Core Update, Reviews Update November 2023 -Status, Examples and Data

Quickly following the previous two updates in October 2023, the Core update and Reviews update have overlapping dates which makes it more difficult for SEOs to analyse the separate impacts of the two core changes. This post shows data and examples that will help you identify the effects of the two core updates.

The November 2023 Core update was announced on the 2nd November. Our data shows that the SERP movements started on the 2nd November.

The November Reviews update was announced on the 8th November and some domains appear to have reacted directly after the 8th. Google stated that this would be the last time that the update would be announced as it is “being improved at a regular and ongoing pace.”

Info-pins in SISTRIX Visibility Index Graphics have been set accordingly.

Details of all previous Google updates are available in the complete list of Google updates.

How to check the impact of Google updates

The Visibility Index is a live indicator of organic search visibility. Use the latest data to monitor and analyse, down to URL level, the latest changes for your domains and those of your competitors.

Some candidates have been seen outside these dates but they may be changing due to other effects. One example is, the British Library, whose very large presence was negatively affected by a cyber attack at the tail end of October and into November.
