TLDR

Google Ads is rolling out channel prioritisation and budget allocation controls across Performance Max, Search and Shopping campaigns, with Demand Gen to follow. Advertisers set channels to High or Low priority; Google's AI funds High priority first, then directs remaining budget to Low priority channels up to a daily percentage cap. Search campaigns running Display Network spend must act before February 2027 or lose their current allocation behaviour.

KEY TAKEAWAYS

01High priority channels receive full AI-funded budget before any spend reaches Low priority channels.

02The daily spend cap for Low priority channels is best-effort only; unspent or overspent amounts do not roll over.

03Setting a channel allocation to 0% blocks all spend on that channel for the day.

04Search campaigns with Display Network enabled must set Display to Low priority at 50% before February 2027.

05Rollout is progressive across accounts, with Demand Gen channel controls arriving later than Search and Shopping.

Performance Max (PMax), Google's fully automated campaign type, has carried one persistent complaint since its 2021 rollout: advertisers fund the campaign, Google decides where the money goes, and the only way to push back was to switch an entire network off. That is now changing.

## How the two controls work

Google is rolling out two linked features across Search, Shopping and PMax campaigns, with Demand Gen to follow. The first is channel prioritisation, which lets advertisers label each ad network either High or Low priority. Google's AI fully funds High priority channels within a campaign's Target CPA or Target ROAS targets before any remaining budget flows to Low priority channels.[\[1\]](https://support.google.com/google-ads/answer/18385152?hl=en&ref=promptthemarket.com) The AI drains the front of the queue before it touches the back.

The second feature, budget allocation, sits on top of that queue. Advertisers can set an optional daily percentage cap on what Low priority channels can spend. That cap resets every day, and any unspent or overspent amounts do not carry over; setting the allocation to 0% blocks all spend on that channel for the day.[\[1\]](https://support.google.com/google-ads/answer/18385152?hl=en&ref=promptthemarket.com) It is a daily gate, not a monthly budget wall.

Tal Akabas, Director of Product Management at Google Ads, said: "Say goodbye to all-or-nothing channel targeting. You can now categorize ad networks by priority and allocate budget to secondary channels to test them safely."[\[2\]](https://blog.google/products/ads-commerce/channel-prioritization-budget-allocation/?ref=promptthemarket.com)

## The limits on those caps

The word "cap" will catch agency attention, but the fine print matters. Google describes budget allocation as a "best-effort" limit. The AI will try to stay inside the percentage, but it carries no guarantee. Accounts that need hard channel-level spend limits for compliance or strict budget management should treat this as directional control, not a guaranteed ceiling.

For Search campaigns specifically, advertisers can now prioritise Google Search, search partners and the Google Display Network separately, and can opt back into search partners or Display rather than opting out entirely.[\[2\]](https://blog.google/products/ads-commerce/channel-prioritization-budget-allocation/?ref=promptthemarket.com) Before this update, the choice was binary: the channel was on or off. The new controls let teams test Display at, say, 10% of daily budget without committing the full remaining pool to it.

An alpha of the feature was sighted in August 2026, before the official announcement on 14 October 2026.[\[3\]](https://www.seroundtable.com/google-ads-channel-prioritization-budget-allocation-42297.html?ref=promptthemarket.com) Rollout is progressive and account availability will vary over the coming months.

## What Australian teams need to do before February 2027

There is a deadline buried in the product update that Australian media buyers should not miss. From February 2027, Google will remove the current spend allocation setup for any Search campaign that has the Google Display Network turned on.[\[1\]](https://support.google.com/google-ads/answer/18385152?hl=en&ref=promptthemarket.com) Accounts that do nothing will lose their existing allocation behaviour entirely.

To preserve the current split, advertisers must log in and manually set the Google Display Network to Low priority with a 50% daily budget allocation before that date.[\[1\]](https://support.google.com/google-ads/answer/18385152?hl=en&ref=promptthemarket.com) That is an active opt-in, not a passive default.

For PMax, the new controls address the core frustration agencies have raised since 2021: the inability to steer AI-driven budget across channel types without going dark on a network entirely. The Low priority plus percentage cap combination gives a middle path: keep the network on, cap its daily draw, and watch what it produces.

The practical Monday question for search and performance teams: audit every Search campaign with Display Network enabled and set a calendar reminder for January 2027 to apply the Low priority and 50% allocation before Google enforces the change in February.
