Glenn Gabe from G-Squared Interactive put together and amazing article explaining the details behind the recent updates to Googles Panda and Penguin updates. I am pulling this article directly from Search Engine Journal as it needs no rewrite or explanations.
Penguin or Panda? How To Determine Which Google Algorithm Update Impacted Your Website
Ever since Google rolled out Penguin 1.0 on April 24th, I’ve been heavily analyzing websites that were hit by the update (I’ve now analyzed close to 75 websites hit by Penguin). Based on my analysis, I have written several posts covering my findings. In my latest post, An Update from the Over Optimization Front Lines, I explained how important it is for webmasters to know exactly what hit them before taking action. I know that sounds simple, but I’ve had several companies contact me believing they were hit by Penguin, when in fact, they were hit by Panda.
Panda, Penguin, and The Algorithm Sandwich
After Penguin 1.0 was released, Google also explained that a Panda update was rolled out a few days before Penguin (on 4/19). Then, to make matters even more confusing, Google rolled out a Panda refresh on 4/27. To quickly recap, Panda rolled out on 4/19, then Penguin on 4/24, and then a Panda refresh on 4/27. Yes, that’s essentially an algo sandwich special, with a side of insanity. As you can imagine, webmasters that aren’t extremely familiar with SEO could very easily think they were hit by Penguin (since that was the primary topic during the time period).
