AdSense
Remember back when the Internet was young? Those were the days when most big companies were happy just to have their logo and phone number online. Making money on those site, it turned out, was another matter entirely and that’s where Adsense came into the picture.
AdSense serves up keyword based advertising across the Google empire and is a big triumph for micro-marketers. For publishers, AdSense offers new, and easy-to-grasp, revenue streams.
Throw in the fact that AdSense works on practically any Android powered app or mobile device, and you’re talking about one of the most successful advertising innovation in history.
