I've hit a self-set personal milestone put in place since I joined Ezoic at the start of this year: to have all Core Vital Statistics be in the green zone for both desktop and mobile.
I've had desktop in the high 80s/low 90s for a while but LCP for mobile was hovering just above the green zone until a couple of days ago.
Just to say that you won't see immediate results from LEAP, as it doesn't work that way, but it is definitely worth sticking with and implementing all the recommendations, particularly if you're using a CMS like WordPress which can be bloated by default or become bloated by lots of poorly performing plugins.
As much as anything, the scores shown are a 28-day rolling average so improvements will take a little time to filter through to the overall score. However, after four full months of using the system I can see that things are definitely moving in the right direction.
A lot of the changes requires are quite simple and quick to implement, it can just take time to see the results. But do stick with it as most of the hard work is being done behind the scenes meaning you don't have to sort out your own plugins, web host caching settings and so on. It just works.
