Variation in money per clicks ...

Firstly apologies if there's already a thread for this question but i was just wondering how Google come to the figures per click. Im very new to adsense so sorry if there's a simple answer for this.

For example:

The other day i had 4 clicks and got $4.09, yet yesterday i got 4 clicks again but only got $0.28 - Why is there such a big difference in the amount paid per click?

Regards

 

Google Pay you the half of what advertiser pay, so if the advertiser pay $0.1 per click, you will get $0.05 , if he pay $2 per click, you will get $1 ,
So I think that the other day, you had a high paid ads, but now very low paid ads. You will get more amount paid per click when an advertiser will pay more for the keywords your website is based on.

 

Be happy that you do get high paid ads.. if your site was rated in a lower quality range you would be seeing nothing but those lower paying ads.

Keep up the good work!

 

The 1:1 ratio for CPC is a very good result... You must be thankful to adsense..

 

oh dont get me wrong, it is certainly nice to get that amount for them, i was just wondering why there was such a wide variation in amounts

thanks for all your replies
