SERPs with Featured Snippets dropped 40% day over day, according to MozCast, to their lowest point since 2015. On closer inspection, these were disproportionately targeted at YMYL queries and heavily focused on short queries (especially 1-word queries) (health and finance).

With widespread reports of massive impact, Google confirmed a “broad core algorithm update.” It went live over the course of about a week, peaking on August 1-2. Although there was a large-scale impact in all verticals, this update seemed to disproportionately affect sites in the health and wellness vertical.

The reversal of all previous Penguin penalties was the second phase of Penguin 4.0. This appeared to happen after the new code was implemented, and it could have taken up to two weeks. On October 6th (116°), post-Penguin activity peaked once more, but it’s unclear whether this was due to Penguin or a new update. After October 6th, algorithm temperatures began to drop.

The first phase of Penguin 4.0 was the rollout of the new, “gentler” Penguin algorithm, which devalues bad links rather than penalizing sites, which happened around September 22-23. Although the exact timeline is unknown, we believe this update took at least a few days to complete and may have coincided with an algorithm temperature spike (113°) on September 27th.

Google released another Penguin update after a four-and-a-half-month hiatus. Given the 2.1 designation, this was most likely a data update rather than a major Penguin algorithm change. Although some webmasters reported being hard hit, the overall impact appeared to be moderate.

Google announced the “Hummingbird” update on September 26th, but it appears to have been released a month earlier. Our best guess is that it’s linked to a MozCast spike on August 20th, as well as numerous reports of flux between August 20 and 22. Hummingbird has been compared to Caffeine, and it appears to be a core algorithm update that will continue to power changes to semantic search and the Knowledge Graph for months.

A Panda update was confirmed by Google, but it was unclear whether it was one of the 10-day rolling updates or something new. The implication was that this was algorithmic, and that it may have “softened” some of the Panda penalties previously imposed.

Matt Cutts of Google responded on Twitter, predicting a “multi-week” algorithm update between June 12th and “the week after July 4th.” The nature of the update was unknown, but there was a lot of volatility in the rankings during that time, peaking on June 27th (according to MozCast data). Google appears to have been experimenting with some changes that were later reversed.
