A WebmasterWorld thread asks, what is the incentive to lure visitors off your web site and into Google News? One publisher said, "if a widget is going to take visitors away from my site, it certainly better compensate me for them!"
I spent the past fifteen minutes looking for an old feature that Google AdSense had available but discontinued years ago. It basically was a widget you can add to your site that would show news, web results and other content from Google, but it wouldn't earn you money. They discontinued it, but I cannot find my post that talks about it, at least not now.
Here is an example of this Google News Widget in action:
But some publishers say that this added content makes for a better quality site.
I actually have two sites where I plan to add it as a service to my regular members. I don't really care if they leave my site, what I care about is that they keep coming back. The more useful the site, the more likely they are to come back.
