Search in October 2026: six changes, and which ones need you

October was a busy month for search, and most of it wasn’t about the ten blue links. Google changed how its AI answers link out, rewrote what businesses can say on Maps, built a fast lane for forum posts and put a shopping cart inside Search.

Here’s each change with one line on what to do about it. Things only a handful of people have seen are at the bottom, marked as tests.

1. Google’s AI answers are getting more links

What happened. On 15 October Google announced five changes to AI Mode and AI Overviews. More inline links, shown higher up in answers. A test of a dedicated section at the top for official sites, for when there are “only one or two official places on the web to complete a specific task”. News carousels rolling out to more countries and languages. Bigger related links with image thumbnails at the end of some answers. And a test of clickable creator names on video results.

Google also said the number of people using its Preferred Sources feature has grown more than seven times since the start of the year.

What to do. Make the page that completes each task on your site (book, get a quote, see prices) obviously that page. I’ve gone through all five changes in a separate guide.

Verdict: act.

2. The September spam update took almost two weeks

What happened. Google’s status dashboard lists the September 2026 spam update starting on 24 September and running for 13 days and 16 hours, so it finished around 8 October. For comparison, the June and August spam updates each took under three days. The last core update was in May.

What to do. If your traffic dropped between 24 September and 8 October, read Google’s spam policies before you change anything else. A spam update is a different problem from a core update, and the fixes are different too.

Verdict: check, if your numbers moved.

3. New rules on what businesses can put on Google Maps

What happened. Google rewrote the advertising section of its Maps content policy, and Search Engine Roundtable reported the change in early October. Your listing can no longer carry “time-bound promotions, pricing, or direct calls-to-action”. Your posts can’t carry contact details or links that aren’t related to your business, though offers are still allowed in posts.

What to do. Read your Business Profile description today. If it says “20% off this month” or “call now”, move that to a post. There’s a ten-minute checklist here.

Verdict: act this week.

4. Google built a fast lane for forum posts

What happened. Google published documentation for a UGC Fresh Data Program (the page was last updated on 8 October). Approved platforms can push user-generated content and engagement counts straight to Google through a dedicated pipeline, separate from normal crawling. It’s only open to large platforms with public, moderated discussions, and Google says it “doesn’t guarantee that content will appear in Search”.

What to do. Unless you run a big forum, there’s nothing to apply for. What it tells you is where Google is putting effort: getting fresh discussion into Search quickly. A thread about your business could show up faster than it used to, so search your name on Reddit and the forums in your industry once a month, and answer honestly as yourself.

Verdict: watch.

5. Universal Cart arrives in the US

What happened. Also on 15 October, Google launched Universal Cart in Search and the Gemini app in the US. Shoppers can save products from different stores in one cart, get alerts when prices drop or items come back in stock, and check out through Google Pay or on the retailer’s own site.

What to do. If you sell online in the US, a shopper can now park your product in Google’s cart and come back when the price drops. Make sure the prices and stock Google shows for your products are right. Outside the US, nothing to do yet.

Verdict: check, if you sell in the US.

6. Business Home enters a closed beta

What happened. Google’s help centre now describes Business Home as “a growth partner built with Gemini models” that connects a business’s Google tools in one place. It’s a closed beta for selected business categories in the US and UK. Google says it will spot real-time demand surges and help publish seasonal offers.

What to do. Nothing. You can’t sign up. It’s worth knowing the direction, though: Google wants to be the place a small business runs its whole online presence from.

Verdict: watch.

A number going round

Search Engine Roundtable reported data from Semrush, SE Ranking and seoClarity showing AI Overviews on over 80% of Google searches, up from about 50% in June 2025. Treat the exact figure carefully. Each tool tracks its own set of keywords, and those sets aren’t your customers’ searches. Search the twenty queries that actually bring you enquiries and see what shows up for them.

Tests to ignore for now

• New ChatGPT ad formats. A few people have seen ChatGPT ads with a “Learn more” link, and one marketer says some are being bought through Amazon’s ad platform. OpenAI hasn’t announced anything.
• A rebuilt Business Profile performance report. Two people sent screenshots of a new report with reviews, search trends and recommendations. Nobody else has seen it yet.
• Ranking swings from 20 to 24 October. Plenty of chatter, no confirmed update. Don’t change anything because of it.

That’s October. Which of these is actually showing up in your numbers?
