Google: We’re Unlikely To Confirm Current Or Future Panda Updates

What’s that, a Panda Update you just felt? Some believe so. But Google says it is unlikely to confirm that or any future Panda Update, as it has done in the past, because of the new “gradual” rollout infrastructure it is using for Panda Update changes.

Earlier this week at SMX West, Google’s Matt Cutts said a new Panda Update might hit this week, then later said that the update � and future updates � would no longer be apparent as an abrupt change. Rather, Panda changes would roll out over a series of days.

Because of this, Google now says it’s unlikely it will confirm officially if a Panda Update has hit. We were told from a Google spokesperson.

“I don’t expect us to tweet about or confirm current or future Panda updates because they’ll be incorporated into our indexing process and thus be more gradual.”

Until now, Google has confirmed all 24 Panda Updates that have happened, which were:

Panda Update 1, Feb. 24, 2011 (11.8% of queries; announced; English in US only)Panda Update 2, April 11, 2011 (2% of queries; announced; rolled out in English internationally)Panda Update 3, May 10, 2011 (no change given; confirmed, not announced)Panda Update 4, June 16, 2011 (no change given; confirmed, not announced)Panda Update 5, July 23, 2011 (no change given; confirmed, not announced)Panda Update 6, Aug. 12, 2011 (6-9% of queries in many non-English languages; announced)Panda Update 7, Sept. 28, 2011 (no change given; confirmed, not announced)Panda Update 8, Oct. 19, 2011 (about 2% of queries; belatedly confirmed)Panda Update 9, Nov. 18, 2011: (less than 1% of queries; announced)Panda Update 10, Jan. 18, 2012 (no change given; confirmed, not announced)Panda Update 11, Feb. 27, 2012 (no change given; announced)Panda Update 12, March 23, 2012 (about 1.6% of queries impacted; announced)Panda Update 13, April 19, 2012 (no change given; belatedly revealed)Panda Update 14, April 27, 2012: (no change given; confirmed; first update within days of another)Panda Update 15, June 9, 2012: (1% of queries; belatedly announced)Panda Update 16, June 25, 2012: (about 1% of queries; announced)Panda Update 17, July 24, 2012:(about 1% of queries; announced)Panda Update 18, Aug. 20, 2012: (about 1% of queries; belatedly announced)Panda Update 19, Sept. 18, 2012: (less than 0.7% of queries; announced)Panda Update 20, Sept. 27, 2012 (2.4% English queries, impacted, belatedly announcedPanda Update 21, Nov. 5, 2012 (1.1% of English-language queries in US; 0.4% worldwide; confirmed, not announced)Panda Update 22, Nov. 21, 2012 (0.8% of English queries were affected; confirmed, not announced)Panda Update 23, Dec. 21, 2012 (1.3% of English queries were affected; confirmed, announced)Panda Update 24, Jan. 22, 2013 (1.2% of English queries were affected; confirmed, announced)Panda Update 25, March 15, 2013 (confirmed as coming; not confirmed as having happened)

Going forward, we’ll have to make our own call if a Panda update has hit. We’re doing that with the last on the list, Panda Update 25, which we believe has hit.
