How can I improve my site speed and is it worth the effort?

[Alice_O_Connell]

My site speed is low, I have optimised imagery (using TinyIMG) and am running a version of my theme (Blockshop by Troop w/ mods) with Lazy Loading. Nothing is improving the speed and I am overwhelmed with confusion about what is the effective and trustworthy way to go.

And how much priority I should give this.

I can't accurately analyze my page speed as my url gets this response from Page Speed Insights:
Unable to resolve https://www.woolandwater.nl/. Try checking the URL for validity.

I have raised this with my domain provider 123Reg to understand why I get this response.

So here are my questions:
1) How big a deal are page scores?
Home 26

Product 28

Collection 27

2) If I update my theme to the latest version will I lose all paid for mods and will this even help improve the speed?

3) Where can I find a trustworthy dev to improve my page speed and what are the approximate costs to expect as a quote?

4) What is the best service to assess and understand what is slowing down my store?

Thank you in advance to anyone willing to share some insight and advice regarding this.
