It is not hard, but is not easy too!

I started with Google AdSense on 9 of November. Today is 25 of November and until today I earned $16.30.
I am blogging more than 6 months and in this period I build substantial public on my blog. This blog do not have an option to support a AdSense, so I switch to blogger.com. Now I am writing the whole text on www.blogger.com, and only the first few sentences of the text on that old blog of mine. So everybody who like to read the whole text need to come to read on my blog on blogger.com.
This strategy show that in no time everybody can build a traffic only if is working hard.
Also when I post a comment on other blogs, I copy paste the URL of the text which I thing that will be interesting for them.
Usually I have 100-150 visitors per day.
Number of visitors are essential and for bigger number the content is very important. So if you like to earn with AdSense it is better if you have to tell something.
