Both are useful, but all channels default to high priority, so nothing changes unless you change it. [Notebook](https://dumbcmo.com) › [Blog](https://dumbcmo.com/blog) › Paying to be seen › Google Ads: new spending controls and a 1-click AI Max test You hand Google $25 a day and say, “spend it well”. Google spends some of it on places you’ve never heard of. This month it handed you a few dials. ## In normal-people words Two Google Ads updates reported in October 2026: **1. Channel prioritization and budget allocation** (Search Engine Journal, 14 October). You can mark channels as **High priority** or **Low priority**. Google funds the high-priority ones first. You can also cap how much of your daily budget lower-priority channels get, and 0% blocks a channel. Google says limits are “best-effort”, so they aren’t hard caps. It works for Search, Shopping, Performance Max and Demand Gen, with differences. In Search you can prioritise channels like Search Partners and Display separately. In Performance Max and Demand Gen, Google’s own channels (Search, YouTube, Discover, Gmail, Maps) are grouped. It’s rolling out globally over the coming months. **2. 1-click AI Max experiment** (Search Engine Roundtable, 26 October). Eligible accounts may see a recommendation that sets up a 50/50 test of your normal Search campaign against an AI Max version. AI Max adds options like broader search term matching and automatic asset optimisation. > **The DumbCMO:** Google gives you a dial after spending your money for years. Take it. Then read the small print on the dial. ## The catches **What it means for you** - **If** You run Search ads and see spend on Display or Search Partners **→ then** You can finally mark them low priority or give them a small share. - **If** You use Performance Max **→ then** You can’t split Google’s own channels from each other, only group them. - **If** Google shows a 1-click AI Max test **→ then** It’s a fair test, but it’s Google suggesting a Google product. Check results on your own sales, not Google’s dashboards alone. Two details worth knowing: every channel defaults to high priority, so you must change settings yourself. And in February 2027 Google retires the old Search-over-Display allocation setup. To keep the same behaviour, Google suggests Display set to low priority with a 50% allocation, with a one-click migration planned. ## The chai stall version Your helper buys tea leaves, sugar and milk from five shops. You tell him, “milk from the dairy first, other shops only if they’re cheaper.” **That’s all channel priority is. You’re telling Google where to shop first.** ## Do this today - [ ] In Google Ads, open your Search campaign’s channel or network report and see how much went to Search Partners or Display. - [ ] If that spend produced no sales, plan to set it to low priority when the control shows up on your account. - [ ] If you see an AI Max recommendation, don’t click it yet. Note your current cost per sale first. - [ ] If you run the test, give it a few weeks and judge on sales and cost per sale, not clicks. ## Not-so-frequently asked questions ### Will this lower my costs? Not by itself. Google notes that if your campaign isn’t budget-limited, priority alone changes little, and restricting channels can narrow what bidding has to work with. ### Is the AI Max test free to run? The test uses your ad budget, split 50/50 between your normal campaign and the AI Max version. ### Do I have this today? It’s rolling out over the coming months, so you may not see it yet. ### What is AI Max? Google’s set of AI options for Search campaigns, such as broader matching of search terms and automatic asset changes. Test it, don’t assume it. ## Things your agency won’t say - “Let the AI handle it” still means Google picks where your money goes. - Blocking a channel with 0% is a decision, not a fix. Check it doesn’t starve your bidding. - A test only helps if you wrote down your starting numbers first. ## Jargon Jail **Locked up: “Search Partners”** Other websites that show Google search ads outside Google itself. **You pay for clicks there too, and quality varies.** ## Where to go next - Start here: [Google Ads for beginners](/blog/google-ads-for-beginners) - The basics: [What are paid ads?](/blog/what-are-paid-ads) - Know your numbers: [CAC and LTV explained](/blog/cac-and-ltv-explained) - Everything on ads: [PPC, dumbed down](/ppc) ## Sources 1.
