Late in August the website of the American tax service dropped out of Google. Not a few pages. The whole site, gone from the index, at the exact moment people were searching for it. There was no penalty behind it and no algorithm update. Somebody had changed a bot setting.
That one incident explains most of what August was really about. Search stopped being something you win with content alone and became something you can switch off by accident. Here is what changed last month, what has happened since, and what you should be doing about it in September.
The three biggest changes
A security setting can now take you out of Google
Cloudflare sits in front of a very large share of the web, including a lot of South African sites. It sorts the bots that visit you into categories. The trouble is that Googlebot is not only a search crawler. Cloudflare now files it as Search plus Training, because Google uses the same crawl to feed its AI products. So when you tell Cloudflare to block AI training bots, you can block the crawler that indexes you for search at the same time.
That is what took the tax site down. It is also the most likely explanation for PDFs across a range of sites falling out of results in the last week of August.
Here is the part that was not clear when we first covered this on 13 August. From 15 September, Cloudflare’s new defaults apply to new customers, to new sites added by existing customers, and to every existing free plan customer. If you pay for a configured Cloudflare zone, nothing happens to you on the fifteenth. If you are on the free plan, it happens to you automatically.
Why this matters for your business: most small business sites in South Africa run Cloudflare on the free plan, usually set up years ago by whoever built the site. Open your Cloudflare dashboard, find the AI Crawlers and Scrapers settings, and read what is actually set to block. If Training is blocked on pages that carry ads, Googlebot goes with it. Check this before the fifteenth rather than after your traffic falls over.
Google will move your ad campaigns for you this month
Google is retiring Dynamic Search Ads. From September you can no longer create a new Dynamic Search Ads campaign in Google Ads, in Google Ads Editor or through the API. Eligible campaigns using automatically created assets or campaign level broad match get migrated to AI Max through September, with no opt-in and no opt-out. Existing Dynamic Search Ads campaigns hold on until February 2027.
The reason this belongs in a monthly recap rather than a daily brief is the second half of the story. Lunio examined 414 million retail clicks between October 2025 and June 2026 and found that search campaigns running AI Max carried 72 percent more invalid traffic than standard search campaigns. The invalid traffic rate on AI Max more than doubled, from 2.46 percent to 5.28 percent, while standard campaigns improved from 3.72 percent to 3.07 percent over the same period. AI Max accounted for 68 percent of every invalid click Lunio detected across Google search.
Why this matters for your business: you are about to be moved onto a product with a measured waste problem, weeks before your busiest trading quarter. Log in this week and list every campaign using automatically created assets or campaign level broad match, because those are the ones that move. Build out your negative keyword list before the migration rather than after it. Read your search terms report weekly through September, and compare your cost per lead in the second week of the month against your August figure.
The AI answer stopped asking permission
Google confirmed on 28 August that AI Overviews now expand on their own for some searches. The Show more button disappears, the full answer loads, the Ask anything box appears underneath it, and your ordinary listing moves further down the page. Google would not say what share of searches this affects.
Set that against the figures we opened the month with. Zero-click searches reached 68 percent of United States queries in early 2026, up from roughly 60 percent in 2024. Where an AI Overview appears, the click-through rate on the first organic result drops sharply.
Why this matters for your business: a position one ranking is worth less than it was a year ago and that trend is not reversing. The answer is not to walk away from search. It is to stop measuring rankings alone. Track how often you appear as a cited source inside AI answers. Put your prices, opening hours, service areas and direct contact details on the page as plain readable text so they can be pulled out and quoted. And give more weight to the channels you actually own, which means your email list and your repeat customers.
What turned out to be noise
Three things looked alarming in August and turned out to be nothing.
Search Console impressions for generative AI surfaces collapsed in the middle of the month and plenty of people assumed they had lost visibility overnight. It was a logging fault. Google’s data anomalies page now scopes it to 13 to 17 August.
Favicons disappeared from search snippets. Google’s VP of Engineering for Search confirmed the fault sat on Google’s side, and it was fixed by 23 August.
PDFs stopped ranking in the final week. John Mueller acknowledged it publicly and the affected PDFs were ranking again by 27 August.
The pattern is worth keeping. When something breaks across many unrelated sites on the same day, it is almost always a bug rather than a penalty. Give it 48 hours and check whether anyone else is seeing it before you start rebuilding pages.
Automotive
Vehicle listings changed route, they did not disappear
Google has stopped supporting structured data markup as a way of powering the Vehicles for Sale display inside a dealer’s Google Business Profile. A fair amount of coverage read that as Google killing free vehicle listings. It has not. The feed based Vehicle Listings programme carries on. What has gone is the shortcut where a dealer relied on markup embedded in their own website to get inventory showing on Google.
That sits alongside two other August changes worth knowing. Merchant Center performance report definitions changed on 24 August and the restatement was backdated to 1 July, so any year on year comparison you pull today is quietly measuring two different things. And Google split the generic Auto repair and Auto body categories in Local Services Ads into specific service categories, which changes who you compete against on a service booking search.
Why this matters for your dealership: ask your website provider one direct question this week. Are our vehicles reaching Google through a Merchant Center feed, or through markup on the site? If the answer is markup, your listings are on the way out and you need a feed instead. While you are there, write the 1 July restatement date on your Merchant Center reports so nobody in the business misreads a definition change as a drop in performance. On the local picture, naamsa put July at 57,708 new vehicles sold, up 11.9 percent year on year, with the first half of 2026 up 12.9 percent. August figures land in the first week of September.
Still unresolved
Four things go into September genuinely open.
Google’s video carousel has largely vanished, with the feature falling from over 30 percent of tracked brands to around 5 percent. Google separately ended support for video carousel structured data, but has never publicly connected the two.
Google has said nothing at all about the AI Max invalid traffic findings.
Recovery from the August spam update has not arrived for most affected sites. Google says recovery takes months. Practitioners report four to eight weeks, which puts the earliest realistic movement in the second half of September.
And nobody yet knows what Cloudflare’s 15 September defaults will do to real free plan sites once they are actually live.
What to do this month
- Open Cloudflare before 15 September and read what your AI crawler rules actually block.
- List every Google Ads campaign using automatically created assets or campaign level broad match, because those migrate to AI Max this month.
- Rebuild your negative keyword list now rather than after the migration lands.
- Confirm whether your vehicle or product inventory reaches Google by feed or by markup.
- Stop treating a same day drop across many sites as a penalty, and look for a reported bug first.
- Update Elementor Pro to 4.2.2 or later and WP Rocket to 3.23.3.3 or later, and regenerate any Cloudflare or Sucuri keys you had stored in WP Rocket.
September is going to be a busy month for anyone running a website or a Google Ads account. If you would rather have someone watching this for you, talk to us and we will take a look at where you stand.
