Google’s September 2026 spam update began Sept. 24. Unlike typical two-day spam rollouts, Google said this one would take about two weeks, and Search Engine Roundtable has tracked several waves: Sept. 25–27, Sept. 30, and again Oct. 4–6.
If a client’s traffic moved after Sept. 24, check it against those dates before changing anything.
