Early Industry Observations
Some SEO professionals have reported declines among websites using highly templated, programmatic, or repetitive pages. However, these are early observations—not confirmed targets of the September spam update.
Site owners should avoid concluding that AI-assisted content, programmatic SEO, affiliate pages, or any other single format has been universally targeted. Google’s spam policies focus on whether pages are created primarily to manipulate search rankings rather than genuinely help users. Google’s spam policies
What Website Owners Should Do?
Websites that notice unusual ranking or traffic changes should monitor Search Console and compare affected dates, queries, pages, devices and countries. It is also sensible to review indexing, security and manual-action reports before making major changes.
Immediate Checklist for Affected Sites:
Google advises sites affected by spam updates to review compliance with its spam policies. Automated systems may take time to recognise improvements, so businesses should avoid rushed changes or promises of immediate recovery. Google’s spam-update guidance
Current Position
Google’s September spam update is still rolling out as of 28 September 2026. The volatility over the weekend should be seen as a significant early indication, but we won’t see the full effect until Google confirms the rollout is complete.
We will keep a close eye on how things develop and provide additional updates and more detailed analysis as more information becomes available, so readers can stay informed about the update’s ongoing effects.
