Howdy @tgrblogger! Thank you so much for taking the time to share your feedback with us. I completely understand how confusing it can be when performance metrics from Jetpack Boost don’t seem to align with what you’re seeing in tools like you mentioned, SEMrush and pagespeed insights.
Jetpack Boost is designed to measure and highlight site performance indicators directly from your visitors real browsing experience – this can sometimes differ from data provided by other third party tools. Jetpack Boost uses Lighthouse, an open-source tool by Google, to test your site just like PageSpeed Insights.
If you would like to share more information about the difference in scores that you are seeing, we will be happy to investigate further. You can share details in this thread or if you prefer to speak with us in private to share your site details, please contact us here.
