Wasted spend identified via attribution pipeline

The Challenge

Stackline was spending $40k/month on paid ads but their landing page conversion rate was stuck at 1.2%. Page speed scored 38 on Core Web Vitals, and there was zero attribution tracking.

Our Solution

Complete rebuild on Next.js with hardened security headers, sub-1.2s LCP, and a multi-variant CTA system. We instrumented every interaction with GA4 micro-conversions and built a custom attribution pipeline feeding back into their ad spend optimization.

The Outcome

ROAS jumped 2.8x within 6 weeks. Page speed hit 98/100 on Lighthouse. The attribution pipeline identified $18k/month in wasted ad spend that was reallocated to high-performing channels.
