How fast is fast enough?

Green Core Web Vitals means LCP under 2.5s, INP under 200ms and CLS under 0.1 at the 75th percentile of real users. We aim for comfortable margins because mobile networks vary.

Will you need to rebuild our theme?

Rarely. We quantify the achievable gain through optimisation first. Only if the theme architecture makes the target mathematically unreachable do we model a targeted rebuild and let you decide.

Do you optimise Pakistani mobile performance specifically?

Yes — we test on throttled 3G/4G profiles representative of local mobile networks, not just fibre desktop conditions, because that is where your customers actually are.

Core Web Vitals & Speed Optimization

Speed is the most predictable SEO and conversion win available. Every 100ms you remove from load time is measurable in both rankings and revenue — and unlike links, it is entirely within your control.

We work from field data (CrUX and Search Console), not just lab scores. Lab tools tell you what could be better; field data tells you what your real users on real Pakistani and international mobile networks experience.

Fixes span image pipelines, font loading, JavaScript splitting, critical CSS, server response, caching, CDN strategy and third-party tag governance. We implement directly and prove the improvement with before/after field data over a 28-day window.

The problems we fix

Red scores on mobile
Slow LCP and high INP on mobile suppress rankings and cause measurable bounce before your content is even seen.
Third-party scripts running wild
Chat widgets, pixels and heatmap tools routinely add seconds of main-thread work.
Plugin-stacking instead of fixing
Adding caching and optimisation plugins on top of a slow foundation makes debugging impossible and gains temporary.

How we fix them

Field-data-driven prioritisation
We target the specific pages and templates with real-user problems, ranked by traffic value.
Real engineering fixes
Image format and dimensions, font subsetting, script splitting, resource hints, edge caching and layout stability.
Prove it with field data
