No, That Wasn't a Google Panda Update You Felt
Last Thursday, there were many webmasters and SEOs who felt Google had a major algorithm or index update. The update was thought to be the size of a major algorithm update such as when Google pushed out Panda, Penguin or any of those other major updates. A Google spokesperson told us there was no update that they were aware of. In fact, they told us there was definitely no Panda update and as far as they know, no other update that took place on or around Thursday, Dec. 13.
