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.
Technology Stack
“We went from guessing to knowing exactly where every dollar of ad spend was going. Ghost gave us a competitive edge.”
