I am new to Google Adword and Adsense. I want to know if Google pay for ad impression or not? OR, Does Google only pay when a user click on the ad?
Google pays for click and impressions also. For banner, it pays impressions, and for text ads, it pay for click.
When someone clicks on your ads, you get paid... You won't earn even if you get a million impressions unless somebody clicks on an ad xD
