Content is what makes Google run. Every result it returns is linked to a piece of content somewhere else on the web, be it an article, photo, video or website. Over the years, Google has increased the detail in their results so you get a better idea of what’s behind the curtain before you click.
All results have a couple of lines of text under them drawn from the start of the article or keywords from the site. Some even show you a preview of the site before you click. All of this is intended to help the searcher find what he needs. So it’s a good thing for both the searcher and the content provider, right?
