Google Releases Panda Update 21, Impacts 1.1% Of US Queries In English

Did you feel it yesterday? Some did, a slight shaking in the Google results. Yes, it was real. Google’s confirmed to us that a Panda Update happened yesterday.

Google said that worldwide, the update will impact about 0.4% of queries that a regular user might notice. For those searching in the United States in English, the percentage is higher. 1.1%, Google says.

This marks the 21st confirmed Panda Update by Google and stays in keeping with the roughly 4-6 week release schedule. Here are all the releases so far:

    Haven’t noticed anything here in the UK, but I did pick up on Google returning country specific subdomains or folders. Check out the blog I did on Facebook and MySpace results:

    Perhaps you could investigate this change on November 1st further?

  • Mark Scully

    Noticed a 10% drop of in traffic but difficult to attribute it to this or simply due to seasonal trends. I suspect if it was algorithm based, the fallout would have been worse than 10%.

  • Robert Wilkins

    I noticed that my site traffic has actually increased, not from the update but rather from my white hat SEO practices :) Here is my site:

  • Guest

    Noticed around 20% increase in traffic mostly from US.

  • Tesur Rajan

    Noticed around 20% increase in traffic mostly from US.

  • Tony

    Yup, I saw an increase in traffic. But I saw more of an increase on Friday morning. I suspect it to be a recovery from the Top Heavy update or maybe the disavow tool is starting to work from my giant Penguin drop.

  • Jason Nickel

    I’ve had a 20% uptick since the update.

  • Hugo Boarotto

    Google updates , can be very harmfull for some kind of sindication and back links , we must be prepared …….

  • Jaan Kanellis

    Never understood the constant tweaking of Panda and basically ignoring Penguin. I am sure they are not ignoring it, but maybe are having internal issues with the quality of Penguin?

  • MonopolizedSearch

    Does Google keep releasing these updates to stay in the news as to stay relevant? Or is this just another push by Google to monetize small businesses even further?

  • California SEO Pros

    I am in the boat with you Robert. My site got more hits in the past few days as well as. I just checked my clients and it seems almost all of them had normal or more traffic; I sure hope it is “white hat” practices too :)

  • Noi that Hoa Phat

    I realize that several keywords of my site ( were dropped after this update. A lot of work need to recover :(

  • Yousee

    No positive or negative impact this time….How necessary it is for Google to refresh the update after every month

  • Røcķíñğ Jåÿ

    If someone can let me know… what does new panda come with?

  • Nathaniel Bailey

    Do you not have analytics stats from past years? That would show you if its a seasonal trend, which you should really try to work out as best you can so you know whether or not you need to fix something that the Panda update didn’t like!

  • Nathaniel Bailey

    A boot up the backside for spammers!

  • Nathaniel Bailey

    At work we have noticed some good changes for a number of clients rankings, and seen some more spammy competitors (and spammy sites in general) moved off the first page which is great for work and searchers in general because google seem to have remove a good amount of rubbish this time around for us in the UK :)

  • Jon

    When did we start naming Panda updates as 20, 21, 22 instead of
    3.8, 3.9.1 etc.? Let’s pick a scheme and stick with it.

  • Rekha Bisht

    Once again Panda update! :( I found my few keywords dropped from their ranking. so this update affected my website. I is becoming harder to rank and to sustain the ranking.

  • Ajay Jhunjhunwala

    Oh again another update! i don’t understand why googel updating so frequently. The affected site percentage may look small but the original number is huge. Those affected can realize it. Google please do changes but after a decent interval.

  • Anurag Mishra

    yes 40% drop in traffic.

  • David Fisher

    According to the Google Twitter account, they had rolled out a ‘refresh.’ Is there a difference between a refresh and an update? To me, using that terminology seems to imply that they ran the algorithm on the SERPs without changing the algorithm’s signals. If a refresh is only that, Google re-running the same algo, that may help you narrow down a devaluation to changes you made to your site between ‘refreshes.’ Does any one know if there is a distinction?

  • Nick Stamoulis

    I agree with Nathanial. Go back as many years as you can and see if there was a similar drop in traffic around this time–that will tell you if seasonality is at play. Also keep track of any big marketing pushes (extra PR, newsletters, etc) that might drive a lot of extra traffic to your site initially and than taper off as your efforts ends.

  • Josh

    Looks good, now we just need to wait for the Penguin tool to see if these removed links actually do anything :)

  • Matt McGee
  • Yakezie

    Noticed 50% + MoM increase in traffic on Financial Samurai for 11/5,11/6, 11/7 so far today.

    Are we sure it’s not b/c of the elections and Hurricane Sandy electricity back on? Sam

  • Matt Barrie

    More likely to increase their ad revenue.

  • 1stchoicebpo

    What does Panda really do? I don’t understand really. I just notice my site has a PR2 from PR1

  • jacobstefen

    Gud luck.. Hope so it is not for few days….

  • Larry Kim

    nice avitar!

  • Larry Kim

    same here…


    All USA regionalized WP blogs just got a 15% increase yesterday. Usually traffic on our biggest money makers is going down this time of year.

    So I searched G to see if there’s was yet another algo update.

    Panda and Penguin have increased our traffic by over 100% to date. Blogs that we NEVER promoted – just wrote LOTS of content.


    Was wondering that two cause our sites do get al lot traffic from the eastern seaboard


    Confirmed SEO 2013 – Zero promotion and LONG detailed posts (2000-3000 words)

    Two years ago we started creating content that looks like a Wikipedia page – tons of internal links and extremely links – long form – detailed

    Don’t work on links ever now.

  • Durant Imboden

    Seems pretty simple to me: They’re continuing to refine and tweak Google Search, as they’ve been doing since the 1990s. (Also, Panda is less than two years old, so it’s early days yet for Panda in the overall scheme of things.)

  • Yakezie

    Financial Samurai is now up 100% week over week, and we’re talking 5 figure traffic figures a day. This 1.1% figure is a misnomer.

  • Durant Imboden

    Monthly updates do seem like a step backward, don’t they?

  • hometipster

    I noticed approximately 50% drop in traffic and yet all of our content is unique. We either write articles in-house or contributors submit them upon where we test the article against possible duplicated or scrapped content.

    I’ve been battling this for 2 years and I am beginning to wonder if this is really worth the hassle. Does anyone know of a site where you can test all content on the site for duplication in one go?

  • SEO Atlanta

    I had a ery legit, excellent, totally original site get HAMMERED in August and seems to banished to Penguin/Panda hell. Care to see the damage all these updates have done? Let me know and I’ll send you the URL.

  • Springboard SEO

    Is Panda “Flux” considered to be Panda 3.0, i.e., #8?

  • Brett Burridge

    I’m now DuckDuckGo’ing. Google are really losing the plot – just like Microsoft with that Windows 8 weirdness.

  • Dwivid Sharma

    Where we can know that what is actual update in algorithm and what it will gonna affect?
    I read your article regarding to updates but I like to know more about this updates. So any one help in this?

  • Brook Zimmatore

    So did I – 50% drop in traffic from November 6th onwards. Bastardos

  • Brook Zimmatore

    True, money maker sites are showing penalties. Random blogs we made are showing increase.

  • Michael Stricker

    Copyscape Plagiarism Checker – Duplicate Content Detection Software

  • hometipster

    Thanks Michael I’ll take a look. We do insist that our contributors do not copy or scrap content from other sites and we do check it before publishing – we also ask that the article is not placed on other websites. I will take a look at what you suggested.

    I’ve just finished going through the entire site, upgrading articles, removing all affiliate links, adding a rel nofollow to target sites under PR2 and a lot more. Hoping this will in some way help our rankings.

  • Buy Mailing List, Email List

    hahaha:) Yeah We’re so much frustrated with Google’s Updates. they’re doing updates without any relevant cause. anyway what’s the meaning of WAS in your terms>?

  • jacobstefen

    it means in upcoming days google will disappear and i’ll tell my grand son that there “WAS” a google search engine which i used to search cute cute names for him to call. :)

  • Ana

    I’m in Australia and although the update was the 5th Nov, I’ve seen the drastic drop in rankings a week after (13th). Could I attribute this to the update? Has anyone seen something like that?
