Google consistently evaluates and updates its algorithms. There may be a whole bunch and even hundreds of particular person adjustments per yr.
Google does verify among the main updates, resembling web site repute abuse, the March 2024 core replace, and the November 2023 critiques replace.
However, typically, Google is not going to officially confirm an replace, and these are solely picked up by excessive volatility within the SERPs.

The volatility talked about within the tweet was noticed round Could 7, a day after Google introduced that it rolled out a reputation abuse update with handbook actions, with the algorithmic half following later.
