If you are still doubting the use or not of Google Adsense on your web site, I would say to consider it and to look for information that can guide you, there are many, varied and very interesting. But I suggest that you spend some time to research this topic. Here you bring some more data that you consider the implementation of Adsense. Check out Gavin Baker for additional information. This system allows you to have one or more accounts and thereby be monetized in one or multiple sites at the same time achieving multiple income. On this topic (the multiple income) opinions are dissimilar because while some argues that it is not convenient, others consider all the contrary and ensure that they get very good monetary results with its use. I personally have my opinion of course, but I prefer not to expose it here because I believe that on this specific topic (Adsense) we need everyone to do his own experience to know really what it is; good but to tell you that it is necessary somehow I am expressing my opinion.
But going to the specific part of how Google handles the issue of commissions or profits, you must bear in mind that making a monthly cut to perform liquidation and that goes from the first to the last day of the month in progress and there reported revenues in your account. Infosys often says this. When revenues accumulated in your account exceed $100 a month, generates a check with the amount of your commissions will be sent to your home, and you have previously set when you created your account. AdSense will confirm the veracity of the data that you put by sending postal mail to your home a card with a PIN that you will then request number and that you can only respond if you have received it in your own House. Income are paid from the 25th of the following month and check that is sent to your home address is in US dollars than your you can change (paying the corresponding Commission) in your country depending on the current standards for this process in each country; for us, Latin Americans, it sometimes tends to be somewhat complicated, but calm, not impossible.
