Google Adsense is a successful advertising program from Google. It enables website owners to show relevant ads on their website. The Adsense network is a Pay Per Click (PPC) network. Pay per click is a popular way to advertise on the Internet. Someone clicks on a banner or ad on your website and you earn an amount of money for it, which could go from a few cents to several dollars.
Google launched Adsense in 2003. From that moment on, it was possible for owners of both large and small websites to serve ads on the Google advertising network to display to their visitors. Advertisers can create ads using the Google Adwords program from Google. These ads will be displayed on Google sites, like the Google search engine, and on websites that are affiliated to the Google Adsense Network.
Both image and text ads are available in the Google Adsense Network. You can choose from a wide variety of formats, going from the standard 468 x 60 and 234 x 60 banners to Skyscrapers (120x600), Squares (250x250 or 300x250) or Leader boards (728x90). As a website owner you have a lot of control over the ads that are showing on your website. You can for instance change the color of the text, links and background of your ads. Most webmasters experiment with the colors, sizes and places of the ads to find out which ones work best for their websites. The ads showing should be relevant to the content on your page. Google's analysis of the content is not infallible, so it can happen that sometimes irrelevant ads show on your site.
Including an ad on a page is very simple. On your Google Adsense page, you will be taken step by step through the process and ultimately you get a HTML-code that you need to copy and paste on your webpage.
The Adsense ads may only be placed on pages that comply with the program policies of Google Adsense. Make sure you read the Adsense conditions before you start with the Google Adsense program.
In your Google Adsense Network you can use so-called channels. With these channels you can monitor the results of specific ad units and pages, to get valuable information on which ads are effective and which ones are not.
Google uses automatic as well as manual analysis on sites in the Adsense network to check on click fraud, for instance when many clicks on ads come from the same IP address. As soon as click fraud is detected by Google, the publisher in the Adsense program gets expelled and loses as well his outstanding revenue.
