How a National Sporting Goods Retailer Cut CPA by 55%

A national sporting goods retailer brought Trevant in to take over their dynamic ad program mid-flight... from a long-term agency partner... during their largest initiative of the year.

The stakes were real: a botched transition meant interrupted momentum on a campaign that couldn't afford to stall.

The mandate: don't break what's working, but also make it better.

Before touching anything, Trevant audited the existing campaign structure to establish a clear performance baseline — what was working, what wasn't, and where the ceiling was. That audit shaped the action plan: identify the highest-leverage optimization opportunities first, then rebuild the budget flighting approach to support scale without sacrificing efficiency.

The priority wasn't to overhaul the program. It was to earn the performance gains that would make scaling safe, then grow spend on top of a stronger foundation. Optimizations ran continuously throughout, with budget allocation adjusted as performance data came in.

CPA dropped 55%. CVR increased 25%. Average order value grew 9%. Spend scaled 69%. January — typically a pullback month for retail advertisers — ended as a growth month.
