Google Pushes Out 2nd Panda Refresh of Month, Surveys Users on Search Result Quality

A June 25 tweet from the official Google account on Twitter announced the release of Panda 3.8, a data refresh they said noticeably affects less than 1 percent of queries worldwide.


In their tweet, Google referred people back to their May 2011 post, “More guidance on building high-quality sites“, to offer context for those unfamiliar with Panda.

The June 25 data refresh was Google’s second Panda update this month. Google also announced via Twitter (on June 11) that a data refresh had begun rolling out the previous Friday, June 8. That one was said to affect less than 1 percent of U.S. queries and 1 percent worldwide.


A data refresh doesn’t change the algorithm or signals; it does just as the name suggests and refreshes the data within the existing algorithm. Data refreshes typically affect fewer queries than algorithm updates.


Meanwhile, Google is also asking users how satisfied they are with their search results. Internet strategist Nathan Sauser posted the above screenshot of a Google pop-up on the search results page that asks searchers to rate their level of satisfaction with search results – ranging from “very satisfied” to “very dissatisfied”.

Google has been using human quality raters for some time to evaluate and troubleshoot the algorithm by rating search results. This is the first time we’ve seen a live experiment, using seemingly random users, to submit their feedback on search quality directly from the SERPs.
