SEO doesn't work

Site URL: https://www.livehaughilton.com/

My SEO dosen`t come up when I google my website, why?

I changed it in Marketing, SEO, then changed the SEO site description in HOME.

Have I done something wrong?

Hi there,

Im a newbie at site design and SEO but have just gone through the same process. I have checked and you do seem to be in google:

To see if you're actually indexed, search as per the picture in a google search bar: site:[yoursite] , however, actually getting your site to appear for different keywords is a different matter and that is the core process of SEO. Id recommend you download Google search console to monitor your progress. It will show you which pages Google has indexed and which keywords you are being indexed for. 

Hello, 
I'm sorry to ask this question but I can't figure out how Squarespace works regarding the display of pages when I do a Google Search, or is it just me who is not doing the right thing.
I would like that when I google my site, only 3 subtitles appear. I have deactivated the pages that were initially displayed but nothing works.
Do you have any idea how I can do this?
Sincerely
