Our testing methodology includes two separate data sources: CrUX (Chrome's User Experience Benchmark Report) and PageSpeed Insight.
CrUX is based on real data from Chrome users. We collect Core Web Vitals (LCP, FID, CLS, INP), as well as First Contentful Paint and Time to First Byte. This data reflects the actual performance of your site under real-world usage conditions.
We also leverage Page Speed Insight data to derive the Page Speed Score and Speed Index. This data is generated by “synthetic” testing. This allows us to obtain an objective and consistent assessment of site performance, independent of actual user activity.
By combining these two approaches, we get a holistic view of your website's performance.

Which metrics you should rely on depends heavily on your specific goals and needs.
If you want to get a global view of your web performance to position yourself in relation to your market or to easily share a status of your web performance with your internal teams, the PageSpeed score is an interesting option. It is calculated from an algorithm that integrates several metrics and allows you to have a macro view of your performance.
On the other hand, if your main goal is to improve your SEO, then Core Web Vitals are essential. These metrics have been integrated into Google’s ranking algorithm since the Page Experience update. Core Web Vitals include indicators that measure crucial aspects of the user experience: page loading, interactivity, and visual stability. In addition, Time to First Byte (TTFB), which reflects the server response time, also plays a crucial role in SEO optimization, as it directly impacts your site’s crawl budget.
At Fasterize, we also analyze First Contentful Paint / Start Render and Speed Index. These metrics are directly related to how your visitors perceive the loading speed of your site.
Finally, if your goal is to improve your conversion rates, all of these metrics will need to be observed since they are all linked to user experience.
In conclusion, choosing the right metrics depends on your specific goals: PageSpeed score for an overview, Core Web Vitals and TTFB for SEO improvement, and First Contentful Paint / Start Render, as well as Speed Index, to ensure an optimal user experience.
To assess the quality of your web performance, you will find in this diagnosis a scale for each metric. According to Google's criteria, your site will be classified as "good", "average" or "bad" depending on its results on these metrics. A "good" ranking indicates that your web performance is solid and can have a positive impact on your SEO and user experience. An "average" ranking suggests that there are improvements to be made to optimize performance. Finally, a "bad" ranking means that serious problems need to be resolved to improve the speed and user experience of your website.
Comparing your website performance to your competitors is essential to gaining a holistic view of your market positioning. This benchmarking will help you identify your strengths and weaknesses, spot opportunities for improvement, and areas where you could stand out.
