5 Marketing Trends: Week of October 12, 2026
If you run a small business, here is the uncomfortable part of the week of October 12, 2026. Customers keep asking Google and ChatGPT for answers, and those tools decide whose name comes back. Sometimes that is yours. Often it is a bigger company with a bigger website. Google's AI summaries now sit on most brand name searches. Google wants a person to check every AI-written page before it goes live. AI shopping answers lean toward the big chains. ChatGPT is adding image ads and better measurement. And Performance Max finally lets you test creative the clean way. Five stories from Search Engine Land, published between September 30 and October 5, cover all of it. Here is what each one means and what I would do about it this week.
What are the top marketing trends for the week of October 12, 2026? The top marketing trends for the week of October 12, 2026 are AI Overviews on brand name searches, Google's manual fact-check warning for AI content, AI shopping answers that favor big retailers, ChatGPT Ads with visual formats and measurement, and A/B testing in Performance Max.
What you will learn
- Why Google AI Overviews now appear on most brand name searches, and the five minute check that shows what yours says
- What Google changed in its guidance on AI-written content, and the one word that matters
- How AI shopping answers pick winners, and the single word that put small stores back in the results
- What OpenAI added to ChatGPT Ads, and why I would watch it before spending a dollar
- How to run a clean A/B creative test in Performance Max before the holiday rush
- The thread that connects all five
1. Google AI Overviews now show up on most brand name searches
Source: Search Engine Land
Search your own business name on Google. Go ahead, I will wait. If an AI-written summary sits above the usual links, you just saw the biggest search story of the week.
DemandSphere tracks branded queries every day, and its data shows AI Overviews on more than 80% of them by late September. At the start of the month that number sat near 26%. For most of September it hovered between roughly 27% and 35%. Then it jumped to 69% on September 26 and peaked at 90.48% on September 27. It was still at 82% on September 29. Google has not announced anything that explains it.
A second test points the same way. Chris Long at Nectiv checked 100 enterprise brands and found AI Overviews for 93 of them, plus some smaller companies. Here is the catch, and it matters. Neither study measured clicks, so nobody knows yet whether people click less on brand searches. DemandSphere also counted any AI Overview that appeared, whether or not it mentioned the brand.
What I would do: open a private window, search your business name, and read the summary like a stranger would. Check your hours, phone number, address, and services. Something wrong? Fix it where the AI probably got it, which is usually your website, your Google Business Profile, or a directory listing. Our guide to checking your AI search visibility walks through the rest.
- AI Overviews appeared on more than 80% of tracked branded queries by late September, up from about 26% at the start of the month, according to DemandSphere.
- Nectiv's test found AI Overviews for 93 of 100 enterprise brands, and for some smaller companies too.
- Click impact is still unknown because neither study measured clicks.
- Search your own brand name and fix any wrong facts at the source.
2. Google says to manually fact-check all AI-written content
Sources: Search Engine Land and Google Search Central guidance
Google edited one of its help pages this week, and one word in it deserves your attention. The page covers using generative AI content on your website. Google added a plain explanation of the problem. These tools do not look up facts. They predict a likely string of words based on their training data, so they sometimes get things wrong. Google's own name for those errors is hallucinations.
Then came the line that matters. Google now says it is critical to manually fact-check and review all AI-generated content for accuracy and trustworthiness before you publish it. Google said it made the change to bring its documentation in line with the presentations it gives at developer events.
Search Engine Land connected this to the September spam update that is still rolling out, which may be aimed at some mass-produced content, including AI pages nobody reviewed. That link is Search Engine Land's read, not something Google confirmed. I covered the update itself in last week's trends post.
My take is simple. Whoever drafts it, a person signs off on every fact. Check each number against its source. Check names, dates, prices, and anything about your own services. Keep a short list of where each claim came from. It takes longer than hitting publish, and it is the reason your pages can earn a spot in AI Overviews instead of getting skipped.
- Google's help page on generative AI content now calls manual fact-checking and review critical before publishing.
- The page explains that generative models predict likely words instead of retrieving facts, so errors happen.
- Search Engine Land links the change to the ongoing spam update, but that is its interpretation, not Google's statement.
- Verify every statistic, name, date, and price in anything AI helped draft, and keep your sources.
3. AI shopping answers lean toward big retailers over local shops
Source: Search Engine Land
A new study of nearly half a million AI answers backs up what a lot of shop owners already suspect. When shoppers ask ChatGPT or Google where to buy something, the big chains win. Vaer AI ran the study for Lightspeed Commerce, a retail software company, so keep that in mind. The numbers are still hard to ignore.
With web search turned off, ChatGPT and Gemini recommended large national chains 63% to 70% of the time. Small or local independents showed up about 10% of the time. Given one big retailer and one small store with no size labels, the models picked the big one 90% to 94% of the time. Turn live search on and large retailers still held the top spot in 46% to 58% of answers across ChatGPT, Google AI Mode, and AI Overviews.
Specific searches made it worse. For a broad request like toys for a 6-year-old, small stores got about a third of the top recommendations. Name an exact product and their share dropped to about 10%.
Now the useful part. Adding the word independent to the prompt more than doubled how often small and local stores were named, from about a third to nearly four fifths in a sample of the study's prompts. The words local and near me did far less, partly because AI can count a nearby branch of a national chain as local.
So say it on your own pages. If you are independent, family owned, or locally owned, use those exact words on your About page, your Google Business Profile, and your product pages. Name the products you carry, with prices and stock. The study tested prompts, not website wording, so treat that as a smart bet and not a proven fix.
- Without web search, ChatGPT and Gemini named large national chains 63% to 70% of the time and small independents about 10%.
- With live search, large retailers were the top pick in 46% to 58% of answers.
- Adding the word independent to a shopping prompt more than doubled small-store recommendations, while local and near me did much less.
- Use independent or locally owned on your site and profile, and list specific products with price and stock.
4. ChatGPT Ads add visual formats and better measurement
Source: Search Engine Land
OpenAI is building out ChatGPT Ads, and this week's update was about two things. Pictures and proof. The new visual ad format shows products, services, and experiences through images. Testing starts later this month with a group of U.S. advertisers, first during image generation in ChatGPT. The ads will be labeled and kept separate from the images ChatGPT creates.
The proof part is measurement. OpenAI added Hightouch, Tealium, and LiveRamp to help advertisers send conversion data in, plus a long list of attribution partners including AppsFlyer, Triple Whale, Northbeam, and Kochava. Haus, Measured, and WorkMagic are exploring geo-based experiments that test whether the ads cause extra sales or just get credit for them. DoubleVerify and Integral Ad Science are working on brand suitability pilots.
OpenAI says ChatGPT reaches 1.2 billion people a week. It also shared early partner results. One partner measured WeightWatchers' attributed cost per acquisition at 15.3% below its blended paid search benchmark. Another found 67% of incremental purchases for the brand Dose came from new customers, and a third reported that 93% of Portland Leather's visitors from the ads were new. Those are early, partner-reported numbers, not platform-wide benchmarks.
Should a small business jump in? I would watch, not spend. The article does not say who can buy in or what it costs, and the testing group is limited. What you can do now is the boring prep. Make sure your conversion tracking works and your customer list is clean, because every channel on this list will ask for both.
- OpenAI announced visual ads for ChatGPT, with testing among a group of U.S. advertisers beginning later this month.
- New measurement partners include Hightouch, Tealium, LiveRamp, AppsFlyer, Triple Whale, and Northbeam.
- The early results came from partners, not from platform-wide benchmarks.
- Fix your conversion tracking now, then decide whether the channel is worth a test.
5. Performance Max finally gets A/B testing for creative
Source: Search Engine Land
If you run Google Ads, here is the most practical item of the week. Google is rolling out A/B testing for Performance Max asset groups. You can now test changes to headlines, descriptions, images, and videos against what you already have, instead of swapping everything out and guessing what moved the numbers.
Search Engine Land lists a few fair fights. A new creative idea against your current one. UGC-style content, the kind that looks like a customer made it, against polished brand creative. Different messaging or image styles, or the effect of adding or changing a video. There is one catch. Once a test starts, you cannot edit that asset group until it ends. That rule keeps the results clean, so plan the test before you launch it. Paid search specialist Bia Camargo spotted the rollout first, which means you may not see it in your account yet.
Holiday timing makes this worth doing now. Pick one change. Just one. Run it before the busy weeks so you walk in knowing which creative earns its spot. And do not expect the test to open up the whole black box. It answers one question, which is whether that creative change helped. If you want help setting up tests like this, that is part of our performance and offer strategy work.
- Google Ads is rolling out A/B tests for Performance Max asset groups covering headlines, descriptions, images, and videos.
- You cannot edit the asset group while a test is running.
- Test one change at a time, such as UGC-style content against polished creative.
- Start before the holiday rush so you have an answer when spending peaks.
The through line for the week
Step back and the five stories share one thread. Machines are deciding more of what customers see, and the businesses that get named are the ones whose facts are right and easy to read. AI Overviews are answering brand searches. Shopping tools lean toward the biggest names. Google wants a human to check AI content before it goes live. Even the ad platforms are asking for cleaner data and cleaner tests.
That is good news for a small business, honestly. You can't outspend a national chain. You can be more accurate, more specific, and more yourself than they are. Say plainly who you are and where you are. Keep your hours and details current everywhere. Check what the AI says about you. Test one thing at a time. Our post on why customers can't find you online covers the basics.
If you want the bigger picture, start with how GEO works. And if you want someone to look at where you stand, that is what our generative engine optimization work is for.

Book a callFrequently asked questions
What are the top marketing trends for the week of October 12, 2026?
The top marketing trends for the week of October 12, 2026 are Google AI Overviews appearing on most brand name searches, Google calling manual fact-checking of AI-written content critical, AI shopping answers that favor large retailers, ChatGPT Ads adding visual formats and measurement partners, and A/B testing arriving in Google's Performance Max.
Why does Google show an AI summary when I search my business name?
DemandSphere data shows AI Overviews on more than 80% of tracked branded queries by late September, up from about 26% at the start of the month. Google has not explained the jump. Search your own name in a private window, read the summary, and correct any wrong hours, phone numbers, or services at the source, such as your website, Google Business Profile, or directory listings.
Can I use AI to write my website content?
Yes, but Google now says it is critical to manually fact-check and review all AI-generated content for accuracy and trustworthiness before publishing. Generative tools predict likely words instead of retrieving facts, so they can get things wrong. A person should verify every statistic, name, date, and price before the page goes live.
How do I get AI tools to recommend my small business instead of a big chain?
A Vaer AI study run for Lightspeed Commerce found that adding the word independent to a shopping prompt more than doubled how often small stores were named, while local and near me made less difference. Use words like independent and locally owned on your site and Google profile, and list specific products with prices. The study tested prompts, not website wording.
Is it worth testing ChatGPT Ads or Performance Max creative this fall?
Performance Max A/B testing is the easier call if you already run Google Ads, because you can test one creative change before the holidays. ChatGPT Ads are still in limited testing with a group of U.S. advertisers, and the early results come from partners. Fix your conversion tracking first, then decide.
