AdSense is just one of several income streams your business can produce.
AdSense primes your monetization pump like no other option...
* It's low maintenance -- no products to ship, no customer transactions to deal with,
etc. Google provides the ads and the guidance on how to easily insert them on your
site.
* Forget banners. Google outperforms them. Contextual ads rule!
* Ad networks? Not worth the bother.
* Blend in a few well-chosen affiliate programs and it's passive income at its best!
You provide the relevant "real" content and AdSense compensates your efforts.
