Biggest Losers in Google’s Algorithm Update

We usually don’t post anything on SEOmistry on the weekends as we let our readers take a bit of a break to soak in all the info that has been thrown at them over the past week however today I really wanted to share this with you all in light of the new Google update.

On 24/02/2011 Google announced a change in their algorithm targeting low quality sites (via Google blog). It has been reported that this algorithm change has impacted almost 12% (11.8%) of queries but who really has been affected by this major change by Google. I have compiled a list of the biggest losers in terms of rankings from a variety of different sources. This gives us a good idea of what not to do and what the new algorithm change actually targets.

According to Sistrix they managed to figure out the biggest losers of the algorithm change by analysing a data set of over 1 million keywords which they studied the day before and day after the major change. They studied the change in rankings between the two days and created the table below.

This table from Sixtrix shows us the URL, percentage SISTRIX loss, SISTRIX before Google update, SISTRIX after Google laptop and the number of keywords that the respective site rank for within the Sistrix 1 million dataset both before and after the change. The table is sorted from largest absolute SISTRIX loss to least and by judging by the sites within this Sistrex top 25 biggest loser list it seems as though Google has done a great job with penalising low quality content farms.

According to SEOClarity who have analysed a data set of 60,000 keywords looking at before and after rankings to come up with their biggest losers and winners.  From this data they have come up with the top 10 losers in terms of overall rankings. Here are their top 10:

  1. TheFind.com
  2. BizRate.com
  3. ShopWiki.com
  4. EzineArticles.com
  5. HubPages.com
  6. Buzzillions.com
  7. Shopping.com
  8. Suite101.com
  9. Kaboodle.com
  10. AssociatedContent.com

In addition to the biggest losers SEOclarity also looked at the sites tat received the biggest gains. Here are the top 10 in terms of gains.

  1. Amazon.com
  2. eHow.com
  3. NexTag.com
  4. Wikipedia.com
  5. Walmart.com
  6. Target.com
  7. Etsy.com
  8. Answers.Yahoo.com
  9. Sears.com
  10. bestonlinecoupons.com

It seems as though brands have benefited greatly from the recent change. Surprisingly eHow.com and anwers.yahoo.com experienced significant gains too. According to the data eHow.com experienced the 2nd highest gain behind Amazon.com.

Despite Google not admitting that they are targeting content farms with their new update the stats show otherwise with nearly all the biggest losers being huge content farms. There are some exceptios however such as Demand Media’s eHow.com which very surprisingly received a gain in rankings. Here s Demand Media’s statement in regards to the Google Algorithm update:

As Google continues this fight against low quality “content farms” it is becoming increasingly important to ensure you pump out high quality unique content. It is always good to remember when doing SEO work to try to “work with” the search engines rather than trying to “game” or trick them.

Would love to hear what you guys think about the recent algorithm change and the biggest losers/winner above…
