Google AdSense is a fast and easy way for website publishers of all sizes to display relevant Google ads on their website’s content pages and earn money.
Because the ads are related to what your visitors are looking for on your site — or matched to the characteristics and interests of the visitors your content attracts — you’ll finally have a way to both monetise and enhance your content pages.
It’s also a way for website publishers to provide Google web and site search to their visitors, and to earn money by displaying Google ads on the search results pages.
Google AdSense is a pay per click program that you implement on your website with the addition of some HTML code. If you have a high traffic site, you can make some serious dollars by Google advertising on your website. A word of caution though, Google AdSense will display advertisements based on the content of your page, so there are many cases where your competitors website URL will display.
