Drupal 8 tags and categories cause duplicate content shown in MOZ

[Optimal_Strategies]

Hi all,

There is something difficult to trace that is causing duplicate content that is related to categories and tags i.e.

example 3

https://example.com/tags/test

https://example.com/tags/test-2

Above two pages display same content (maybe due to similar posts feature)

My question here is: Is this caused by Drupal website misconfiguration (or one of its modules) since website uses similar posts feature or it's something else.

Duplicate content for example.com/index.php issue has been solved by redirects. Should something similar be done in case of tags / categories?

Any discussion / suggestions on that matter are greatly appreciated. Thank you.
