How to solve multiple core web vitals issues on my site?

SEMrush, the SEO analysis platform, is flagging multiple core web vitals issues on my site, resulting in a “Largest Contentful Paint” of 6.50s +0.75s:

  • Ensure text remains visible during webfont load
  • Eliminate render-blocking resources.
  • Remove Unused JavaScript

Of course, as a non-coder and a nontechnical person, and given that all these issues are presumably a result following from the code that Webflow is generating, I have no understanding of how to address them.

Might anyone have any advice as to how pursue a solution to this?
