The SEO community has been noticing sharp changes in the search result in Google since May 1st 2015. The whole community was anxious to know about the update going on for so long in the Google search engine. Some of the community members thought it is the much-awaited Panda algorithm update or maybe Penguin update that may be underway. But, Google has confirmed that it is neither Panda nor Penguin but it is a core search algorithm update. It has also informed that they will continue to bring more core search algorithm updates in the future as well to provide a better quality search result to users.
The official statement from Google says:
This is not a Panda update. As you know, we’re always making improvements to our search algorithms and the web is constantly evolving. We’re going to continue to work on improvements across the board.
This update can be compared to the Google quality update affecting the search result all across the web. This is the sole reason that SEO community noticed changes in ranking since May 1st since the beginning of this update.
Interestingly, most of the automated tracking tools like Mozcast showed huge spikes in term of changes happening in Google search results. Most of the engineers or SEO search scientists thought it may be HTTPS algorithm being updated and given more weight. But, Gary Illyes from the Google team said on Twitter it is the not the case. Another reason for showing spikes by the tools in the Google search result is due to Wikipedia changing of all its URLs to HTTPS. This might have changed the 1-5 Google search results causing the automated tools to spikes abruptly.
From this statement, we know that it is not Panda, Penguin or HTTPS update but simply a normal Google core search update. In core search algorithm updates, Google team don’t share any detail with the search community.
