I do apologize for that awful pun, but the Google Panda update has caused a huge stir in the SEO world. Google updates their algorithm all the time, but every once in a while they have a big update that completely changes the game. Google Panda was a massive update by Google to their search engine to limit content scrapers (people who steal content and host it on their own sites in the hopes of getting revenue from ads). Many legit sites saw a major drop in traffic and ranking, and Panda has changed (drastically even) the way SEO works. The latest update is starting to clear the fog, and Google has been explaining their reasoning behind the Panda Update.
