The situation
A slow legacy storefront was suffering from 4.8s mobile load times, high bounce rates, and inability to rank for localized high-intent search queries.
What we did
- Decoupled frontend onto Next.js with incremental static regeneration (ISR) for instant page transitions.
- Generated 250+ programmatic landing pages targeting long-tail commercial search intent.
- Deployed server-side PostHog tracking to recover 35% of lost attribution data caused by ad blockers.
