Can you believe it has been four years since the Google officially released their Panda algorithm update? Before that, Google was getting a tremendous amount of flack over the quality of their search results and then Panda touched down.
Panda 1.0 was released on February 24, 2011 - four years ago today and it may have been the most significant quality algorithm Google has released to date, even more so than Penguin.
Since then, we've covered the Panda update hundreds of times. We tracked over 20 confirmed updates and likely 50+ unconfirmed updates to the algorithm.
One thing is for sure, Panda is part of the SEO handbook. It fundamentally changed how many SEOs worked on sites. It fundamentally changed which type of web sites ranked well in Google. It fundamentally changed hundreds, if not thousands, of businesses and how they operate online. It changed the search landscape tremendously.
To see all our coverage on Panda, go here.
I know Penguin was substantial for many SEOs because of the link aspect, but Panda did impact more sites overall. It also tremendously cleaned up Google's quality perspective almost overnight.
