Recommendations
GTmetrix uses Google's Lighthouse - the modern standard in web performance to assess your website's performance and provide comprehensive, easy-to-understand recommendations and reports.
About Lighthouse
Lighthouse focuses on user-centric metrics. That means our tests measure a number of performance metrics that reflect what your site visitors would actually experience as your page loads.
This helps you develop a website that is not only loading fast but also feels fast in the perception of your visitors. We encourage you to learn more about these metrics and audits through our detailed documentation.
We also provide simplified guidance on what you should focus on, in the interest of optimizing the website experience for your visitors.

If your site is slow, your users will leave
Speed is a crucial aspect in providing a pleasant user experience to visitors of your site. It ensures that a visitor's limited attention span and time are spent on actual content and not wasted waiting for images and scripts to load.
Speed is even more important for mobile device users, as studies have shown that users are unlikely to tolerate more than a 3 second page load time on a mobile device.
Performance and SEO
In terms of SEO, Google already uses both 'Page Speed' and 'Page Experience' in their ranking algorithm. Google also mark high-performance pages as 'Fast pages'. As developers and marketers look to optimize their sites, Page Speed and Page Experience should be among the top optimizations to consider.
Despite this, however, Google has made it clear that even though Page Speed and Page Experience are important, they will continue to prioritize pages with the most relevant and quality content overall.
Therefore, don't do it just for SEO, do it for your users!
