2003 February Search algorithm update Google announces the Boston update at SES Boston.[7]
2003 April Search algorithm update Google announces the Cassandra update. The update claims to crack down on link spam, including mutual links between co-owned websites, as well as hidden text and hidden links.[7][11]

2007 June Search algorithm update The Buffy update happens. It is not considered a deliberate update, but rather an accumulation of many smaller changes.[7][40][41]
2008 March/April Search algorithm update The Dewey update seems to lead to a large-scale shuffling of results. Some observers believe that Google is pushing its own properties, such as Google Books, but evidence of this is limited.[7][42]

2010 September 8 User experience Google launches Google Instant, described as a search-before-you-type feature: as users are typing, Google predicts the user's whole search query (using the same technology as in Google Suggest, later called the autocomplete feature) and instantaneously shows results for the top prediction.[59][60][61] Google claims that this is estimated to save 2–5 seconds per search query.[62] SEO commentators initially believe that this will have a major effect on search engine optimization, but soon revise downward their estimate of the impact.[7][63]
2010 November 9 User experience Google launches Instant Previews, a feature where users can view previews of the ranked pages by hovering over the links in the search engine results page.[7][64][65][66]
2010 December 1 Search algorithm update Google updated its algorithm to penalize websites that provided a bad experience to users. The update was motivated by a November 26 New York Times story about a fraudulent company called DecorMyEyes that used the publicity generated by negative customer reviews to rise in the search engine rankings.[7][67][68]
2010 December Search algorithm update (announcement/confirmation) Both Google and Bing (Microsoft's search engine) indicate that they use social signals, including signals from Twitter and Facebook, to rank search results.[7][69][70]

2011 January 28 Search algorithm update Google launches its Attribution algorithm change to better sieve out websites that scrape content. Matt Cutts claims that slightly over 2% of search queries are affected, but less than 0.5% of results change noticeably.[7][73][74]
2011 February 23–24 Search algorithm update Google launches Google Panda, a major update affecting 12% of search queries. The update continues with the earlier work of cracking down on spam, content farms, scrapers, and websites with a high ad-to-content ratio.[7][75][76][77] The rollout is gradual over several months, and Panda will see many further updates.
2011 March 30 User experience, incorporation of user feedback Google launches the +1 button so that users can offer feedback on search results.[78] Commentators liken this to the like button seen on Facebook.[79][80]

2011 September 30 Search algorithm update Google rolls out Panda 2.5.[7][98] Although the specifics of the update are unclear, a few sites gain significantly and a few others lose significantly.[99] Other minor flux updates occur on October 3, October 5 and October 13, and some commentators call these Panda 3.0 and 3.1.[7][100]
2011 October 18 User experience, SEO data Google announces that they will start encrypting all search queries for security purposes.[101] This disrupts organic keyword referral data for many websites, making search engine optimization harder.[102]
2011 November 3 Search algorithm update Google announces a Freshness update that would give priority to fresher, more recent search results, and claims this could affect 35% of search queries.[103][104][105] The algorithm largely affects time-sensitive queries. A number of sites gain and many others lose as a result of the update.[106]

2012 January 10 Search algorithm update, user experience Google launches Search Plus Your World, a deep integration of one's social data into search.[111][112] SEO commentators are critical of how the search results favor Google+ and push it to users, compared to more widely used social networks such as Facebook and Twitter.[113][114][115][116]
2012 January 19 Search algorithm update Google updates its algorithm to introduce a penalty for websites with too many ads "above the fold". The update has no name, but some SEOs use "Top Heavy" to describe the update.[7][117]
2012 February 27 Search algorithm update The update, codenamed Venice, was announced as part of Google's end-of-February 40-pack update. Venice seemed to give substantially increased weightage to local results (location inferred from the user's IP and other signals) for many search queries, such as those looking for businesses of various types in the vicinity.[7][118][119] On the same date, Google rolls out Panda 3.3, which it bills as a data refresh rather than an algorithm change.[120]
2012 March 23, April 19, April 27 Search algorithm update March 23: Google rolls out Panda 3.4, which is claimed to affect 1.6% of search queries.[121]

2012 August 10 Search algorithm update Google announces that it will start penalizing websites with repeat copyright infringements, possibly as measured by DMCA takedown requests.[137] Some SEO commentators call this the Pirate update.[138]
2012 September 27 Search algorithm update Google rolls out a major update to Google Panda (the update is to the underlying algorithm, rather than merely being a data refresh), that would be dubbed Panda 4.0, but SEO commentators decide to simply call it Panda #20. The change is estimated to have affected 2.4% of search queries.[7][139]
2012 September 27 Search algorithm update Google announces changes in the way it handles Exact-Match Domains. The change is estimated to have affected 0.6% of search queries.[140][141]
2012 October 5 Search algorithm update Google releases minor tweaks to Penguin, affecting about 0.3% of search queries. SEO commentators call it Penguin #3, following the lead of Panda in ditching the use of 1.x notation in favor of labeling updates by number.[7][142][143]

2012 December 4 Search algorithm update Google adds Knowledge Graph to non-English queries, and says that the change goes beyond translation and also adds enhanced Knowledge Graph capabilities.[7][144][145]
2013 March 13–14 Search algorithm update Google rolls out Panda #25. Remarks by Matt Cutts at SMX West give people the impression that this is the last update to Panda as a distinct entity and it will thereafter be integrated into the core algorithm.[7][146][147] On June 11, 2013, Cutts clarifies that Panda updates roll out over 10-day periods every month and are not continuous.[148]
2013 May 22 Search algorithm update Google rolls out a new version of Google Penguin that it calls Penguin 2.0, which SEO commentators call Penguin #4.[149][150]

2013 August 21–22 (approximate date for rollout), September 26 (announcement) Search algorithm update Google releases Google Hummingbird, a core algorithm update that may enable more semantic search and more effective use of the Knowledge Graph in the future.[7][153][154]
2013 October 4 Search algorithm update Google announces what it calls Penguin 2.1, its fifth version of Penguin, claiming to affect 1% of searches. The effect seems minor.[7][155][156]
2014 May 16 Search algorithm update Payday Loans 2.0 algorithm change is purely low quality external link related and over-optimization. This specifically goes after high search, spammy queries such as “Payday Loans”. Google is trying to devalue sites that perform in link buying and other black hat methods to game the algorithm.

[157]

2014 May 20 Search algorithm update Panda 4.0 was implemented to devalue sites that contained poor / low quality content. This has been an ongoing battle that Google has been chipping away at for years. Google has claimed that the algorithm change has impacted roughly 7.5% of all search queries. [158]
