From the original article: "If you run a website, you know how important search engine rankings can be. Getting your site on the first page of Google can bring in advertising dollars, an influx of new customers, or widespread awareness of your cause.
However, there is much more to ranking high on Google than just optimizing your website for certain keywords. Social media can help (or hurt!) your placement – and the folks at TastyPlacement have done a little testing to see how much Google+, Facebook and Twitter really do affect search results."
