What Spam Updates Target
Spam updates improve Google's automated systems, including SpamBrain, that detect content violating its spam policies. Typical targets include:
- Scaled content abuse (mass-produced pages with little value, whether written by people or AI)
- Site reputation abuse (third-party content published on a host site to exploit its ranking signals)
- Expired domain abuse
- Link spam, cloaking, doorway pages and hacked content
Spam updates differ from core updates, which broadly reassess content quality and relevance. Google's last broad core update was in May 2026.
What to Do If Your Traffic Changed
- Confirm timing. Compare Search Console data before September 24 and after the rollout finishes.
- Check for manual actions in Search Console, which are separate from algorithmic updates.
- Review spam policies honestly against your site, especially large batches of thin pages or hosted third-party content.
- Improve rather than hide. Removing or substantially improving violating content is the path to recovery; recovery can take months as systems re-evaluate.
Why It Matters
With AI tools making mass content generation cheap, Google has repeatedly signalled that scale alone is not a strategy. Sites that publish original, well-sourced and genuinely useful material are least exposed to spam updates.
What Happens Next
Google posts completion notices on the dashboard. Many SEO analysts expected a broad core update in the second half of 2026, but none had been announced as of October 1.
FAQ
Is a spam update the same as a penalty?
No. A spam update is an algorithmic change. Manual actions are separate and are reported in Search Console.
Does using AI content trigger spam updates?
Not by itself. Google's policies target low-value content produced at scale to manipulate rankings, regardless of how it was made.
