This is a really good plugin, it makes you remember stuff you might left behind and so on.. however when you get a “Mobile Score 39” you are flying blind, since there is not a single clue why is that number that…[new tip: the score is powered by Google’s Lighthouse engine thanks for the data ]
Im not asking for the solution, that might be a great add-on to upsell but, now im only thinking: “Why on earth im 39 on mobile if im using the twenty twenty five plain vanilla template? what have they left out?”
So, I would say including some hints might boost my review at least one full point. thanks!
Great extension. The Boost feature is great
Very easy to use and sped up the LCP considerably. It’s hard to tell when I actually need to regenerate the critical CSS and kind of slow to do it but that’s a minor concern.
