There are certain requirements...but it's very possible and not that hard to get accepted.
Here's a list of official Google requirements you'll need checked off before submitting your site to Google News.
In a nutshell, you'll need "10 authors" (think "pen names"), approximately 100 live articles, approximately 3-6 months of age and 1-2 new, fresh articles per day.
You'll also need a CMS that can meet their requirements. Although you can use Drupal or Joomla, I got curious and dug around to see what actual news sites were using. I found this very robust CMS called Vivvo that's already Google News compliant.
Now, Article Marketers....allow me to challenge your thinking:
Most article marketers are submitting their articles to EZA. They'll jam out 10-20 per day and make some cash. But there's a problem with this...you're building someone else's virtual real estate.
If EZA goes down...so do you.
If EZA rankings drop...so do yours.
What if you take 5 of those 10-20 original articles and submit them to your own news site using varous pen names. Simply use current events to spin new articles and publish. In 3-6 months, submit the site for inclusion on Google News.
Once accepted, you can monetize the hell out of the site. Want to put up CPA ads? Go ahead. Want to monetize with Adsense...no problem. From what I've researched, you can expect very significant traffic and revenue (Adsense=$100-$200 daily). And you can write about damn near anything. Ofcourse, keeping up with Hot Trends and making articles catchy will help your rise to the top.
Hell, the Vivvo software even allows paid memberships.
So existing article marketers can potentially go from 40 views per day to massive traffic. Or if you prefer numbers, 8000 visits for one article, in one day, for one keyword (source).
And no matter what happens, you're building your own virtual real estate that you can grow or sell with time. And as money rolls in, you can pay for unique articles/authors and focus on the management.
Think about it....
