A growth-stage SaaS company was generating 1,200+ monthly trials from Google Ads but fewer than 30 sales-qualified opportunities. The problem was not the ads. It was conversion tracking built around trial starts instead of CRM-qualified pipeline signals, campaign structure that collapsed intent layers, and Smart Bidding optimizing for the wrong outcome. This case study walks through the diagnosis and the fix: reconnecting GA4 to CRM for offline conversion imports, separating campaigns by intent tier, feeding LTV-weighted values into Smart Bidding, and building negative keyword architecture to block informational noise. The result was fewer trials, far better pipeline quality, and an account that finally optimized for revenue.
