I keep reading about impressions and clicks; for some reason it is just not making sense to me. Can someone please explain an impression. I thought an impression was how many people viewed your website. Or better yet, can you explain to me.....I have 1965 impressions and 18 clicks? Does this mean the site was viewed 1965 times but the items clicked was only 18? Thank you. Very new here, as you can tell, but very eager to learn. Jean
