Does it make sense to use noindex in my case?

Question

Search Engine Optimization

I have articles on the site and there are links in the text from the main navigation menu, is there any point in hiding them?

Answer 1

It is desirable to close duplicates from indexing. Multiple repetition of short phrases can cause a reaction in Yandex in the form of an NCL filter.
But the final decision must be made based on the analysis of the residual volume of content and its text parameters. If you make a decision at random, without statistics on the text, you can do harm.

Answer 2

No, why would you? If the site links to itself, it's even good.
