Before/after tracking metrics
Do we need to rebuild the site to improve performance?Not necessarily. In most cases, gains come from targeted optimisations: assets, scripts, load sequence, cache, and rendering.
What's the real business impact?Better performance increases conversion likelihood and reduces mobile loss. 53% abandonment beyond 3 seconds is direct commercial impact.
Our Lighthouse score is already good, is the audit useful?Yes, because a global score isn't enough. We analyse the pages that truly matter for your conversion and business flows.
Will marketing tools be cut?We don't cut blindly, we prioritise. We weigh scripts by business value against performance cost.
Who drives implementation after the audit?Either your team executes with our plan, or we support remediation. Either way, we track progress on KPIs to secure gains.
