June 2021 spam updates
Two rapid spam updates released within a week, overlapping with the June 2021 core update.
What changed
Google announced a spam update on 23 June 2021 followed by a second part on 28 June, both completing within a day of release. They targeted web spam broadly rather than a named tactic, and Google pointed publishers at its webmaster guidelines rather than issuing new advice. Their overlap with the June core update made attribution of ranking changes difficult during that period.
Timing
Rollout began 23 June 2021. Google declared it complete on 28 June 2021, 5 days later. Rankings typically remain unstable for the whole rollout window, so measurements taken inside it are not a reliable read on the outcome.
