Spanning Beyond Core Changes



Alongside these major updates, 2023 witnessed developments in various aspects of Google’s algorithm to identify poor-quality AI-spun content and link spam. These included the introduction of a ranking improvement aimed at surfacing 'hidden gems' from social media and blogs, the launch of a more tailored search experience, and the testing of 'Notes' on search results as a Labs experiment.

There are also a series of unconfirmed algorithm updates throughout 2023 that saw large spikes and flux in the Google rankings for many sites, that brings the potential total number of major updates to 12 for 2023. These fluctuations in ranking results were observed on February 15, July 17, and August 18. Google did not provide any details on these alleged algorithm update rollouts, and at this time, they remain unconfirmed.

Google has said it rolls out many minor algorithm updates on a frequent basis, but it does not provide any information on these smaller changes to its search ranking algorithm, which suggests that despite these updates having a significant impact, Google viewed them as minor updates to its core algorithm.
