Marek Hey Marek, 'website speed' can mean many different things. At Ezoic, we are only really concerned with Core Web Vitals, as this is the only speed metrics used by Google to rank sites. Traditional site speed metrics like 'total time for page to load' are outdated and not really something to be concerned about.
I recommend you utilise Leap and it's technology to help improve your sites Core Web Vital metrics, I'll leave some guides below to help you get started with Leap. Whilst this will help, I do want to point out that using Elementor on the site is going to limit the amount you can do to optimize your site speed. Elementor adds a large amount of css and javascript to all of your pages and will ultimately slow the site down. If you really want to see some improvements here, I recommend moving away from using Elementor.
