Google's "Phantom update" refers to a series of largely unverified updates by Google, which began to roll out in mid-May 2015. These algorithm tweaks have caused significant fluctuations in search rankings globally, but unlike the Penguin update or the Panda update, no consistent pattern has been observed.
In May 2015, numerous SEO experts globally noted dramatic shifts in search results. Several websites experienced a significant drop in visibility, affecting various types of websites, from advisory platforms to e-commerce and news sites. There was speculation about a new iteration of the Panda or Penguin algorithms. In June 2015, Google confirmed updates related to website quality assessment; both Gary Illyes and John Müller commented on these changes. The SEO community dubbed it the "Phantom" update, or simply a "quality update," due to Google's silence on the specific website areas impacted.
Since May 2013, there have been five Phantom updates:
The "Phantom" updates did not target a specific group of websites, but they did lead to a rapid decline in rankings for many. The primary goal of these updates was to enhance website quality and, consequently, improve search result quality. Google continually adjusts its core algorithm to achieve this, though it doesn't specify which website elements are impacted.
When focusing on website quality, various optimization aspects can be relevant to the Phantom update.
Despite the elusive nature of Phantom updates, the solution for webmasters is straightforward: enhance website quality. Key areas include:
Additional quality factors, such as internal linking, meta information usage, and incoming/outgoing links, can also influence the Phantom algorithm.
The timing of Google's next core algorithm update remains uncertain. However, the focus on "website quality" persists. Due to limited update details, webmasters must prioritize optimal quality across all website aspects. Google's mobile update demonstrated its ability to announce changes clearly, prompting global webmaster compliance. With Phantom updates, Google's strategy of minimal detail disclosure appears to encourage rigorous website optimization. Google's interest in high-quality websites is strategic, as superior search results enhance its reputation, ultimately boosting advertising placements and clicks.
It is likely that Phantom updates will eventually become continuous like Penguin and Panda, reducing the stark impact observed in previous updates.
