Yes, If you use a light weight and optimized theme like GeneratePress, Astra, OceanWP or Neve, fastest load times can be achieved. Sites using a heavy theme like Avada or sites built with page builders tend to load slower on shared hosting. But I will optimize them as fast as practically possible.

Sites using cheap shared hosting are slower than sites using cloud based hosting like Cloudways or good hosts like Siteground or A2 Hosting (SSD storage). But I will optimize them as fast as practically possible. Hosts with LiteSpeed Cache does not work well or cannot be used with WP Rocket.

Having image sliders (Revolution), animations or site loader gifs above the fold prevents optimizing for Core Web Vitals. Also if your site is built with themes with heavy CSS/JS files or page builders like WPBakery, Elementor, Divi, it will affect load time. I'll apply steps to lower the effects.

No. But I might advise you to change, disable some features or use better options if you want to achieve faster load times.

While the work I perform will speed up the whole site, only the homepage of your website will be the main focus.
