Hi,
our clients website has to rank higher in google so we are looking out for any stopping factor. On SEO platforms, we discovered that the website takes around 7.5 seconds to fully load on mobile, which by the way, isn't the realt loading time if you try to load it on your phone.
The size of the pages doesn't get above 3Mb.
Also other website we made don't get such bad results. Why do you think this does?
