PageSpeed optimisation service
Improve your Google PageSpeed score with fixes that stick
Chasing a number is not enough — you need changes that improve real load time, SEO, and conversions. We translate Lighthouse audits into work your team can ship, with before and after measurement for every change.
A low PageSpeed score is a warning sign: heavy images, slow servers, or JavaScript blocking the main thread before your content can render.
Aligned with Google PageSpeed Insights and real-user field data where available.
Why your PageSpeed score matters beyond the badge
PageSpeed Insights reflects how quickly your site becomes usable on mobile — where the majority of traffic and purchasing decisions happen. A weak score often means real users wait too long before they can read, scroll, or tap anything, and many leave before they ever see your content.
Search engines and ad platforms reward fast experiences. Teams that ignore scores typically pay more for the same traffic and see organic rankings plateau or decline as faster competitors pull ahead.
- Low mobile performance score correlates with higher bounce rates
- Render-blocking resources delay first paint and interactivity
- Unoptimised images are the most common quick win we see
- Third-party tags silently drag scores down over time
How we increase your PageSpeed Insights score
Every fix maps to a Lighthouse audit so progress is measurable.
Caching and CDN
Browser and edge caching so repeat visits and global users see snappy pages.
Code cleanup
Remove bloated themes, unused plugins, and render-blocking resources that slow every page.
JavaScript reduction
Defer non-critical scripts and cut third-party tags that delay interactivity.
Core Web Vitals
Target LCP, INP, and CLS with measurable fixes — not vague performance tweaks.
Lazy loading
Load below-fold media only when needed so the first screen paints quickly.
Font optimisation
Subset fonts, preload critical faces, and avoid layout shift from late-loading text.
Server response time
Tune hosting, database queries, and object caching so pages start rendering sooner.

How Loadzen helps you get faster
- 1
Audit
We run a deep speed and Core Web Vitals audit on your key templates — home, collection, product, and checkout where relevant. Every issue is ranked by its impact on real user experience and revenue.
- 2
Optimisation
We implement prioritised fixes: images, scripts, caching, and theme or app bloat — focused on revenue pages first. Each change is tested in staging and measured against a baseline.
- 3
Monitoring
You get ongoing checks so regressions from new apps, themes, or campaigns are caught before they hurt SEO and sales. Alerts fire when scores drop below your target threshold.

Frequently asked questions
Straight answers about timelines, risk, and what to expect.
- How fast can you improve my PageSpeed score?
- Quick wins often land in the first sprint. Bigger gains depend on hosting, theme architecture, and how many third-party scripts you run.
- Is mobile or desktop PageSpeed more important?
- For most businesses, mobile comes first — Google's indexing and ranking lean on mobile experience. We optimise mobile, then validate desktop.
- Why is my PageSpeed score different from real user speed?
- Lab data (Lighthouse) and field data (CrUX) can diverge. We use both: lab for reproducible fixes, field for what customers actually experience.
- Can you fix a low PageSpeed score without redesigning my site?
- Usually yes. We start with images, caching, fonts, and scripts before recommending a redesign.
- Do you guarantee a specific PageSpeed number?
- We guarantee a structured plan and implementation of agreed priorities — not arbitrary numbers that ignore your stack constraints.
