 15 Feb 2026 = 100. Business sales step up from mid-March and stay about 3 times the base or more; consumer sales rise far less.

The step-up came on 19 Mar, the same week Viral Tilt rewrote the listing copy.
