Google’s September spam update is done: what changed for SEO
Google’s September 2026 spam update finished rolling out on 8th October after approximately 14 days, making it considerably longer than any of the three spam updates that completed earlier in 2026. For operators running sites with organic traffic, that end date matters: it gives you a fixed point to measure from.
What the update actually targeted
Google did not announce a new spam policy or name a specific tactic. The update improved its automated systems for detecting content and techniques that already breach existing policies. The practices those policies cover include:
- Large volumes of unoriginal content produced primarily to manipulate rankings
- Scraping and republishing content without adding value
- Doorway pages, keyword stuffing, and hidden text or links
- Cloaking and misleading redirects
- Site reputation abuse and expired domain abuse
- Hacked content
Google’s policies treat scaled content abuse as a function of purpose and value, not whether the content was produced by AI, human writers, or both.
Noticeable ranking movement was recorded around 25th to 27th September, 30th September, and 4th to 6th October. The final burst of volatility hit shortly before Google confirmed the rollout was complete.
How to assess your own exposure
Completion does not guarantee automatic recovery. Some ranking changes from this rollout may represent a new baseline rather than temporary noise. The smart approach is to segment your data rather than look at a single traffic percentage.
Compare performance before, during, and after October 8th, broken down by:
- Pages or sections with the steepest visibility drops
- Branded versus non-branded queries
- Commercial versus informational content
- Mobile versus desktop performance
- Rankings, clicks, and actual conversions
A site can lose visibility on low-value informational pages while its commercial traffic stays flat. The opposite is also possible. One headline number hides both scenarios.
Search Console now tracks visual search
Separately, Google introduced multimodal search reporting in Search Console. The new filter shows how pages perform when people search using images rather than typed queries. It covers searches made through Google Lens, Circle to Search on Android, images uploaded to Google Search, and Chrome’s “Search this image” feature.
The filter appears inside both the standard Search performance report and Google’s generative AI reporting. It only shows up if the site actually receives traffic from image-led searches, so not every property will see it immediately.
For retail, travel, property, food, design, and location-based businesses, this is a new data stream worth checking. Original images with accurate alt text and relevant surrounding copy are what drive this kind of discovery.
AI Overviews are showing more links
Google announced further changes to make sources more visible across AI Overviews and AI Mode. The updates include showing inline links higher within AI-generated answers, testing dedicated sections for important official pages, expanding article carousels for timely topics into more locations and languages, making related links more prominent with images, and testing clickable profiles for some creators and publishers.
Google described these as “continued and substantial increases” to inline link presence in its AI search experiences. That said, appearing as a source does not guarantee a visit. The useful metrics to track separately are: whether your brand is mentioned, whether your site is cited or linked, and whether that visibility actually produces traffic or conversions.
Clear, authoritative pages that answer questions directly and support claims with original evidence are what earn placement. Descriptive titles and headings help Google identify the most relevant page to surface.
