Buy back mobile conversion with performance work
+12%
Mobile performance work usually stalls because the score is a single number and nobody knows which component owns it. This engagement attributes Core Web Vitals to specific elements and fixes them in the order their conversion cost justifies.
The process
Collect field data, not lab data
Real-user LCP, INP and CLS from the Chrome UX Report and a web-vitals script, segmented by device tier, network and template.
Attribute each metric to an element
LCP resolved to the actual image or text node, INP to the handler that blocked, CLS to the element that shifted — per template, not site-wide.
Price the fixes by conversion
Conversion rate read across performance buckets, so each candidate fix carries an estimated order impact and the queue sorts by that.
Ship in performance-budgeted batches
Image formats, script deferral, font loading and layout reservations shipped as small releases, each with a budget the build cannot exceed.
Hold the gain
Field metrics tracked weekly after release and a budget check added to the build, so the next feature does not quietly spend the win.
