Anyone experience with Google News?

Hi,

I have three big authority websites, but i have some problems with Google News.

From the 3 sites, there are only 2 indexed by Google News. I've got a confirmation mail from Google about those; that these sites will be indexed in News.
Problem is: not every news item is indexed. Sometimes a week there is no item indexed in News, and sometimes a few items per day are indexed.

Other problem is that one site will not get through with Google News; it will not get indexed. I don't know why, i've submitted a Google News sitemap and did all the other things Google expect of me (Contact page, about us etc.).

Does somebody have experience with this?

Thanks!

Since you already have two sites on Google News, looks like you know what you do.

Anyway, give this a read maybe you can find some useful info: http://www.blackhatworld.com/blackhat-seo/white-hat-seo/601834-tut-how-get-into-google-news.html

Well, with those two sites which are already in Google News, not everything is working well. Some of the articles are indexed, not all.

Thanks, will read it!
