Google Ads adds new controls to prioritize channels and cap spending on lower-priority inventory

Google is giving advertisers new ways to steer their ad budgets inside Google Ads, adding controls that label parts of an ad network as “high priority” or “low priority” and allow marketers to cap how much money flows to lower-priority inventory. The changes are designed to replace what the company calls all-or-nothing choices with a more flexible approach that can support testing, budget protection, and steadier performance during periods of heavy demand.

The update, announced in a Google Ads product post, introduces two optional features: channel prioritization and budget allocation. Channel prioritization is meant to determine which channels get funded first. When configured, campaigns are expected to fully fund high-priority channels, within the constraints of the campaign’s targets, before moving remaining budget to lower-priority channels.

Google says the campaign types and where the controls apply will expand across the ad ecosystem. The company describes the rollout as covering Search, Shopping, Performance Max, and Demand Gen. It also says the controls will appear at both the account and campaign levels, including within shared budgets, and that distinct priority tiers can be set across those campaign types.

To make the settings practical, Google is allowing marketers to sort specific inventory into priority levels. For Search campaigns, it describes separate priority choices for Google Search, Search partners, and the Google Display Network. For Performance Max and Demand Gen, Google groups several surfaces under what it calls “Google channels,” and those groups are prioritized together. Google lists examples of those surfaces including Search, YouTube, Maps, Gmail, and Discover.

The second feature, budget allocation, targets a different problem: limiting how much of a daily budget is spent on lower-priority channels. When a channel or channel grouping is set to low priority, advertisers can specify a maximum percentage of their daily budget that should go to that inventory. Google says its system will work on a best-effort basis to keep spending on those channels within the specified limit.

Google frames the change as especially useful for advertisers running strategies that use Target CPA or Target ROAS, which are automated bidding approaches that aim to hit cost or return goals. In those cases, channel prioritization alone is described as generally not having an impact when budget is not tightly constrained. Budget allocation is positioned as a way to add guardrails so that low-priority channels are tested without allowing them to absorb a disproportionate share of spend.

The company also highlights the behavioral shift it hopes advertisers adopt. Instead of fully opting out of Search partners or the Google Display Network, marketers can keep the inventory enabled while assigning it low-priority status and then apply a budget cap. Google says this gives advertisers a “lever” to test those networks with clearer limits rather than turning them off entirely. It also notes that advertisers with campaigns already running on Search partners or the Google Display Network can optionally set a budget allocation.

One specific configuration change is already spelled out for the Google Display Network in Search campaigns. Starting in February 2027, Google says the current spend allocation setup will be removed for Search campaigns with the Google Display Network turned on. To maintain the existing configuration, advertisers are instructed to set the Google Display Network to “Low priority” with a 50% budget allocation.

Beyond the mechanics, Google’s post places the update in a broader context of giving advertisers more control while still relying on AI-driven systems to manage performance. The company points to prior additions such as Smart Bidding Exploration and campaign total budgets, describing them as steps that put more direction in the hands of marketers. In this update, channel prioritization and budget allocation are presented as optional controls that can coexist with those automated approaches, with Google saying the rollout is occurring over the next months.
