Impressions is the number of times any URL from your site appeared in search results viewed by a user, not including paid Google Ads search impressions.

Click-through rate (CTR) is an incredibly important concept in search engine marketing. The simplest definition is that click-through rate is the percentage of people who click on your ad after seeing your ad.
