If you write a press release or story about your website. You can submit it to http://www.jazzou.com which is an internet news and SEO based website. If you are in that niche or nearby you can get backlinks and a flood of traffic back to your website because stories submitted to Jazzou are automatically put in Google News giving instant results. Most sites charge for this. Currently you can join free and insert links too http://www.jazzou.com
There's actually plenty of Press Release publishing sites, both free or paid, that submit your story to Google News. It's best to always submit your PR to a few of those, and for even better results vary the headline and the content a bit. Ones that I've had most success with have been 1888pressrelease, PRLog (both free) and businesswire (paid).
Its a directory with a news feature also. People can join and submit news and also list there website. The news helps the directory gives more exposure to the site etc
I have registered in mentioned website...but how much times it takes to include my url to google news.
