What’s the typical ROI on a performance project?

Two compounding revenue effects. (1) Conversion lift: stores typically see 8–25% uplift within 90 days post-optimisation, before any UX changes. Google’s own research shows every 100ms of LCP improvement = ~1% conversion gain in retail. (2) SEO lift: rankings improve over 6–12 weeks, which compounds the conversion gain because you’re also getting more traffic. Plus a one-off cost saving: most stores can downgrade hosting after the optimisation (CPU/RAM headroom that was masking the inefficiency is no longer needed) — we’ve seen 30% hosting bill drops. On a $1M/yr store, even a conservative 8% conversion lift covers the Full Optimization fee in under a month.
