Speed matters – not just for SEO, but for keeping visitors engaged and converting. In this case study, we show how we helped a New Zealand professional services business cut their load times by 50% using WP Rocket, one of the most powerful premium caching plugins for WordPress.
🏢 The Background
Our client runs a consultancy firm with a clean, modern WordPress site. It’s content-heavy, including:
- Embedded YouTube videos
- Large team profile images
- Blog articles with screenshots and diagrams
- Calendly and contact form integrations
The site wasn’t slow, but it wasn’t snappy either. First impressions matter – and their bounce rate suggested users weren’t sticking around.
📊 The Problem
After a performance audit, we discovered:
- Page load times averaging 3.4 seconds
- Poor Core Web Vitals, especially Largest Contentful Paint (LCP)
- Multiple render-blocking scripts in the header
- No page caching plugin in place
- Unoptimised CSS and JavaScript delivery
The server was performing well (hosted with us at Red Jet), but the frontend rendering was dragging down the experience.
⚙️ The Solution: WP Rocket Setup & Tuning
We recommended WP Rocket, and here’s what we implemented:
✅ Enabled:
- Page caching (for both desktop and mobile)
- Browser caching for static assets
- GZIP compression
- Lazy loading for images, iframes, and videos
- Preloading of cache and sitemap-based precaching
⚙️ Optimised:
- CSS delivery: Removed unused CSS and enabled async loading
- JavaScript: Deferred and delayed JS to eliminate render-blocking issues
- Database: Scheduled cleanups to keep things tidy
🔗 CDN:
They already used Cloudflare, which WP Rocket integrates with seamlessly. We simply ensured compatibility.
🚀 The Results
Here’s what we saw within 24 hours of deployment:
| Metric | Before WP Rocket | After WP Rocket |
|---|---|---|
| Page Load Time (GTmetrix) | 3.4s | 1.7s |
| Largest Contentful Paint | 2.6s | 1.1s |
| Google PageSpeed Score | 72 (mobile) | 96 (mobile) |
| Total Page Size | 2.8MB | 1.6MB |
| Bounce Rate (2-week trend) | 58% | 43% |
That’s a 50% improvement in load time, a dramatic UX boost, and higher PageSpeed scores across the board.
🧠 Why WP Rocket?
Unlike many free caching plugins, WP Rocket works out of the box, with minimal technical tweaking. For most business sites, it’s the fastest way to get faster – especially when paired with a quality hosting setup like Red Jet.
We love it because:
- It simplifies complex optimisations
- It doesn’t require extra addons or extensions
- It’s regularly updated and compatible with major themes/plugins
⚠️ A Word of Caution
WP Rocket is powerful – but misconfiguring it can break styles, forms, or interactivity. That’s why we configure it site-by-site, based on the theme, plugins, and use case.
If you’re not sure whether WP Rocket is right for your site, or if you need help configuring it correctly, we can help.
👉 Compare our hosting plans – we fully support WP Rocket on all of them.
Final Thoughts
This case proves that even well-built sites can become noticeably faster with the right optimisation plugin. WP Rocket is one of our favourite tools for performance and when combined with solid hosting, the results speak for themselves.
If your WordPress site isn’t as fast as it should be, we’d love to help you fix that. Speed wins online. Let’s make your site fly.
