Daily Marketing News, October 2, 2026: YouTube will cut reach for reposted Shorts

This is Google's document on using generative AI content on your site. Google called the check "critical" and explained the reason directly: models don't find facts, they predict a likely sequence of words based on training data, so their answers can contain errors, known as hallucinations. The document was last changed in October 2025. Officially, Google simply aligned the documentation with what it has been saying at its developer events, while Search Engine Roundtable links the change to the spam update currently rolling out. For sites that publish AI texts at volume, this is a direct signal: pages without editorial review are at risk. Go through those pages and check numbers, dates, names and prices by hand.

A spam update is an algorithm change that demotes sites violating Google's spam policies. It was announced on September 24, the 1st wave hit sites on September 25, 26 and 27, and then the rankings started moving again on September 30. The difference from previous updates is the timeline: according to Google, this one rolls out over about 2 weeks, while the previous 3 spam updates took about 2 days, so there will be several spikes. Analyst Glenn Gabe noticed that AI translations of Reddit pages are climbing again in search results in Italy, Germany, Brazil, France and other countries. Site owners on forums report losing traffic from Discover, Google's recommendation feed, and from Google News. It's too early to draw conclusions from a single day: if you count 2 weeks from September 24, the rollout ends around October 8, so compare rankings after that date.

AI Overviews is the block with an AI answer above the regular Google results. Before, a search with a brand name usually showed the company's site and navigation elements. Now, according to the publication, an AI answer appears for almost any major brand, with the only exceptions being Google's own name and news publishers. On the same day, DemandSphere published an analysis: the number of AI Overviews for brand searches grew 3 times in September. Google also started generating these answers for searches about sports team rosters. For a company, this means the first thing a person sees after typing its name is more and more often written by AI, not by the website. Check your brand in Google: if the answer has errors, update the facts on your site and in your Business Profile.

The help page covers the "Destination not working" policy: an ad gets disapproved under it if its link doesn't open. Google added new examples of link problems and a line about campaigns with asset groups. An asset group is a set of texts, images and videos from which Google assembles ads itself, mainly in automated Performance Max campaigns. The new line requires at least 1 configured asset group in the campaign, otherwise "invalid final URL" can appear during setup even when the site loads. Before, this case wasn't described in the help center, and advertisers went looking for a problem on their site. If you see this error, first check whether the campaign has a configured asset group.

Microsoft Advertising is Microsoft's ad platform, which shows ads in Bing search and on partner sites. According to Search Engine Roundtable, experiments are available for Search, Shopping, Audience and Performance Max campaigns. They work as a controlled A/B test: part of the traffic runs on the campaign's old settings, part on the new ones, and the system compares the results. Until October 1, the feature was in testing; now it's open to everyone for these campaign types. The benefit is simple: you can test a change in bids or bidding strategy on part of the traffic without risking the whole campaign. If you run ads on Bing, put every major change through an experiment before switching the entire campaign.

Local Services Ads are ads for local services such as plumbers, lawyers or repairs, with pay per lead and business verification by Google. The advertiser sets the cities or areas they serve and pays for each call or request. Judging by the reports, Google is showing ads outside these zones, so a business may be paying for calls from areas it doesn't serve. Google hasn't confirmed the bug yet. If you run these ads, compare the addresses in recent incoming leads with your service area and save a list of calls from outside it: that gives you something concrete to take to Google support.
