What to Check After Rollout Copier
Google’s September 2026 spam update is officially complete. According to the Google Search Status Dashboard, the rollout began on September 24 and finished on October 8, 2026. Google stated that the update applied globally and across all languages.
If your organic traffic changed during that period, now is the time to compare affected pages and query groups. It is crucial to diagnose patterns rather than react to a single day of ranking volatility.
When did the update run?
Google recorded the spam update as beginning on September 24, 2026, at 09:15 Pacific Time and ending on October 8 at 01:00 Pacific Time. This timeline provides site owners with a clear window for comparing Search Console performance.
What should you check first?
- Compare before and after the rollout. Analyze clicks, impressions, average position, and landing pages.
- Separate sitewide drops from page-level drops.
- Review search intent. Google may prioritize different types of pages.
- Inspect indexability. Technical issues can coincide with algorithm updates.
- Look for patterns in weak content. Pages primarily designed to capture query variations should be reviewed.
Do not assume every decline is a penalty
A ranking drop during a spam update does not necessarily indicate a manual penalty. Algorithmic systems can reassess pages without issuing a manual-action notification. Additionally, technical problems such as noindex tags, canonical changes, 5xx errors, or internal-link modifications can lead to traffic losses that coincide with an update.
Utilize the Noindex & Indexability Checker and Canonical Tag Checker to eliminate basic technical issues before making extensive changes to the site.
What kinds of pages deserve the closest review?
Prioritize pages that exhibit a combination of significant traffic loss and weak differentiation. Common warning signs include mass-generated near-duplicates, thin affiliate pages, misleading functionality, or content primarily targeting slight keyword variations.
AI-assisted content is not inherently problematic. The key consideration is whether the final page provides users with trustworthy and distinct information, such as firsthand experience, original analysis, useful tools, data, clear comparisons, or genuinely better explanations.
Use a page-level audit
If only a subset of pages experienced declines, refrain from making sitewide changes immediately. The SEO Website Analyzer can assist in checking titles, descriptions, headings, canonical tags, robots.txt, and schema while you manually compare content quality.

How to Compare Your Traffic Before and After the Update
In Google Search Console, open Performance > Search results and compare two equivalent periods before and after the September 24–October 8 rollout. Avoid treating the rollout period itself as a clean baseline.
- Compare organic clicks and impressions.
- Identify pages with the largest changes.
- Filter by queries to check whether search intent or visibility changed.
- Compare countries and devices to identify affected segments.
- Check whether changes overlap with technical errors, content updates or seasonal trends.
Use complete reporting dates and allow time for Search Console data to stabilize. A traffic decline during the rollout does not, by itself, prove that Google’s spam systems caused it.
