Hello @mariano,
Thanks for the thoughtful review and the constructive feedback, we really appreciate it!
You raise a great point about wanting more context behind the score. While Jetpack Boost currently shows the overall performance grade, the score is powered by Google’s Lighthouse engine, which evaluates key metrics like Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and more.
To understand what’s affecting your mobile score, here are some resources:
Even with Twenty Twenty-Five, mobile scores can be lower than desktop due to how Lighthouse simulates a mid-range mobile device on a slower connection, it’s a tougher test by design.
That said, your suggestion about including hints or a breakdown directly in the Boost dashboard is excellent feedback, and we’ve shared it with the development team. We’d love to make that experience less “flying blind” in the future!
If you want to deepen your 39 mobile score, feel free to contact us via this contact form and mention this thread. 🙂
Hey @erania-pinnera so many thanks for the reply, quick suggestion, just a “the score is powered by Google’s Lighthouse engine” could be a good place to start understanding how to improve 🙂
Now Ill try to find how to improve and then ill try to contact support (just improved to 59 yay!)
Howdy @mariano – thank you again for the feedback and the solid ideas on how we can improve our Jetpack Boost plugin for you and all of our users.
I’m also happy to hear that with some improvements on your end you have Boosted your score by 20 points since your original post. As always, if you want us to dig deeper with you and take a closer look you can feel free to contact us via this contact form and mention this thread.
hey @vitkory how are you? I’m improving bit by bit, now it says Mobile 73 and Desktop 100
The first thing was to turn on all the options on boost (including the LCP beta) second I’ve started using cloudfare since I was having a hard time with arehfs bot and some other attack; third ive started using the /more to avoid loading full posts on the home (honestly this was just a bet) and finally i’ve modified the theme a bit specially on the post footer (I think there were some nested tables that were not needed on the Date/Author/Archived in: footer)
Now, using PageSpeed Insights I have only one problem I dont know how to fix: “Cumulative Layout Shift” on Mobile (performance 83) and nothing on Desktop (performance 99) (Maybe some images are too big and they are switching size after loading… honestly Im old and rusty :P)
Hope this helps… and thanks again!
