Why AdSense is better than others?

We all blogger or website owner know that Google AdSense is better than any other contextual or non contextual advertising network. And all common people are also believe in that. Google AdSense will give you much higher amount for a particular traffic activities comparing any other network.
That is why people are so eager to get this. Now the question is, how AdSense gives you higher revenue than other network?

AdSense shared a particular percentage of revenue to their publishers, which they collected from advertisers. Like-  68% publisher revenue share for AdSense for content, 51 publisher revenue share for AdSense for Search. But you can see in many other ad network that they are sharing much higher revenue than AdSense. Here you will be mislead if you think about revenue share alone. 

Suppose you are a publisher of AdSense for content so, here you will receive 68% revenue shear from AdSense. That means if Google ads on your site collect $100 from advertisers, then you will receive $68. AdSense ads are generated from Google AdWord. As maximum advertiser are using Google AdWord for online advertising so, generally Google is collecting much higher revenue from advertisers. But other advertising networks are unable to collect more revenue from their advertisers like Google. So, here you will receive poor revenue even they offering 80% or 90% revenue share. 

That is why AdSense is the best, even other network offering much higher revenue share.
