Google Hits eBay With Manual Penalty In Search Results

What really happened to eBay dropping in Google’s search results this week? A source familiar with the situation tells Search Engine Land that Google hit eBay with a manual penalty this week.
A manual penalty is when a human being at Google reviews a site and decides that it deserves some type of slap. Previously, it was assumed eBay was hit by the Panda 4.0 Update that rolled out this week, where a wide-range of sites were with with automatic penalties.
That might also be the case — eBay might have been hit by Panda in addition to a manual penalty, which was reported earlier by Re/Code.

Google Begins Rolling Out Panda 4.0 Now

Google’s Matt Cutts announced on Twitter that they have released version 4.0 of the Google Panda algorithm.
Google’s Panda algorithm is designed to prevent sites with poor quality content from working their way into Google’s top search results.
But didn’t Google stop updating us on Panda refreshes and updates since they are monthly rolling updates? Yes, but this is a bigger update.
Panda 4.0 must be a major update to the actual algorithm versus just a data refresh. Meaning, Google has made changes to how Panda identifies sites and has released a new version of the algorithm today.
