 |

We’ve all noticed the Panda 2.2 update from Google. And a lot of us have experienced some nasty drops in SERPs. Possibly you have experienced it from Panda 1.0 and still haven’t come back.
If you are going to be able to work in the post-Panda environment, its going to help you to understand how Panda works, and why some sites get hit.

Google’s Algorithm 101
So as any experienced marketers know, the Google algorithm is really a mathematical calculation that takes into account dozens, if not hundreds of factors from every site. Things like domain name, domain age, keyword density, link structure all have their respective effects on where Google places a site on its rankings.
We also know that Google is constantly changing this algorithm, mostly in minor, unnoticeable ways. The equivalent of adding “a pinch of salt” to a pot roast.
When Google makes major changes, we call them “updates”. Be they the Panda, Mayday, or Florida update.
Different Types of Updates
Not all updates are algorithmic. For example, years ago Google used to do an “index update” every month or so, when it would suddenly dump millions of new pages it had found into its existing collection.
This influx of new content caused ranking changes that could take days to settle down, hence the nickname of the “Google Dance.” But the changes were caused by the algorithm sorting through all the new content, not because the algorithm itself had changed.
Algorithm updates definitely have the power to totally alter rankings, and have done so in the past. But despite popular opinion, Panda is not an algorithm update! Instead, Panda is more like a new level of data feeding into the existing algorithm that evaluates “thin content”. This is why we are repeatedly seeing new people getting nailed…
So What Happened?
Essentially Panda works a lot like PageRank in its early days. For those of you who aren’t familiar, PageRank is one factor that Google uses to measure your site. Based on backlink analysis, the PageRank system will assign your site an “authority score”. Because the analysis of backlink authority was so labor intensive, and since backlink structures don’t change so often, the PageRank updates only would happen every few weeks or so. (Although I believe that now they are almost constant but just the reporting is delayed).
When Google adds a new level to it’s algorithm, the changes may happen immediately if Google already has the necessary data in its index to make the changes. If not, you may notice rankings changes weeks or even months after Google collects the new data in its index.

Panda is just that. Google uses Panda the same way it used to fix “Google Bombs”. Every few weeks, Google will “flip the switch”, run the analysis software, and suddenly alter the rankings. This is why we’re seeing what seems to be new versions of Panda that is attacking more and more people.
The Panda filter isn’t running all the time. Right now, it’s too much computing power to be running this particular analysis of pages.
* Panda Update 1.0: Feb. 24, 2011
* Panda Update 2.0: April 11, 2011 (about 7 weeks later)
* Panda Update 2.1: May 10, 2011 (about 4 weeks later)
* Panda Update 2.2: June 16, 2011 (about 5 weeks later)
So what does this mean?
Basically this means that if you were not hit previously, you might be hit now. It also means that if you make appropriate content changes, you may not see improvements for 4-6 weeks when Google runs the Panda application again.
Over time (like PageRank) Google will develop the ability to constantly monitor content quality.
For now, make sure you post as high quality content as possible. Avoid keyword stuffing, cloaking, hidden links, trashy spun content, etc.
If you’ve been hit, be patient. Make the necessary changes and find other methods of traffic in the meantime.
