About a day ago I discovered a fantastic Google service for who is a webmaster, or who administrates a small website like mine. I want to underline that mine is a personal website, not professional, talking a bit about me, my studies, my travels, my hobbies...visited by a friend and an occasional visitor! Well, last week it happened to me that I was browsing and by chance I''ve found myself in Google Adsense''s homepage (http://adsense.google.com), I subscribed and after 24 hours, they gave me permission to participate in the "operation". I will briefly explain what it consists of: the user, that is me, adds on a page of my website (maybe the most visited...) the advertisements that Google supplies to me. One can choose among a graphical banner more or less big, linked panels of various dimensions or rectangles with text advertisement. The service arranges to publish from time to time advertisements relevant to the page: if it is a page about music, there will be links to mp3 websites, an online radio, or dancing lessons etc... And now comes the most interesting thing: Google pays you on the basis of the clicks that your visitors do on its advertisements...on your pages! There are two options: advertisements directly published on your page - adsense for the content - or a Google search box published on the page that shows the results among which there are advert links - adsense for the search - (well, the usual search engine but embeded in your pages). Me at first didn''t believe it, but in 3 days I''ve already earned 5 dollars! Of course they are worth visitors'' clicks, they cannot click themselves automatically! The html code to paste in the pages is provided by Google and it is easily to publish... I hope that this short article is useful for who is like me, finds it convenient to earn an extra penny doing absolutely no effort!
