Why it matters
Built to move the metric you actually care about.
Core Web Vitals green
LCP under 2.5s, INP under 200ms, CLS under 0.1 — the three Google watches, fixed end-to-end.
Real device testing
Mid-range Android on 4G is the benchmark. If it flies there, it flies everywhere.
Measurable revenue
Every 1s faster mobile PDP = ~7% CVR lift on average. This pays for itself in weeks, not months.
Use cases
When to reach for this.
Failing Core Web Vitals
Google Search Console flagging your URLs as 'Poor' or 'Needs Improvement'.
High mobile bounce
Mobile bounce rate 10%+ above desktop — usually a speed or rendering issue.
Theme bloat
Years of added apps and sections — slower every install. Time for a controlled cleanup.

FAQ
Quick answers.
Will you remove my apps?+
Only with your approval — and only ones genuinely unused. We audit, show you the blast radius of each, and you decide.
How do you measure?+
PageSpeed Insights + WebPageTest for synthetic, real-user Core Web Vitals from your Search Console and GA for field data.
Does this affect SEO?+
Yes, positively. Core Web Vitals are a confirmed Google ranking factor since 2021, and faster pages earn higher CVR — which Google also notices indirectly.
