Adding unique content to each collection page

Site URL: https://belvidore.com

Hello!

I am the founder of a luxury furniture brand in the US. I am reaching out because I am in need of assistance with my Squarespace website. My SEO team is unable to add unique content on different collection pages for my store.

For instance, when adding unique content to a specific collection like 'lighting', that content is shown throughout ALL collection pages (furniture, art, and bedding). How can I add unique content to each collection without it showing for other collections?

This is very crucial for SEO growth

I have attached screenshots for reference.
