Google's Head of Search Spam, Matt Cutts posted a funny video in which his body was cropped out to emphasize on the crux of the video. Matt said that although it is important to pay attention to the head of the document, it is also important to pay equal attention to the body of the document.
Head might have meta description, meta tags, but stuff in the body makes a big difference as. If the title tag and meta data do not match the content in the body of the page, it’s going to be difficult for Google to return that page to users. Matt said that a lot of people get caught up in description and meta keywords, but don't just think about the head, think about the body too, because the body matters as well. Matt's unique way of keeping his point is definitely going to help webmasters.Matt Cutts Crops His Body to Emphasize Importance of Body Content in a Document!,
