Is it worth it to close the page with the output of all news from indexing?

Question

Search Engine Optimization

at the address "/news" a list of all news is displayed. Should it be hidden from the robot?
I also wanted to clarify whether it is necessary to close the widgets that are on all pages?

Answer 1

In short: No, you don't.
However, it makes sense to close pages with a list of news from indexing by parameters (tags/categories/dates) - of course, only if you have a main list of pages (with pagination, for example).
