Google has confirmed that a bug with the Google October 2023 core update caused an issue with Google Discover traffic. The bug was identified on October 5, 2023, and was fixed on October 31, 2023. Google stated that some websites may see an increase in Discover-related traffic as a result of fixing the bug. If websites have experienced unusually low Google Discover traffic since October 5th, it may be related to the bug. However, Google Discover traffic is not something that can be consistently relied upon.
