Google has been granted a US patent by the US Patent and Trademark Office for its Panda algorithm - three years after it initially rolled out.
Interestingly Navneet Panda and Vladimir Ofitserov are listed as the inventors of the algorithm, a nod in the direction of where it got its official name. The patent was actually filed for back in 2012, a while after Panda had started to work targeting unethical SEO methods.
Putting the cat firmly amongst the pigeons, Panda was unleashed by Google back in February 2011 to tackle spammy websites, although up until its name was given as Panda by Google's Amit Singhal in a Wired interview, its rumoured working title had been 'Farmer'.
This was picked as the change was designed to target people scrapping content and using it on their own site - in essence, creating a content farm.
The patent goes into great depth in detailing how exactly Google ranks pages based upon the links pointing to them. It talks about how the system can "determine whether a query is navigational to a resource by accessing data that identifies queries that are classified as navigational to each of a number of resources."
It also goes into detail on how the algorithm can also understand acronyms and has the ability to rank certain pages with such a result.
