Jetpack Boost optimizes your website’s performance, using Lighthouse to deliver accurate speed scores and enhance user experience.
How my page speed score is measured?
Our speed scoring system runs on our servers using Lighthouse for precise web page performance evaluations. This methodology, trusted across the industry and utilized by platforms like pagespeed.web.dev and Chromium-based browsers, assesses crucial factors, including load times, interactivity, and visual stability. By integrating Lighthouse into our infrastructure, Jetpack Boost ensures accurate speed scores that reflect your website’s performance.
Why do my site’s speed scores differ from Lighthouse?
Jetpack Boost uses the same Lighthouse engine as Google PageSpeed Insights, but differences can occur due to test server location, timing, or network conditions.
Why has my site’s speed score recently changed?
You might have noticed an update in your site’s speed score recently, a direct result of Jetpack Boost embracing the advancements in Lighthouse version 10. This evolution from version 9 brings a forward-thinking approach to how speed scores are determined, especially with the strategic shift away from the Time To Interactive (TTI) metric, towards a greater focus on Cumulative Layout Shift (CLS). This means CLS now plays a more significant role, making up 25% of the overall performance score.
Why is this change good for your site? By prioritizing visual stability through CLS, we’re aiming to enhance the user experience on your website. This not only aligns with the latest web performance standards but also ensures your site’s performance score is more reflective of what truly matters for both users and search rankings. With these changes, your site’s speed score may shift. While some sites will observe an improvement, reflecting a better alignment with Core Web Vitals, others might notice different results. This variance underscores our commitment to providing a holistic view of site usability and performance.
We understand changes like these can raise questions. For a deeper dive into how Lighthouse 10’s updates positively impact your site’s evaluation, we invite you to explore Google’s detailed documentation on the Lighthouse 10.0 update. These changes, effective as of April 4, 2024, are part of our continued commitment to leveraging the most current and impactful web performance evaluation methods.
