Question re Google search results for Squarespace website

Hello,

I did a Google search for my website using my phone and got this result.

A few questions.

1.  See how the description of the "home page" is simply the Menu Bar items of the home page.  Is there anyway to change this to a meaningful description? 

2.  Also, for items below the home page, can we customise what's displayed. 

3.  Can we also control the order of the results displayed.  eg.  "Memberships" is probably the Nbr 2 result we would want after the "home page". 

Any advice would be appreciated.

Thanks.
