It’s important to remember that some of the biggest changes in Google search results were not named all named after animals. As a matter of fact, some major changes in Google search algorithms this year have been named after nothing at all. When analyzing Google’s pervasive search quality highlight posts on its official Inside Search blog, algorithmic tweaks for Panda and Penguin represent less than 3 percent of the changes Google has made to its core search functionality since the first of the year.
In order to be able to make these kinds of statements, I had to analyze all of Google’s Inside Search blog posts made since the first of the year, which includes updates actually made in December 2011, and try to classify the Google product, service, or function that was attuned. You can read my analysis of Google Search Updates over at Search Engine Watch, but I do plan on updating additional details here in a future post.
