For the past few months, we've reported a lot of Google SERP changes in our blog Even the WebmasterWorld Community is keeping a close watch on the action all this while.
Till now there was no record of the exact changes that were made by Google, but recently WebmasterWorld came out with this list of archives that is geared up with an update of WebmasterWorld Google SERP changes posts.
Thanks to Tedster who is responsible for sharing it with all of us! The list of changes are from December 2006 and has continued pretty tremendously through today. So all you people out there, who are interested in having a look at Google's past history, there is no perfect way than checking out this list once and feel a little nostalgic as well!
Forum discussion continues at WebmasterWorld.
