It started with a release in the U.S. in February, followed by an international release to English language users in April. Today Google announced that the “Panda” update is launching internationally in all languages, with the exception of Chinese, Japanese, and Korean, where they are still testing improvements.
When Panda launched it affected almost 12% of English queries significantly enough to be noticed. For most other languages the change will impact 6-9%. This most recent launch also includes some minor changes to the English version.
The objective of the Panda algorithm update is to help in cleaning low-quality sites out of search results and improve rankings of high-quality sites. This focus aligns with Google’s goal of giving users the most relevant answers to their search queries and to do it as quickly as they can.
