The metrics that matter

Google measures real-user experience through Core Web Vitals. We target the thresholds that count as "good".

LCP: loading

Largest Contentful Paint within 2.5 seconds, so the main content appears quickly.

INP: responsiveness

Interaction to Next Paint under 200 milliseconds, so the page feels instant.

CLS: stability

Cumulative Layout Shift under 0.1, so content does not jump around.

Speed is a ranking factor and a revenue factor

Page experience is part of how search engines evaluate sites, and users abandon slow pages quickly, especially on mobile. Faster pages tend to rank, convert and retain better.

We approach performance as engineering, not a plugin. We measure with field data and lab tools, locate the real bottlenecks and fix them in order of impact.

  • Lighthouse and PageSpeed baseline
  • Real-user monitoring set-up
  • Prioritised fix list with impact
  • Before-and-after reporting

Common culprits

Images
Oversized, unoptimised
Scripts
Render-blocking JS
Server
Slow TTFB, no cache
Plugins
Bloat and conflicts

What we optimise

  • Image compression, responsive sizes and WebP/AVIF formats
  • Lazy loading and priority hints for above-the-fold content
  • JavaScript and CSS minification, splitting and deferral
  • Critical CSS and font loading strategy
  • Server response time, PHP version and database queries
  • Page, object and CDN caching
  • Third-party script audit (tags, chat, analytics)
  • Plugin and theme bloat reduction

FAQ

Website Performance: frequently asked questions

The usual causes are large images, too many scripts and plugins, slow hosting, missing caching and inefficient database queries. A performance audit identifies which apply to your site.

Yes. Page experience signals, including Core Web Vitals, are part of search ranking systems, and slow pages also increase bounce rates, which hurts conversions.

In most cases yes. Image handling, caching, plugin clean-up, hosting and code improvements often deliver large gains without a rebuild.

If the platform itself is the constraint, we will tell you and propose a path, such as moving to a lighter theme or a headless Next.js front end.

Yes. We provide before-and-after scores, field data and a summary of every change made.
