The Project
A UK professional services firm had a Lighthouse score of 41 and an LCP of 6.8 seconds — costing them ranking positions and leads. We conducted a full performance audit and implemented image optimisation, JavaScript code splitting, critical CSS inlining, and edge caching on Vercel. Lighthouse score went from 41 to 96 in two weeks.
