Q3 2025 to Q3 2026 YoY: Like-for-Like Comparison, ad spend flat for both time periods.
Ad budgets were static when comparing Q3 between years. With a goal of growth, we refocused on new creative, optimized and A/B tested the campaign structure and assets, and continuously improved the landing pages to deliver clear value to customers. That led to higher click-through rates, higher conversion rates, and in turn customer and revenue growth.
Doing all of this on the same spend delivered not only growth, but improved margins along with it.
Notes: Paid campaign management began May 2025, so Q3 vs Q3 is the cleanest YoY comparison for campaign efficiency.
