I think I saw one of your sites and they´re not very suitable for your adsense project.
In order for an adsense link to be clicked on they need to be useful for the visitor.
In order for adsense links to be useful to the visitor, he needs to be looking for something to buy (because most adsense links offer products or services).
In order to atract visitors that are looking for something to buy, you need to have the right type of website.
It all comes back to what type of website you have.
A product review site for example will be likely to have a decent CTR to obtain your goal. But if your offer exactly what the visitor is looking for he has no reason to click on adsense and he won't,.... no matter how much you throw the ads in his face.
And unforntunately for you, those types of sites require a lot of work,.
