Google Ads is adding two settings, Channel Prioritization and Budget Allocation, that decide which inventory gets funded first and how much a lower-ranked network may consume. Search Engine Journal reported the details on October 14 following a virtual roundtable with Google’s product group. The rollout is global and staged over the coming months, and it spans Demand Gen, Performance Max, Shopping, and Search campaigns.
Each channel can be tagged High priority or Low priority. Google’s system funds the high tier first, then sends whatever budget remains to the low tier, while still working toward a Target CPA or Target ROAS goal. A Search campaign, for instance, could favor Google Search and demote Search Partners or Display to the lower tier.
Options differ by campaign type. Inside Demand Gen and Performance Max, Google treats its own surfaces as a single block: Maps, Gmail, Discover, YouTube, and Search. Advertisers cannot rank those individually. Every channel starts at High priority, so any downgrade is a manual choice.
Budget Allocation is the more consequential half. For a Low priority channel, an advertiser can set a percentage limit on daily budget. Google’s help documentation gives the arithmetic: with a daily budget averaging $1,000, a 5 percent setting tells the system to keep that channel near $50 daily or less. The figure is a share of the average daily budget, not of actual spend. The count restarts every day, and leftovers or overruns are not carried forward.
The limit is not a hard cap. Google describes it as best effort, and its documentation says daily spend on a channel may occasionally exceed the stated share. Setting a channel to 0 percent is allowed and stops spend there, including inside Performance Max.
The caps also matter for campaigns that are not budget constrained. Google explained that prioritization by itself does little for tCPA and tROAS campaigns that have spare budget, so the percentage limit is the lever that still steers spend across networks. Advertisers who opted out of Search Partners or Display over traffic quality worries can use the limits to return with a defined ceiling.
Setup happens in account settings, and each supported campaign type can carry its own defaults. Individual campaigns override those defaults, and the controls work with shared budgets, where the allocation covers the pooled budget across every campaign using it. Google confirmed API support at launch. Campaign experiments came up in the roundtable, but Google gave no date. Limited testing for Demand Gen is slated for November.
One change carries a deadline. Today, a Search campaign with both networks switched on gives Search inventory precedence over Display, and Search Partners gets no such treatment. Google will end that Display allocation setup in February 2027. Because every channel defaults to High priority, accounts that change nothing could see spend move between networks. To preserve current behavior, Google recommends dropping Display into the low tier and giving it half the budget share, and said a one-click migration will be offered when the controls launch.
The controls raise an obvious tension with automated bidding. Roundtable attendees asked why anyone should rank channels by hand if automated bidding against CPA or ROAS targets already chases results. Google’s team conceded that automation has eased much of campaign management and said the goal is more spending control without removing optimization toward goals. None of the material offers independent measurement of how tiers or caps affect results.
Reporting is thin for now. Performance Max already reports by channel, and Google expects wider channel reporting for Search in the first quarter of 2027. Current network segmentation stays available until then, and Google plans account-level insights on budget allocation. Separately, a small alpha test of deeper channel controls for Performance Max will run alongside the new settings.
For paid search teams, the practical read is that the caps are a testing tool. A 20 percent limit on Search Partners is a target to monitor daily, not a guarantee, so pacing reports matter more than the setting itself. Campaigns already hitting their CPA or ROAS goals have little reason to demote channels, since fewer eligible placements gives bidding less to work with.
Before February, audit every Search campaign with Display enabled and decide whether to follow Google’s low-tier, half-share recommendation or accept the new default and its spend shift. Teams that skipped Search Partners should pick one campaign with a small cap to test it.
