1) Optimize images that you use on your site https://prnt.sc/1vufa0h Many of the images that you use are too large. You can try https://tinypng.com/ service to optimize images. Also, don’t use images larger than it’s needed. For example, your logo in footer is 3000 × 2100px when block, where you use it, is just 165×115 https://prnt.sc/1vufvsk
So, why do you use the huge image for that block? And so on.
2) Reduce the number of scripts on your site https://prnt.sc/1vuf41t It means that you need to check the list of plugins that you use and disable plugins that you don’t need. For example, do you plan to use newsletters on your site? If not then disable the Mailchimp plugin because the plugin script loads a lot https://prnt.sc/1vugmbv etc.
3) Use JS and CSS modification, it speeds up the site speed as a rule (but check if everything works as expected because I see a number of third-party plugins and I’m not sure if all of them support modification).
