Penguin #3 — October 5, 2012
A very minor and almost insignificant Penguin update by Google.
 “Phantom” — May 9, 2013
Named phantom because it was never announced by Google, nor by anyone affiliated with Google. By SEO’s around the world agree that there was some update activity around this period which caused traffic drops in some sites and traffic increase in others.
Domain Crowding — May 21, 2013
Google believes that Domain Crowding is a form of spamming and hence wanted to address it quickly.
For this the algo experts at Google came up with the idea of curbing domain crowding with the help of an update to the Google search algorithm. This is what resulted from that.
Penguin 2.0 (#4) — May 22, 2013
An Official Penguin Update as stated by Google was released and it affected about 2% of all the English search results.This is something that we bloggers and webmasters would like to call - A big update.
Many sites saw huge drops in traffic around this period.
“Payday Loan” Update — June 11, 2013
Google created the PayDay Loan update to remove spammy sites from the most spammy niches such as Payday Loans, Education sites, Coupon sites etc.
Panda Dance — June 11, 2013
While not an actual Panda update, Matt Cutts made an important clarification at SMX Advanced, suggesting that Panda was still updating monthly, but each update rolled out over about 10 days. This was not the "everflux" many people had expected after Panda #25.
