Google Panda Update – A Grizzly in the SERPs

By Apr.21, 2011

What is the Google Panda Update? How has it affected the SERPs? Which tactics might be taken to minimise the effects of the Google Panda Update?

The recent Panda, or ‘Farmer’, update to the Google search engine algorithm has had some interesting and unexpected results in the Search Engines Results Pages (SERPS). Working for the Search team at the Manchester digital media agency Fast Web Media, it is vital for me to understand the purpose, initial impact and long term implications of the Google Panda update and shape SEO strategy for our clients accordingly. Considering all that I’ve learnt on the SSMM course at Salford, I thought I’d tackle this Panda head-on.

The purpose of Panda?

The Panda first reared its head in February 2011 in the US, whilst the rest of the world watched and waited for Panda paw prints to appear in the rankings. Sites in the UK that received significant traffic from the US quickly saw if the Panda update would affect them once it was rolled out globally in March.

The Google Panda update had one principle aim:

Reduce SERP rankings for Low Quality Sites—i.e. sites with low value to users, generally containing unoriginal or shallow content.

The intended targets in the Panda’s sights? Low-quality domains which had little user trust and contributed trivial levels of information or services, such as, affiliate sites containing a high volume of content scraped from legitimate sites. As expected, such sites lost significant visibility in the US Google-SERPs at the end of February.  But what else was hit? This would apparently affect the results of some 12% of search queries. An independent SEO software firm, Sistrix, collated a lot of data and published a list of some of the winners and losers from the update (although the recent article from State of Search questions these figures and their severity)

The main losers appear to be:

  • Price comparison sites, such as travel sites
  • review sites, like
  • voucher sites,

You can see a more recent list of those affected on Pete Young’s blog (of SSMM fame!) On first look, what is similar about these sites? Shallow content? Poor structure? Prolific use of ads? Poor content and aggressive ad placement generally results in poor user engagement – you are unlikely to stay on a site for long if it’s full of inane drivel and haranguing you with pop-ups.

Google’s algorithm has previously proven capable of identifying nonsensical spam (e.g keyword stuffing) but Panda’s mission is to identify shallow-content, low quality sites. A supposed by-product of the Panda update was that it would help Google to identify high quality sites and reward them in the SERPs accordingly. Sites such as those belonging to established brands, which have their own original content, and ones which promoted high value user experiences would win over the heavily optimised affiliate site that allowed for no quality user engagement. This very interesting interview by Wired with Google engineers Matt Cutts and Amit Singhal in March 2011 outlines the Google thought process behind the update.

Bamboo-zled by the Panda

Some in the Search industry feel that the Panda update was a long time coming and that “wise” SEO practices will have protected against algorithmic changes that targeted low-quality content. The side effects of this ambitious update have been quite a lot of collateral damage. It has hit legitimate sites with a lot of user-generated content, such as Review Centre (see their concerned reaction to the Panda update in a blog post on the Review Centre website).

Mahalo, an information sharing site with a large and active community, suffered heavily from the Panda update and 10% of Mahalo staff were apparently fired the day after the new algorithm took effect. Mahalo is widely viewed as a content farm and is exactly the kind of site Panda should be targeting. This interesting article about Mahalo by SEOBook discusses it in more detail: SEOBook: Black Hat SEO Case Study Nevertheless, traffic being heavily cut through these changes is a grave issue for many sites and businesses, big and small. And more recently, questions have been raised as to the possibility of competitive targeting of certain Microsoft owned sites by the algorithm changes.

Saying all that, there are many ecommerce affiliates that are still holding strong positions and all their product descriptions are duplicated. I know at Fast Web Media, we can still see 2 or 3 voucher sites ranking within the top 10 for brand specific keyword searches for a particular client. Google have removed the ability for webmasters to ask for reconsiderations for those who’ve suffered from the affects of algorithm changes but you can tell them if you think you’ve been unfairly dismissed.

What can we learn from sites like Mahalo which hold some genuine value being penalised by the algorithm? Mahalo’s content base is vast and in topics so broad that it is suspiciously vague in its purpose. It’s certainly no Hitchers Guide to the Galaxy. And what of voucher sites? They often contain many broken links, timed out deals, etc. Is it this kind of sites Google is to rid the SERPs of? It is interesting to note what happened to the price comparison site,, which was also negatively affected by the Panda update. Google bought that site last month for £37million. Why would Googly punish its own acquisition, other than to appear fair in its execution of its algorithm? Is it that valuable for Google in terms of a business for price comparison or is it a knowledge/data gathering exercise? It is likely that Google are investing in comparison websites as a way of gathering information about how people interact and use such sites. Under the current Panda update, the way content is produced, structured and shared across such sites is too subtle for the algorithm to distinguish between those more low-quality sites. This first generation Panda, although quite unruly, may evolve to be something a bit more personable and sophisticated when recognising quality content in successive incarnations.

Paws for Thought

So, what do you do if have been backhanded (or “backpawed”) by the Panda? Combating Panda at a basic level boils down to examining the structure and content of your site and being sure to eliminate duplicate or shoddy content. You can start by looking at the impact on traffic and user behaviour using Google Analytics across the different pages of the site and go from there. SEO Mark Nunney clearly outlines some more detailed steps to analyse any potential impact and steps to rectify a SERP slashing in his Panda mauling survival guide. In summary, the main things to look out for are:


  • A high level of duplicate and unoriginal content – either internally or from content being very similar to other site. Example site: Tech blogs – gadget reviews, etc.
  • Overzealous On-Site Optimisation – Poorly written content for the user – lacking semantics – continuous repetition of the same phrase or keyword.
  • Many pages throughout the site with a low amount of original content.


  • Low CTR (click through rate) from SERPs
  • High bounce rates and very low user times on the site
  • Low percentage of returning traffic to the site


  • Lots of sponsored ads – especially irrelevant ones – littering the page
  • High number of paid links from sites owned by the same brand/company/site owner for self promotion
  • None or an unconvincing Social Media presence, nor little mention from sites like as news, reviews, forums.

These are all classic SEO issues which should be addressed when implementing best practice and have been covered extensively on this SSMM course at Salford. And although we can outline what quantifies a quality user experience (high traffic, high returning traffic, low bounce rate, long amount of time spent on site, etc), just how does Google begin to identify what is “quality content”  algorithmically? How can the web crawlers scan the content on sites and obtain a substantive and accurate impression of the semantic value of that page? The easiest signals to look out for if content is quality is the amount that site is shared – linked to, tweeted, social bookmarked, etc. AKA The capital of social engagement!

The issue is that “quality of content” is a highly subjective matter. How does one define “low-quality content”? The Wired interview with Cutts and Singh mentions that they compared the Panda results using the Chrome Site Blocker (allowing users to specify sites they wanted blocked from their search results) as a case study for what qualified as “low quality content”. The intuition of the algorithm can only be so sophisticated.

“The Panda eats shoots and leaves; it doesn’t go on Masterchef!”.

Google try and collect enough information and data on user behaviour to create and apply an objective algorithm to subjective matter.

Keeping this in mind, this is where I wonder if the Panda update is a pre-emptive move before rolling out Google +1

The Personable Panda

Google has also been trying to jump on the social bandwagon of late without much success. Sites such as Google Buzz, a social messaging and information sharing site, and Google Knol, similar to Quora, have failed to crack into the social media market with any noticeable effect. Back in 2009, Google introduced Google Social Search and it has updated and improved the service constantly since then. Matt Cutts not long ago revealed that Google would start taking into account social impact of URLs in the algorithm – i.e. the more a URL is tweeted and shared on Facebook, the more gravitas that link will be given in the eyes on Google. As a result, SEO now involved more than just on-site optimisation and PPC. Social media is now the dominant force in the way internet users share and consume content, and it is playing an increasingly significant role in determining where your site appears in SERPs.

This latest update is a significant shift in the way social affects a site’s position in the SERP. Whether users are posting videos to YouTube, publishing photographs on Flickr, writing content on their blogs or just talking to their friends on Facebook and Twitter, their activity now affects a site’s authority and how it is viewed by Google.

So called “Google +1” is being trailed in American and you can beta test it on your own account at the moment in the UK. It is a way of competing with social networks, such as Facebook, but whilst also being able to glean from user behaviour what results far more relevant quickly and effectively. What is Google +1? Google will allow you to click on a +1 button next to a link as a seal of approval. And other users in your social network groups will be able to see that you’ve “+1” a link.


You can read more about Google +1 from Techcrunch and the speculations on its uses but the reason I’ve included it in this post is in the Panda update preceding Google +1. By currently being largely closed off from the social media world, Google lacks the ability to be able to analyse user behaviour on a highly social level. This is where Google +1 could act as a key to unlocking some of the data potential whilst apparently bettering the user experience of the search engine.

Allow me to elaborate: Panda has apparently hit the tech blogging community quite hard. Many of these sites are genuine hubs of collective interest. But as pointed out by Patrick Altoft in his blogstorm post, how many times do you need to hear about the same gadget review? For such forums and blogging communities, the significant drop in traffic could drastically reduce their site’s viability. Thinking long term, I wonder if such updates that negatively affect the visibility of said communities may further catalyse the way that people will interact online – less through many review sites and forums and more through social media.

Much like if someone dictated you what you could and couldn’t do at a party, you’ll probably just sit sulking in a corner or end up not even going. The Panda update is more evidence of a paradigm shift in the way that content is structured and angled more towards enabling social online. With this in mind, I was wondering if the Panda update may be pre-emptive strike that encourages websites to structure themselves favourable, ready for Google +1.


Google wants to be more than just a search engine – and its forays into all sorts of projects, most particularly with social projects such as “Buzz” and “Knol” are testament to that. Google talks about wanting to produce the best user experience possible. Why? So users continue using their services. Yet I am curious about the long term impact on social communities, such as legitimate tech forums, which have been hit by the Google algorithm by such changes. Many of the Panda victims appear to make sense, and with any algorithm change there are winners and losers. But why remove the visibility of sites that allow and foster genuine community engagement? At the end of the day, the algorithm is a scientific formula that is being applied to millions and millions of sites. It is inevitable that some genuine sites, in particular ones which do have a lot of the same content (even if it is user generated) will be hit by the update.

Under the new Panda regime, what do you do if you search for something and forums/review sites don’t show up in the top 10? You search again, you use other sites. Users navigate the SERPs more and giving Google more user behaviour data. Users may also be more inclined to use Google reviews, thus helping to promote Universal Search, etc. By hitting the review sites, I wonder if it’s not just Google trying to promote their services and in turn getting more information out of its customers. Is Panda preparing us to be more social (along with the advent of +1) by clearing the SERPs of site that had poor user engagement?

As we all well know, you cannot force online communities to be social – social sharing and communities and manifests themselves in a way that external forces can try to influence but it is often an internal catalyst which drives it and helps it take form. You can create a social space but cannot really dictate the way it is used – trying to do so often spells disaster. But social is well and truly here in the SERPs. And it will be interesting to see how the SEO community shifts and adapts strategy in the coming months post-Panda.

    Top article that Briony! Very comprehensive. Love the animation, was that from a cheese advert? Remember seeing them on Youtube.

  2. gices says:

    Punishing the whole site for the thin content is just wrong. There are many sites which have high quality content but contain some shallow content as well. Panda should devalue the thin content pages rather than the whole site.

  3. Briony says:

    Thanks, Colin! Yes, the animation is from an odd video for some cheese called Panda. Couldn’t resist popping it in!
    Gices – I wonder where you draw the line regarding “thin content”. How many pages of thin content would be acceptable before a quality site is penalised?

  4. Rupert says:

    Really like the conclusion point about Google trying to push their own services through Panda. Hadn’t considered that and it makes a lot of sense. Great post!

  5. I second you Gices, there are lots of contents in article directories like ezine, hubpages which has valuable articles for the readers however, some of them are obviously shallow. There is no point to devaluing the entire site, rather than shallow pages. The reality is that Google can do that only when there is a communication mechanism between readers and Google servers. What Google does was they selected sites which they considered as content farms like ezines, hubpages etc and they devalued the entire sites.

    If you look closely there are lot of blogspot sites which has got positive impact on Google Panda updates. I believe Google Panda is a mere implementation from Google to monetise more using various adsense and adwords channels at the same time they created a camouflage among Google customers that they are caring customers more which obviously not.

    Great article.

    As a novice just starting out in the world of SEO it’s interesting to hear about this update by Google and the direction it’s heading in. It would be interesting to know what Google defines as ‘Low Quality Sites’ and like Gices said, punishing for ‘thin content’ seems wrong.

    The example used with the tech blog – When purchasing a new product the first thing I do is check multiple websites now with this update will I be pushed towards only seeing one website and the others with similar material have been pushed down the SERPs

  7. Gemma says:

    Excellent article, perhaps one of the best articles on Panda. Interestingly, a few minutes ago I came across the following post on Twitter.

    Basically, Google has just released some guidances/tips on dealing with Panda if your website has been hit. I really like the last point Amit Singhal has made in that article.

  8. Mark Cadwaladr says:

    Brilliant article!! Wow, did I just get enthused about search algorithms? Blimey.

    Yep, as a client I’ve heard enough in press about Panda but… zzzzzzz… what was I saying? Oh yes, booooring! I’ll let others worry about it and drop ‘Oooh, that bloody Panda’ into conversations like I know what I’m on about.

    I digress.

    Well, that article made sense to a human, kept my attention and left me with actionable insight.

    Cheers Briony!

    I had thought about playing more on the Panda puns with a Teddy Bear Picnic rehash, something along the lines of:

    “If you go down to the SERPs today, you in for a big surprise…
    If you go down to the SERPs today, you’d better go in disguise.
    For every poor content site that ever there was, they’d better run and hide because;
    Today’s the day the Panda Update PWND your website.”

    I thought I should probably leave it at “Bamboo-zled” and save the nursery rhymes for the next algorithm update (oh, please let it be called Ring-A-Ring-A-Roses)

    Thanks for that link, Gemma. And the point of the “latest advice from Google suggests that there are has been more than a dozen changes since Panda was rolled out” emphasises Google’s battle against SEOs producing content for algorithms first and users second.
    And Singhal’s comment in that article will make anyone want to run and cannibalise any thin content pages to appease the Panda. Coherent structure, quality content, enabled social sharing… the usual whitehat, evangelical spiel!

    Good post, I would add that article sites are major losers too, ezine articles, articlebase and the like have had their traffic slain by the panda. I still today however see scraper sites nicking my content and ranking well for it, still work to be done and has made me and others reassess our content.

  11. Great article.

    I was really happy, both as a search engine user and someone involved in SEO, to see the effects of Panda.

    Users want great content, relevant to their search. It’s Google’s job to deliver it, which means it’s an SEO’s job to make sure their clients’ sites ARE it.

  12. Nice article!

    We’ve all known for a long time just what we have to do in order to help our clients to rank highly on the SERPS.

    ‘Content is King’ and always has been. So when business owners wake up one morning and find their rankings have been shot to pieces they must question the quality of their Seo agency.

    Oh by the way, I love the cheeky Panda image above. Panda Power!

    It’s time to move on and let the others fall behind.
