One Of The Most Frequently Asked Questions Seems To Be.......

Why do I have clicks but no earnings?

The most basic answer to this is that if you are getting clicks but no earnings then that means that Adsense is counting those clicks as invalid!

Another, more remote, possibility is that the ads that have been clicked are public service ads of which you don't get paid for.

One of the main reasons why public service ads may be appearing on your site is that the adsense spiders can't find any content on your site that would appeal to advertisers.
