I have some experience with adsense, but not a lot. The price of every click on your page advertice depend on various factors.
Google measures the importance and relevance of your page. For example, some of this factors are: your page's pagerank (inbound links), how old is your page (old pages are more important than recently created), the trafic (how many visits it has) , good desing, always online, etc.
With all this factors the price of an ad impresion costs more or less. If your page it's relevant for Google, they will pay you more than if your site it's a not a relevant one.
Other important factor is the subject of your website. In a site specialized in a concrete subject, for example, gadgets, the possibility that the click over a technology advertice becomes a sale is greater that if your site it's about garden and plants, so the price that Google will pay you its higer. If your content its personal, general or you mix a lot of diferent things, the sale will be less probably, so the click will be a low price one.
Also influences the popularity of the keywords that the advertice is about. The advertisers bid up to place their publicity in the best sites (with the program adwords of Google). There are very spensive words, like health or finances, and others are cheaper.
Another important factor is the CTR (click-through rate). CTR is the ratio of the number of times a user clicks on an online advertisement per number of viewers who view the Web site that has the advertisement on it. For example, if one out of 100 people who visit a specific Web site click on an advertisement and are taken to the advertiser's site, then the CTR of that advertisement is 1/100, or 1%. At the most high it is the CTR, greater will be the price of click.
Maybe in your case, sometimes Google adsense have no advertisers to show in your page, and show ads of public interest, that they are free, no pay fore them. So you can have a few clicks but 0.00 earnings.
Itīs important that you don't click over your own ads, Google will ban you and the clicks wont count (I think this).
So be patient, construct a page with good content and put the ads in a right place, and you will see how you CPC grows up.
