If your rankings have felt jumpy since September, you are not imagining it. In about six weeks, Google rolled out a spam update, refreshed several technical documents and finished a worldwide release of its AI reports in Search Console. That is a lot for any site owner to keep up with.
We went through the latest announcements and documentation changes to separate what needs action from what is just noise. Here is what really matters for your SEO strategy and technical SEO this month.
The September 2026 Spam Update Is Still the Main Story
Google’s September 2026 spam update began in late September and, according to Search Engine Roundtable, was still moving through its phases in the first week of October. Spam updates go after manipulative tactics, so thin pages, scaled content and unnatural link patterns usually feel it first. We covered the early signals in our Google September 2026 spam update breakdown, and the advice still holds: let the rollout settle before you judge any traffic movement.
Recent comments from Google’s John Mueller add some useful context. He warned that programmatic SEO, meaning large sets of pages generated from templates and data lists, often ends up as spam, borderline spam or low-quality content. He also pointed out that once Google’s systems lose confidence in a site, winning that trust back takes time and real effort.
What to Check While the Update Settles
Look at Search Console by page type, not just across the whole site. Watch for template-based pages with very little unique value, near-identical location pages and old low-quality links pointing to your domain. Fix, merge or remove whatever is weak. Adding more pages on top of a shaky foundation rarely helps.
Technical SEO Updates Worth Knowing
Crawl Rate Documentation Now Explains Retry-After
On October 6, Google reorganised its documentation on reducing the crawl rate. The main addition is a clearer explanation of the Retry-After HTTP header. When a server returns a 503 or 429 status during an emergency, it can now tell Google’s crawlers when to come back, either as a delay in seconds or as an exact UTC date and time. Search Engine Roundtable notes that the underlying mechanism has not changed, because those status codes already told Google to slow down.
In practice, this matters if you are on shared hosting or planning a migration or server maintenance. A temporary 503 with a sensible Retry-After is far safer than letting pages time out. Google’s crawl rate guidance has long warned that leaving error responses in place for too long can make URLs drop out of the index, so think of it as a short-term tool only.
Page Experience and Structured Data
Google also added ad-related metrics to the Chrome User Experience Report and mentioned them in its page experience documentation. Google has suggested these are not a ranking factor, at least for now. Even so, it is a fair nudge to check whether intrusive ads or layout shifts are annoying real visitors. On the markup side, Google updated its video structured data guidance with a creator property, which is worth a look if you publish video.
Search Console Now Shows How You Appear in AI Features
As of August 31, 2026, Google’s generative AI performance report and AI controls are available to sites worldwide. The report sits as an expandable section under the main Performance report and shows impressions, pages, countries, devices and dates for AI features across Search and Discover. It does not show clicks or queries, and sites without enough data may not see it yet. Google’s own post on the generative AI performance reports explains the rollout in detail.
There is also a toggle that lets site owners opt out of their content appearing in or around AI features. For most local and service businesses, visibility is the whole point, so opting out rarely makes sense. Publishers with licensed content may see it differently.
Google has also added a multimodal search type filter and multi-select country filters to the Performance report. If you serve more than one market, such as India and the Gulf, comparing regions side by side is now much easier.

What Google's Documentation Says About Strategy
Google’s documentation changes this year all point the same way. The updated guidance stresses non-commodity content, meaning pages that offer something readers cannot find in a dozen near-identical articles. It also says that long-standing SEO best practices still support visibility in generative AI features. On October 1, Google refreshed its guide on using generative AI content to match the Search Quality Rater Guidelines.
That fits what we see in audits. AI-assisted drafting is fine, but unedited, mass-produced output with no original experience behind it is what gets filtered out. If you are trying to work out where SEO, AEO and GEO overlap, our post on how SEO, AEO and GEO work together breaks it down simply.
A Practical October Checklist
- Hold off on sweeping changes until the spam update finishes, and note the rollout dates against your Search Console trends.
- Audit thin and template-driven pages, then improve, merge or remove them.
- Make sure maintenance windows and server errors return a proper 503, ideally with a Retry-After header.
- Open the generative AI report in Search Console and note which pages appear in AI features.
- Strengthen your content with first-hand examples, named authors and data only you own.
Once the technical foundation is steady, the next step is growth. Our guide on how to increase website traffic in 2026 covers the practical side.
Frequently Asked Questions
Does the Retry-After header affect rankings?
No. It is a crawl signal that tells Google when to come back. It is not a ranking factor.
Is programmatic SEO banned?
Not outright. The risk comes from mass-producing pages with little real value, which Google’s systems can treat as low quality.
How long does it take to recover from a spam update?
There is no fixed timeline. Google’s own comments suggest recovery takes time and real effort, so focus on improving quality steadily.
Should I block AI features from using my content?
For most businesses looking for customers, visibility matters more. Publishers with paid or licensed content may reasonably decide otherwise.
Does technical SEO still matter with AI search?
Yes. Google’s documentation says established SEO best practices continue to support visibility in its generative AI features, and a site that cannot be crawled cleanly cannot be cited.
