We’re looking for AdSense publishers to test a new content syndication product. Our product allows you to enhance your website with related news stories while increasing your AdSense revenue. It’s free and there’s no obligation. It only takes a few minutes to install and you can remove at any time if it doesn’t work for you.
When a user clicks on a headline of an article, we display the entire article in a floating layer within your web page

Sites showing Google ads may not contain pop-ups or pop-unders that interfere with site navigation, change user preferences, or initiate downloads.
A site or third party cannot display our ads, search box, search results, or referral buttons as a result of the actions of any software application such as a toolbar.
Webpages containing AdSense code may not be loaded by any software that can trigger pop-ups, redirect users to unwanted websites, modify browser settings, or otherwise interfere with site navigation. It is your responsibility to ensure that no ad network or affiliate uses such methods to direct traffic to pages that contain your AdSense code.
No Google ad or Google search box may be displayed in a pop-up, pop-under, or in an email.
No Google ad may be placed on pages published specifically for the purpose of showing ads, whether or not the page content is relevant.
