hubpages, I have an account on hubpages, and set up my Adsense ID in my hubpages profile along with Kontera, Amazon and eBay. I tried to sign up an account with squidoo, and started to create a lens, but I couldn't find anywhere to insert my Adsense ID.
And I found out that actually you couldn't use your Adsense ID on squidoo! Squidoo uses theirs and then when the ads are clicked on your lenses, you get your share from squidoo.
Adsense revenue is calculated like this: All revenue is dropped in one big pool. 45% is subtracted for Squidoo operations, 5% goes to Squidoo charity. That leaves 50% in the pool for lensmasters (owners of lenses). That pool is then divided according to an algorithm.
This is quite funny, and you will find more on this if earning loyalty is your main concern.
And if you haven't got your own Adsense account or for some reasons banned by Google, it's a good way to publish and earn through Squidoo.
