Page Speed Insights Performance Issues HELP!

Hello all

I've just developed my first squarespace website and I'm trying to max out the SEO. I've used Page Speed Insights to help me spot any issues, and I'm working through them to see if there is anything I can do to correct them.

I have posted images of the issues:

OPPORTUNITIES
Reduce initial server response time – 0.68s
Reduce unused JavaScript – 0.52s
Eliminate render-blocking resources – 0.32s
 

DIAGNOSTICS
Ensure text remains visible during webfont load
Image elements do not have explicit width and height – Logo
Serve static assets with an efficient cache policy

Which of these can be fixed?

And, if any can be fixed, any support would be greatly appreciated.

Please be aware that I'm not a coder whatsoever.

Thanks

The suggestions in the PageSpeed Insights report are not within your control. You'll need to rely on the work that Squarespace engineers are doing centrally to improve performance across all sites.

For factors within your control,  take a look at these Squarespace support guides:

• SEO checklist
• Increasing your site’s visibility to search engines

i've fixed a few on the original report. Is it just these ones that are not under my control?

My mate thinks he may be able to write some code to fix the  'Ensure text remains visible during webfont load' issue.

@Eidronis this video might help: 

I've done everything in this video, and my score is still 30. Squarespace's JS is taking 1400 ms to load!

Will this ever be fixed or do I have to move away from Squarespace? I've been frustrated by this issue for over 4 years now and I always hoped they would fix it but it doesn't look like it's going to ever happen.
