how can i know which ad is clicked and from wich country

i used analytics and adsense to know which ads is clicked and from which country , but i couldn't know that

also i don't know what is the use of adsense channels and how i use it

 

adsense channel report shows yuo which ads were clicked. regarding from which country, that data is not available for each click but you can use analytics to see your visitor geo

 

you will not be able to know this , use a counter like statcounter for this

 

use Google analytics to find out where your traffic is coming from, that is what i do.

 

You can not know which adsense is clicked from where.
But by Channel, you can monitor
Which Ads is performing well
Which text or banner is doing well
Which place on site is giving more click.. etc.
