Penguin Data Update Yesterday

There appears to have been a Penguin data update either yesterday or early today.

What makes me so sure?

Well, I set up a little Penguin trap. I built a one-page site, tuned for a nonsense term, and built about a dozen links to that page with the nonsense term as anchor text.

Then, I waited until it ranked #1 for that term…that took just a couple of days. The pages that linked TO that page all rank for that term, as well.

So, once my nonsense site ranked #1 for that term, I disavowed all links.

And waited. Till today.

BOOM. After not moving a single spot for the past month, it suddenly dropped 9 places.

  1. Genius. Of course, this could mean something other than Penguin…

    1. Maybe Google has changed how and when they choose to apply disavows

    2. Maybe they run the disavow a few days before a penguin update

    3. Maybe a different link based algo update will roll out.

    Nevertheless, this is a fascinating technique which should be done continuously to monitor disavow processing by Google.

  2. This sounds like evidence of a re-crawl, as a result of which the information in the disavow files gets applied. Presumably the purpose of the re-crawl is so that they can then roll out Penguin (or something) with fresh data. This doesn’t sound like Penguin itself.
