How to increase impressions

new to this

I do not understand how to get the impressions to increase. I have several sites, 3 of which are blog accounts and one is our store site. I am trying to figure out how to get the impressions to increase. Do you have to have more content on the site or what? Any advice would be helpful

Get more (legitimate) traffic - it's the only reliable and safe way.
