Hidden page impressions are affected on website ranking?

I have a website which has good rank in SERP.
But the question is that, iโ€™m not showing some pages of my website which is not more useful or less important pages. So, it consider as a hidden content or affect on my website ranking?.

One more thing, these pages also get some impression.

Sorry, this question is best asked on another forum, we donโ€™t cover SEO topics here.
