Case Study: International SaaS Company cuts ad spend 87% and boosts profit 3.5% with LiftLab

How LiftLab Helped an International SaaS Company Decrease Ad Spend by 87% and Increase Profitability by 3.5%

International SaaS Company engaged LiftLab to evaluate whether its Google branded search campaign was overspending on new customer acquisition. LiftLab used its science-driven marketing optimization approach and ran a geo-based experiment (testing regular, reduced, and doubled spend levels) to measure true incremental return given the client’s high impression share (85–90%).

LiftLab generated a diminishing-returns curve that identified an optimal daily ad spend of $2,108 (vs. the client’s $16,156), enabling an ~87% cut in ad spend while only reducing orders by ~2%. The experiment also lowered CPC by ~48% and increased profit by 3.5% (from $248,486 to $257,183), giving the International SaaS Company clear, data-driven guidance to maximize ROI.
