Impressions per page

Google Analytics

I would like to determine which pages of our site generates the most impressions. I can't seem to find that option.

All documentation leads me to Search Engine Optimization > Landing Pages. But this does not include certain pages we do not have index; hence do not act as a landing page.

What is the cause for a huge drop in impressions, could someone assist me with an answer to this question?
