Improve speed on google page insghts

Good morning, I’m a layman in the programming world but I would like tips to solve speed problems on my website, according to the report of PageSpeed ​​Insights:
My website spends 3.24 seconds just to remove unused Java escript. Who has tips and videos on how to improve loading speed? I would also like the site to process the above-the-fold data first and then scroll through .

Probably not the answer you want to hear but this is a forum dedicated to Corvid and you cannot use Corvid to minify css, remove unused js which shows up as alerts on your Google pagespeed insight report.

You best go through Wix Support as they ‘might’ be able to provide a solution. On this forum we can only provide solutions related to Corvid and your question does not relate to it.
