Adsense is one of the quickest ways to get your website making money, it turns an area of your site which is worthless into a money making area of virtual real estate. You can end up marketing your website so it becomes a high traffic site, but not earning from it.

You can also add it temporary to areas of your site that are still work in progress, bring in some money before you’ve completed that project.

Some marketers build sites full of good content just to earn off of Adsense, as long as the content is unique, then this will work.
