I did a lot of Googling, but I did not seem to find something on the topic. According to this thread this question needs to be asked here.
I'm using a WordPress installation with a theme that renders the navigation as links. It also renders tags and categories as links. When I'm doing a Google search with "site:", I see that the navigation/overview pages are shown first (pages like date-pages, category-pages and tag-pages). Bing does a slightly better job, but still shows a lot of these overview pages.
How can I make overview-pages less relevant to search engines like Google and Bing?
