There’s talk going around of a “Panda 3.0” or a “Panda 2.1” in reference to recent tweaks to the Google algorithm. The fact is that Google makes many adjustments to its algorithm on an ongoing basis, and generally only feels the need to officially comment on the really big ones.

Don’t expect guidance from the company every time it makes a tweak. It’s actually somewhat surprising they’ve discussed the Panda update as much as they have.

On May 6, Google Fellow Amit Singhal wrote in a post on the Google Webmaster Central blog, “Some publishers have fixated on our prior Panda algorithm change, but Panda was just one of roughly 500 search improvements we expect to roll out to search this year. In fact, since we launched Panda, we’ve rolled out over a dozen additional tweaks to our ranking algorithms, and some sites have incorrectly assumed that changes in their rankings were related to Panda. Search is a complicated and evolving art and science, so rather than focusing on specific algorithmic tweaks, we encourage you to focus on delivering the best possible experience for users.”

Search Engine Land Editor-in-Chief Danny Sullivan says, “Google won’t release the percentage of queries impacted but says this is far less than in the other updates. Changes were made in the past few days.”

In other words, not every tweak Google makes needs a name. Nor should every tweak since Panda be considered part of the Panda update.

“We’re continuing to work on additional algorithmic iterations to help webmasters operating high-quality sites get more traffic from search,” said Singhal. “As you continue to improve your sites, rather than focusing on one particular algorithmic tweak, we encourage you to ask yourself the same sorts of questions we ask when looking at the big picture.”

Those would be the questions we looked at here.
