Regarding all the demo/imported pages

Hi…
I have imported Woodmart demo content site template pages/products. Now I see 137 ‘published’ pages and lots of ‘published’ storefront pages (eg Home Digitals) in my WordPress.

Q: should I set all the unused pages (eg Brands Element) and storefront pages to ‘Draft’ to avoid them all getting indexed as spam by Google? I don’t really want to delete as I may need the elements/html in those pages?

Thanks
Edward
