In a test carried out yesterday, Google transformed its AdSense contextual advertising so that it's RSS compatible. This program allows the AdSense service for websites and blogs to behave as a Really Simple Syndication (RSS) standard.

According to the Google blog, "advertisers have their ads placed in the most appropriate feed articles; publishers are paid for their original content; readers see relevant advertising - and in the long run, more quality feeds to choose from".

Considering that this type of service is only at the beginning, Google published a list of possible usages of this advertising system. Google recommends editors to include the entire text of the articles, not just the title or the first paragraph and to place a single advertising message at the end of the text. Editors are paid a secret percentage of the income generated every time an advertising message is being accessed.

The 2.x RSSs allow Internet surfers to receive posted titles and online content crawled by services like Bloglines or My Yahoo.

A recent survey carried out by Forrester Research with the help of 60 commercial agents has pointed out that more than half of them are interested in the association with feeds. Google is not the only one that implemented this system, Yahoo and Kanoodle are also experimenting their own feed advertising solutions.
