The Search Engine Algorithm Has Changed
Google Panda Update
Google search engines are trying to keep their search results as relevant and SPAM-free as possible. On the other hand, there are people who are trying to game the system or just take advantage of the existing loopholes. And, with the ever increasing number of websites on the Internet today, search engines are forced to tweak their search algos every once in a while to keep spammers at bay. For example, Google's latest big algorithm update known as Panda (or Farmer) was intended to do away with sites that provide poor-quality content and, as a result, provide poor user experience. However, it also affected groups of sites that have significant duplicate content by nature, such as e-commerce sites, online directories, etc.
