AdSenseis a Google service for which the webmaster inserts a website text-based ads, called AdWords, and get a lot of money for each 'click' that visitors click on the ad.
Operation is very simple. The webmaster inserts a JavaScript code that calls a Google server. This server analyzes the page where you insert the code and, depending on the contents therein, generates a code that displays a series of ads for companies that are related to the theme of the page.
In this way, you get the 'clickthrough rate' (the percentage of visitors who click the link) is higher, since readers are more interested in the topic. Thus, the benefits are greater for the webmaster.
Moreover, the formats of the ads are highly customizable, both in color and size. Even you can prevent ads from your competitors web sites appearing in this advertisement posted.
What I need to participate in the service Adsense?: Only need to be the administrator of a website and make a request to the Google team. That yes, Google has some very clear rules with the quality of the websites, not to insert AdSense on pages that have pop-ups or dialers, for example.
Once your site has been accepted, you can start inserting advertising in minutes. However, it may be that the ads are not visible for a few hours since the Google ad server have to crawl your site.
Google does not provide any amount of money for each 'click', varies with each advertiser, and it is Google that decides this amount. However, in every moment you can see how much money you're winning.
Google sends a check to your home at the end of each month provided you earn more than $ 100. Anyway, the end of each year sends you a check for whatever amount of money you'd be.
Of course. Check out this article in which Google announced the start of the AdSense program in Spanish, Arabic or another language.
