According to Google, the spam update in August 2025 is already implemented all over the globe.
According to the status page, the update began on August 26 and has been completed on September 22.
What This Update Targets
Google categorizes such spam updates as significant developments to its automated spam-prevention systems, such as spambrain.
These releases are meant to have a more effective detection and reduction of spam in search results as opposed to re-ranking the entire index.

Early Observations
The analysis of independent visibility of SISTRIX defines August update as penalty-only.
They write that the examples of spammy domains going down in visibility can be observed, but the impact of the spam update does not seem to bring significant changes to the SERPs yet.
That is, there will not be straightforward winners, but only removals or demotions in the case of spam.
What To Do Next
When you find that your website is performing poorly in the rollout period, then begin by ensuring that your policies are at pace with each other instead of seeking solutions in the short term.
According to Google, such sites which have been spammed will fail to rank high or even fail to show up in the search results. Improvement can contribute to a better performance of your site when automated systems are sure that your site is compliant once again.
Only few positive outcomes are to be expected. Given that this update relates more to enforcement than a general increase in rankings, you might notice fewer non-compliant pages removed and fewer more pages being ranked higher.
Looking Ahead
The spam updating is also a continuous process and Google continuously updates its systems as well to keep pace with developments in tactics. And when repairing problems, allow Google systems to re-consider the pages in question.
