Background
As part of our ongoing commitment to delivering high-performing websites, we recently conducted a performance audit of Cooney & Conway’s website using Google’s PageSpeed Insights. While the original site speed clocked in at 4.4 seconds, our goal was to optimize performance to pass Google’s Core Web Vitals, which is a key factor in search visibility and user experience.
Goal
Improve website performance to enhance user experience and SEO.
Objectives
- Reduce page load times
- Pass all three Core Web Vitals benchmarks
- Improve responsiveness and visual stability
- Maintain a seamless experience across desktop, tablet, and mobile devices
What Are Core Web Vitals?
Google’s Core Web Vitals are real-world metrics that measure key aspects of user experience:
- Largest Contentful paint (LCP): Measures how quickly the largest content (typically a hero image or headline) becomes visible.
- Result: 2.1 seconds (well below the 2.5s target)
- Interaction to Next Paint (INP): Tracks how fast the site reacts to user inputs.
- Result: 137ms (excellent)
- Cumulative Layout Shift (CLS): Detects unexpected layout shifts during loading.
- Result: 0.00 (perfectly stable)
Approach & Solutions
To bring site performance up to speed, we made several targeted improvements:
- Image Optimization: The homepage hero image was configured to load differently based on device type, improving load efficiency on mobile, tablet, and desktop.
- Image Preloading: Key visuals were preloaded, so they begin rendering as early as possbile.
- Script Optimization with NitroPack: We prioritized critical scripts and deferred less important ones, such as translation scripts (GTranslate), to reduce delays.
- Performance Monitoring: Automated tools like Lighthouse flagged potential areas for enhancement – but these are based on simulated slower conditions. Real-user data shows significantly better performance.
Results
While Lighthouse may show an LCP of 3.4 seconds due to its conservative testing parameters, real-world user data tells a more accurate and encouraging story.
- Site load time reduced from 4.4s to under 2.1s
- Passed all core web vitals
- Enhanced user experience and SEO positioning
Conclusion
By strategically optimizing media, prioritizing important resources, and fine-tuning performance with NitroPack, the Cooney & Conway website is now faster, more stable, and more responsive than ever. This strong performance foundation ensures better search rankings and a seamless experience for users on any device.
We’ll continue to monitor and refine the site to stay ahead of future performance standards.
