Characteristics of Google October 2023 Core Update

On October 5, 2023, Google rolled out a core algorithm update. Although Google published limited information on it we can characterize our research.

  1. This is a core algorithm update.
  2. It will influence ranking factors.
  3. It will take two weeks to complete.

The Google October 2023 Core Update is currently underway, running in tandem with the October 2023 Spam Update, which was officially introduced on October 4, 2023, as detailed in this report: “Google Releases October 2023 Spam Update.” While the Spam Update enhances the spam detection system’s scope across numerous languages and spam categories, the Core Update is dedicated to refining Google’s algorithms and systems in their evaluation of content on a broader scale.

Regarding the simultaneous release of Google algorithm updates, Google Search Liaison provided insights on the matter during a comment made on X.

“Normally, we do try to keep updates like these apart, but it’s not always possible. But for anyone trying to understand changes, it’s pretty straight-forward. If you don’t spam, and see changes, then it might be the core update. If you do spam and see changes, it’s probably the spam update. In particular: We released a spam update yesterday. Sites that don’t spam shouldn’t see changes because of this. Learn more about spam updates here.

“Today we released a core update. That’s different from a spam update. It’s a general improvement in how we rank. Many sites will see no changes because of this, and it has nothing to do with spam. This explains more about core updates.”

As Google states in its Search Central documentation on Core Updates: “There’s nothing wrong with pages that may not be performing as well as they were before a core update. They haven’t violated our spam policies, nor been subjected to a manual or algorithmic action, as can happen to pages that do violate those policies. In fact, there’s nothing in a core update that targets specific pages or sites. Instead, the changes are about improving how our systems assess content overall. These changes may cause some pages that were previously under-rewarded to do better in search results.”
Should the October 2023 Core Update have an adverse effect on your website, Google provides a set of inquiries to assist in self-assessing your content during a site audit. Measuring your content against these questions can aid in determining its utility and reliability for search queries, its ability to deliver an exceptional user experience, and its capacity to exhibit expertise, authority, and trustworthiness (E-A-T) – all pivotal factors considered by Google’s search algorithms and ranking systems when ranking search results.
