Saying that it could take months to fully roll out, Google announced what was most likely a Panda data refresh. The effects were unclear what with no clear signs of a major algorithm update.
Following many reports of large-scale ranking changes, Google acknowledged a core algorithm change impacting “quality signals”. This update seems to have had a broad impact, however, Google didn’t reveal any specifics about the sort of metrics used or ‘signals’ being targeted.
Google announced this particular algorithm update pre-launch, stating they would be starting to roll out the update globally from the 21st April. Effecting only mobile search and individual page, the update introduces mobile-friendliness as a ranking factor. Studies have shown this is now making a big impact on Desktop searches which Google originally said wouldn’t happen.
Multiple SERP trackers and webmasters reported major variations in Google SERPs. Speculation on the update ranged from it being an e-commerce update to a mobile usability update. Officially Google did not confirm an update.

Google’s major local algorithm update, dubbed “Pigeon”, expanded to the United Kingdom, Canada, and Australia. The original update back in July 2014 hit the United States. Even though the update was confirmed on the 22nd it believed that it may have rolled out as early as the 19th.
A representative from Google said that Penguin had shifted to continuous updates, moving away from infrequent, major updates. This claim seemed to fit the ongoing fluctuations after Penguin 3.0 (including unconfirmed claims of a Penguin 3.1).
More than two years after the original DMCA/”Pirate” update, Google launched another update to combat software and digital media piracy. After many criticisms that Google is not doing enough against Piracy it updated its filter to help stem piracy. It works similar like Panda or Penguin. This update was highly targeted, causing dramatic drops in ranking to a relatively small group of sites.
A year after the previous Penguin 2.1 update, Google launched a Penguin refresh. This update appeared to be smaller than expected (<1% of US/English queries affected) and was probably data-only and not a new Penguin algorithm. The timing of the update was unclear and Google claimed it was spread out over “weeks”.

Google shook the local results with an update that dramatically altered some local SEO results and modified how they handle and interpret location cues. Google claimed that Pigeon created closer ties between the local algorithm and core algorithm(s).
John Mueller made a surprise announcement (on June 25th) that Google would be dropping all authorship photos from SERPs (after heavily promoting authorship as a connection to Google+). The drop was complete around June 28th.
Multiple SERP-trackers and many webmasters reported major flux in Google SERPs. Speculation ranged from an e-commerce focused update to a mobile usability update. Google did not officially confirm an update. Many in the SEO community hinted on SEO is dead well back linking.
Google confirmed a major Panda update that likely included both an algorithm update and a data refresh. Officially, about 7.5% of English-language queries were affected. While Matt Cutts said it began rolling out on 5/20, our data strongly suggests it started earlier.
Prior to Panda 4.0, Google updated it’s “payday loan” algorithm, which targets especially spammy queries. The exact date of the roll-out was unclear (Google said “this past weekend” on 5/20), and the back-to-back updates made the details difficult to sort out.
Major algorithm flux trackers and webmaster chatter spiked around 3/24-3/25, and some speculated that the new, “softer” Panda update had arrived. Many sites reported ranking changes, but this update was never confirmed by Google.
Google “refreshed” their page layout algorithm, also known as “top heavy”. Originally launched in January 2012, the page layout algorithm penalizes sites with too many ads above the fold.
