Does google pay to publisher on the basis of count of impresstion of an ad?

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.

 

Thank you very much for your reply.

 

I prefer text for google since it work well for me. you can try it

 

Text, but really adsense is so hard to get running buddy, hope it goes well!

 

yes, generally we can say yes, only when someone clicks on an ad do you get paid.

 

Sometimes you can get paid by impression but more often than not its by 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
