Page regions, headings and structure: screen readers and accessibility

I am currently designing a website, and we had a vision impaired person audit the site for accessibility issues. The person was using a screen reader, and their biggest issue was that the site was not organized logically with the use of regions and headings. For reference, they provided me with this resource to better understand this: https://www.w3.org/WAI/tutorials/page-structure/regions/

I am using version 7.1 so I do not have access to the advanced developer tool. I have some coding knowledge, but through my research so far, I do not know for the life of me how to make these changes.

I think I have to define the page regions, and clarify headings. I've used different templates for different pages as well, so I am anticipating I can't put in just a blanket code. 

I'm not sure if this involves code injecting. Any help or recommendations would be greatly appreciated!

Hi @Nevadajesse- I think Accessibility is becoming more and more critical for business owners. Just the other day a company has approached me for a new website and wondering how Squarespace can help satisfy Accessibility issues eg. visual impairment, over and above what's contained in the support article.
