Feedback + referral to improve website speed performance

Hi everyone, 

One of my clients' website is facing a brutal drop in traffic: www.integrativeacupuncture.co.nz

1. Google search console indicates some pages are not indexed, including the homepage. I've tested the URL and the test is positive. I've submitted it twice now for reindexing - fingers crossed. Any suggestions on what I should do to prevent this
2. I've run a PageSpeed insight report and I'm getting a 29 for performance: https://pagespeed.web.dev/analysis/https-integrativeacupuncture-co-nz/awk8uuic7l?utm_source=search_console&form_factor=mobile&hl=en
   Could you recommend someone to help work this out? I don't necessarily have the bandwidth to learn how to deal with it so happy to hire a recommendation.
3. Is there anything else I should be looking at re-drop in traffic? 
   
   Thanks a lot for your help!

What changed? Is this a new website that replaced a previous well-performing website?

SEO Space is good at telling you what needs fixing on a website for SEO, but if this was caused by a change in website and URL structure without redirects that would need addressing first.

No it's the exact same website - nothing changed really apart from a few new blogs. The SEO test (from Page Speed insights) says it's at 97 so that part is sorted technically. 

The drop in traffic is from one month to another. 

I'm not seeing much of a drop-off of organic traffic, so if traffic has dropped off, finding where the traffic was coming from might help understand why overall traffic has seen a downturn.

Thank you so much for taking the time to check. I'm puzzled as this is what I was seeing from Analytics in Squarespace. What am I doing incorrectly? Guessing A) I should check analytics from GA or SEMrush 🙂 

More seriously, why is there a difference between the two?

And here's GA also showing a drop in April.

Organic traffic is just the portion that comes from search engines, a small fraction of the total.

This shows a drop but has picked back up to previous levels, I don't know what would have caused that, but with enough analysis in GA you may be able to find why.
