How does the AdSense API benefit your site and users?

By making it easy for publishers to sign up for AdSense and generate revenue, the API offers another compelling reason for publishers to choose your service over a competitor's--and remain loyal to you. The AdSense API is great for publishers who don't want the hassle of setting up their own accounts or dealing with cutting and pasting HTML snippets.

How does this generate revenue for you?

Approved AdSense API developers will receive a share of the revenue earned by the publishers you've signed up. In addition to the revenue share, you'll also receive $100 each time a new publisher you've signed up earns $100 in less than 180 days. This means that developers who currently charge for services can now use the AdSense API to offset some of the costs of your services--maybe even making it possible to offer your services free of charge.

Additionally, as the developer, you can optimize your ad's placement, color, and format to increase your users' earnings--and your users don't have to do any additional work to display optimized ads.

Websites already using the new AdSense API

RateItAll.com already published in a press release the new integration of the AdSense API in their service to Deliver Revenue Sharing to its Members. The program, called The RateItAll Economy, allows RateItAll members to earn cash for a variety of activities including using RateItAll’s Weblister tool to create and manage their own ratings list, adding a new listing to an existing ratings list, creating a profile with a photo, and referring new, contributing members to the community. Soon, the program will be expanded to allow participants to earn cash for writing reviews.

Where can you find more information ?

Currently there is nothing on the AdSense API blog, the only source of information is the AdSense API Home page in addition to the official AdSense Blog. The AdSense API Home offer a registration to be a developer, in addition to case studies and a great developer's guide where you can find all the necessary technical information about the AdSense SOAP API.

Just a note for PHP developers that AdSense API recommand NuSOAP Toolkit for PHP. I think they did a good choice, because nusoap is not only simple, but very complete and common SOAP implementation since many years.
