01
September 2026 spam update complete (~13d 16h)
Official
What happened
Status Dashboard: rollout complete as of October 8, 2026 (incident end ~01:00 US/Pacific). Duration ~13 days, 16 hours from Sep 24 09:15 PT—near Google’s “up to two weeks,” longer than Mar/Jun/Aug 2026 spam updates (<~3 days). Global, all languages; no named tactic.
Why it matters
Lock the analysis window Sep 24–Oct 8 in GSC. Prefer sustained impression/click shifts over rank-tracker blips. Recovery can take months of compliance learning.
