Poor performance on mobile

Publishing help SEO
1

Hi, my site has a poor core web vitale score on mobile devices. The main page scores 5.3 seconds in FCP metrics. Really don’t know what to do. I am using compressed WebP and AVIF images, minified CSS, running the site through Cloudfare and lazy load Tag manager using a script detecting the user scroll, then loading the rest of the codes on the site. Still the performance is bad. Help, please.

Here is my site Read-Only: [LINK]1

Hi @Ondra_Linka ,

I tried your website on different Mobile size and the results are quite solide.

Can you share the Lighthouse score and what are the recommendations.
Or maybe you tried the test on a different URL.
