Performance optimisation
Page speed testing
Understand how your site loads, renders, and responds - so you can make focused improvements that boost UX, improve SEO, and drive business growth.
Deliver faster, smoother websites
Page speed testing measures how quickly your website loads, renders, becomes interactive, and responds to real users in their browsers.
By identifying front-end issues like heavy scripts, render-blocking resources, and unoptimised images - as well as back-end challenges such as slow server response and database bottlenecks - we help you prioritise fixes that improve load speed, reduce latency, and deliver a faster, smoother user experience across all devices.
'Since we started working with the Zoonou team back in 2019, we have seen a real benefit from our open and collaborative working relationship and Zoonou has become a key partner for helping us to deliver quality digital products to our clients.'

Our page speed performance testing services
Whether you're looking to improve SEO, reduce bounce rates, or increase conversions, our page speed performance testing service provides the foundation to make faster, smarter, user-focused decisions.
We use a comprehensive suite of open-source tools to carry out in-depth page speed testing. This allows us to test individual pages or entire user journeys, collecting a wide range of browser and visual performance metrics.
Using automated browser tools and Selenium scripting, we simulate real-world user interactions - from simply loading a page to submitting forms. This enables us to capture key timings such as page load time and last visual change, and to evaluate how your website performs during typical user actions.
You'll receive a detailed report, broken into three sections, providing insight into different technical aspects of your site's performance:
Metrics: this section presents a thorough breakdown of browser-reported data and visual timings, calculated through video analysis of the page load process.
Filmstrip: a timeline of screenshots captured during page load, helps to identify layout shifts and rendering issues that could affect user experience.
Coach: the most actionable part of the report, the coach section provides automated suggestions across three categories: performance, privacy, and best practices.

Speed and stability go hand in hand
Page speed performance testing helps you deliver smoother, more engaging user experiences. But speed alone isn’t enough. When traffic surges, can your site keep up?
That’s where load testing comes in. It ensures your back end is as ready as your front end, so your site stays fast and reliable under pressure.
