Daily Marketing News, October 9, 2026: Google Finished the September Spam Update
Google finished its September spam update. It took almost 2 weeks instead of the usual 2 days, and at the same time consultants noticed more manual actions. OpenAI gave GPT-6 to free ChatGPT users, and starting October 21 YouTube is letting online casinos onto the biggest banner on its home page.
Story of the day: Google finished the September spam update and is penalizing sites by hand more often
On October 8, 2026, Google announced that the September spam update had fully rolled out. A spam update is an algorithm change that pushes down sites that break Google's spam policies. The note appeared on the Google Search Status Dashboard at 01:37 Pacific time: "The rollout was complete as of October 8, 2026". Updates like this usually wrap up in 2 days. This one took almost 2 weeks.
People disagree on exactly when it started. Search Engine Roundtable counts from 12:00 Eastern time on September 28, 2026, and puts the end at 4:37 Eastern time on October 8. Relevant Audience takes September 24 as the start and counts 13 days and 16 hours. When checking your own site, use the earlier date. If you count from September 28, the opening 4 days of volatility land in your "calm" period and blur the comparison.
You can see how hard the results were shaken in data from Diib, cited by Search Engine Journal. Across 32,569 sites, the median share of visits from organic Google search dropped from 34% to 31%, based on data for September 24 and 26, 2026. That's a 3 percentage point difference. For a typical site in the sample, it means the organic share shrank by roughly 9% of what it was.
On the same day, October 8, reports surfaced that Google has been issuing manual actions more often. A manual action is a penalty applied to a site by a Google employee rather than by the algorithm. Consultant Marie Haynes wrote that she now gets "several a week" requests for help with manual actions, when before it was almost zero. There are 3 reasons: thin content, outright spam, and mass generated content. The last one looks uncomfortably like the way a lot of people fill their sites with AI these days.
There's just one piece of good news: there won't be any new waves of this update, so you can make an honest before and after comparison. Compare your organic traffic from Google for the 2 weeks before September 24 with the 2 weeks after October 8. If there's a drop, open the Manual actions section in Search Console first. The algorithm and a Google employee penalize sites differently, and fixing the damage works differently too.
More news for October 9, 2026
ChatGPT, OpenAI's chatbot, had previously offered the new GPT-6 generation of models only to paying subscribers. Now the Free and Go plans get it too, running on the GPT-6 Luna version. The paid Enterprise, Business, Pro, and Plus plans run on GPT-6 Sol and got the update a day earlier, in the Chat tab. Along with the model came a format called Intelligent UI: instead of a wall of text, an answer can include buttons, charts, forms, or a small working tool. According to OpenAI, on questions that involve web search, GPT-6 Instant starts answering 44% sooner on average than GPT-5.6 Instant. More than 1.2 billion people use ChatGPT every week. The model now draws comparisons and tables on its own, and it has an easier time pulling data from sites where prices, specs, and product comparisons sit in tables and lists rather than being spread across paragraphs.
UGC is content created by users themselves: posts and threads on forums. Until now Google found these pages mostly through regular crawling, whenever its bot got to them. Now approved platforms pass content and engagement signals directly. The requirements are strict. Content has to be submitted as fast as possible, ideally within a few minutes of posting, and engagement counts have to be updated regularly for 72 hours. Pages must be public: content that requires a login or payment to view doesn't qualify. On the technical side you need OAuth 2.0, JSON-LD, and markup such as DiscussionForumPosting. Google promises to respond to applications within 6 to 8 weeks and doesn't guarantee placement in results. For forum and community owners, this is a chance to show up in Search while the discussion is still fresh.
AI Max is a set of AI settings for Google Ads search campaigns: Google expands queries and writes ad copy on its own. Previously you could only see the generated headlines and descriptions after turning on the text customization setting. Now you just enter a final URL: Google analyzes the landing page and in about 30 seconds shows up to 10 examples of AI headlines and descriptions. The preview lives in the Asset optimization section and is available when creating a search campaign or editing an existing one. It works in every language where text customization is available and in most business categories, except adult content. Search Engine Land reported it. One caveat: these are examples, and Google won't necessarily show exactly these in your ads. But if the examples promise a discount you don't offer, that's what the model is reading from your page.
The tool is built for retail media. That's advertising brands buy from retailers and marketplaces, based on data about those retailers' shoppers. Now a retailer or marketplace can pass its audience segments to brands and sellers running eligible retail media campaigns. To do that, the retailer links its Google Ads account to the relevant Merchant Center and data sharing accounts, and both sides have to meet Google's requirements. The brand sees segment names, customer types, and conversion data. The main limitation: these audiences only work in commerce media network campaigns. You can't add them to regular Search, Shopping, or Performance Max. Search Engine Land reported it.
An experiment in Google Ads is an A/B test: part of a campaign's traffic goes to a modified version, and then the 2 versions are compared. Previously you had to dig through the metrics table by hand. Now the Summary tab has an AI panel: the experiment goals, 2 key findings with recommendations, and 3 suggested questions that open the Ask advisor assistant. Google also clarified what happens when you apply Performance Max experiments, Google's automated campaigns across all of its placements. In migration experiments, traffic moves fully to Performance Max. In optimization experiments, the tested settings are applied permanently. In custom experiments, you pick the winning version by hand. The key word here is "permanently": before you hit apply, look at the raw numbers, not just the 2 AI findings. Search Engine Land reported it.
One change concerns conversion paths, the chain of ad touchpoints before a purchase. Video impressions now show up there, marked with an eye icon. Previously video only counted in these paths through views. The other change is a new Performance by stage card that splits metrics across 3 funnel stages: awareness, consideration, and action. It includes impressions, CPM (the cost of 1,000 impressions), frequency, views, and video view rate. If you've set up Brand Lift, Search Lift, and Conversion Lift studies, their data goes into the card too. The limitations: video impressions in paths count only for eligible web conversions, and conversions imported from Google Analytics 4 aren't counted. If you measure results through GA4, the new summary will give you an incomplete picture. Search Engine Land reported it.
Until now the Masthead was open to sports betting but closed to most other kinds of online gambling. Google published the notice on October 7, and Search Engine Land covered it on October 8. Advertisers have to be certified under Google's gambling policies and comply with the law as well as geographic and age restrictions. Those who promote gambling related content but aren't subject to mandatory government licensing of gambling operators still won't be allowed into the format. For everyone else, it means more competition for the most visible spot on YouTube. If you were planning a Masthead for late October, keep in mind that casinos are now in the running for that spot too.
AdMob is how developers earn money by showing ads inside their apps. The bug hit interstitial video ads, the ones that cover the whole screen. The video doesn't load, a black screen appears instead, the close button doesn't respond, and the user can't get back to the app. The problem affects both iOS and Android. Google says there's no workaround yet, the app has to be force closed, and no fix date has been given. Search Engine Land reported it. A person stuck on a black screen doesn't blame Google, they blame the app. App owners should watch uninstalls and fresh reviews, and maybe reduce the share of interstitial video while the bug lasts.
Merchant Center is the account online stores use to upload products to Google Shopping and Shopping ads. The new wording says such a product may be "disapproved instead of updated if a mismatch is detected". That warning wasn't in the help docs before. A mismatch usually means a discrepancy between the feed (the product file sent to Google) and the website, for example in price or availability. Search Engine Roundtable spotted the change. It hits hardest for stores with dynamic pricing, where prices are recalculated several times a day. If the feed lags behind the page, the product risks dropping out of ads. Check price and availability in the feed and on the page after every change, not once a day.
A carousel is a post made of several slides. Previously Edits worked only with videos. Now you can combine photos, videos, and text on a single canvas and edit them with the app's tools. A finished carousel can be published straight to Instagram or downloaded for other platforms. The feature is on iOS only for now; Android will get it later. Social Media Today broke the news on October 7, and Storyboard18 and Social Samosa picked it up on October 8. For creators, this means videos and carousels can now be made in one app with a consistent style.
What site owners, advertisers, and stores should do
- Once you have 2 weeks of data after October 8, that is by October 22, compare your Google traffic with the 2 weeks before September 24. Right now, open the Manual actions section in Search Console.
- Before turning on text customization in AI Max, open the preview and check all 10 examples. Look for inaccurate promises, wrong prices, and phrases that don't sound like your brand.
- Treat the AI insights in Google Ads experiment reports as a hint and check them against the raw numbers, especially before applying Performance Max optimization experiments. In the funnel card, remember that GA4 conversions aren't counted.
- If you run a forum or community with a large audience, check whether you qualify for the UGC Fresh Data Program: you need public pages with stable URLs and DiscussionForumPosting or SocialMediaPosting markup. Apply early, since the response takes 6 to 8 weeks.
- Stores whose prices change more than 1 time a day should set up a check that the feed and the product page match after every change.
