Google News is an extremely powerful way to drive traffic to your site, if it is worthy to be included in Google News. Google Finance is another avenue to drive traffic to your site, but how do you get Google to list your articles in the news or blog area of Google Finance?
A Google News Help thread discusses just that. In fact, Inbal from the Google News team explained how to be included. She said that you need to include the full ticker name, prefixed by the name of its stock exchange. So in Google's case, you need to include (NASDAQ:GOOG) in the article. I think it might also help to include that ticker in the title, but we can test it out on this article and see how well it does in the NASDAQ:GOOG listing in Google Finance.
A comma-separated list of stock tickers of the companies, mutual funds, or other financial entities that are the main subject of the article. Each ticker must be prefixed by the name of its stock exchange, and must match its entry in Google Finance; for example, "NASDAQ:AMAT" (but not "NASD:AMAT"), or "BOM:500325" (but not "BOM:RIL").
Clearly, you don't want to abuse this and be removed from Google News and/or Google Finance. If you want more advice in Google News inclusion see that article, keep in mind, the rules may have changed. They also have a publisher FAQ and described how they rank articles.
Forum discussion at Google News Help.
Update: Several minutes after posting this story, I checked Google Finance for the GOOG ticker and guess what I saw?
Clearly, if you write a lot about business related topics that impact stock price, make sure to use this tip when your article is relevant to that company.
