Dear Friend:AdSense is Google's program which allows you to sell space on your website to host other people's advertisements. Hosting AdSense ads on your website or blog is completely 100% free to you as the host and a great way to earn some money. How do you earn money with Google's AdSense? Simple, every time someone clicks on an AdSense ad on your blog Google pays you. Someone clicking on your ad is called "click through." Your visitor is clicking through your webpage to another webpage via the AdSense link on your website. Google pays you for these click through visitors because their advertising has successfully reached a visitor on your blog. You get paid because you agreed to host the ads and you provided good content which got a targeted ad and a resulting click on that ad.AdSense is a very popular way to monetize a blog because it is simple to set-up and use, especially on a blog which is hosted by Blogger. Why? The answer to that is simple; Google owns both Blogger and AdSense so the two have been programmed to work very well together. I have written a book called "Blog Monetization". It contains everything you need to know about making money with your blog. It covers every aspect you should know... from the rules of adsense, how much money you can make, finding forums of interest, backlinks information, article submissions, press release submissions, search engine optimization, SEO & marketing your blog and everything else you need to learn to have a successful blog.
