Google today added two optional budget controls to Google Ads that let advertisers rank channels as "High priority" or "Low priority" and put a daily percentage limit on what low-priority channels such as Search partners and the Google Display Network can spend. The controls cover Search, Shopping, Performance Max and Demand Gen campaigns, and a Google help page dates the start of the rollout to October 15, 2026. In February 2027 the older Display Expansion budget behavior on Search campaigns goes away.

In Short

Google Ads now lets advertisers tell it which places to spend money first, such as Google Search, and which places come second, such as partner websites and the Display Network. Advertisers who stayed away from those secondary networks because they could not control the spend can now set a percentage of the daily budget those networks should not go past, although Google says it will only try to respect that number. If you run Search campaigns with Display turned on, the way that spend is split changes in February 2027 unless you set the new controls yourself.

What Google published

The announcement came in a post on the Google Ads & Commerce Blog dated October 14, 2026, written by Tal Akabas, Director of Product Management, Google Ads. Two Google Ads Help Center pages document the mechanics: "About channel prioritization and budget allocation" and "About shared budgets." Google also briefed journalists at a virtual Google Ads roundtable on October 13, 2026, under an embargo that lifted at 8:00 AM Pacific Time on October 14, according to invitation emails Google's communications team sent to PPC Land.

The blog post frames the change around control. "Marketers want more transparency into their ad campaigns and choice over how they direct their ad budgets," Akabas wrote. The post places the two features alongside Smart Bidding Exploration and campaign total budgets as tools that, in Google's words, "put more control into the hands of advertisers."

There are two features, and they do different jobs. Channel prioritization sorts inventory into two tiers. Budget allocation sets a percentage ceiling on a low-priority channel. The second only exists on top of the first: a channel has to be marked Low priority before an allocation can be attached to it.

How channel prioritization works

According to the help page, each channel can be assigned one of two levels, at the account, shared budget or campaign level. For High priority channels, "Google AI prioritizes spend on High priority channels (within your target if you use Target CPA or Target ROAS) before distributing any remaining budget to Low priority channels." Low priority channels receive spend after the High priority tier has been funded. By default, according to the help page, all channels are set to High priority, which means nothing changes in an account until someone moves a channel down.

The channels that can be ranked depend on the campaign type. The help page lists them as follows:

  • Search campaigns: Google Search, search partners, Google Display Network
  • Shopping campaigns: Google Search, Google search partners
  • Performance Max campaigns: Google channels, Google search partners, Google Display Network
  • Demand Gen campaigns: Google channels, Google Display Network

The grouping in the last two rows matters. In Performance Max and Demand Gen, "Google surfaces like Search, YouTube, Maps, Gmail, and Discover are prioritized together as 'Google channels,'" according to both the blog post and the help page. A Performance Max advertiser therefore cannot put YouTube in a lower tier than Search. Only the two networks outside Google's own properties can be ranked separately. The help page points advertisers who want finer control over individual Google surfaces toward Search and Demand Gen campaigns, "which each allow opt outs of all supported channels individually."

Search partners is Google's syndication network of non-Google search sites and apps, included by default in Search campaigns. The Display Network is Google's inventory on third-party websites and apps.

Where prioritization does nothing

The most important limitation sits in the bid strategy table on the help page. Prioritization only redistributes money when a campaign runs out of budget before it runs out of opportunities. When a campaign using Target CPA or Target ROAS is not limited by budget, "Google AI aims to hit your target across all channels, so priority levels generally don't change how spend is distributed," according to the help page. The blog post makes the same point, stating that "channel prioritization alone will generally not have an impact there."

The help page then describes the behavior strategy by strategy:

  • Target CPA, Target ROAS and Target CPC, not limited by budget: prioritization does not change how the budget is spent, but budget allocations on Low priority channels still apply.
  • Target CPA, Target ROAS and Target CPC, limited by budget: High priority channels spend first within the target. If more spend on High priority channels would exceed the target, budget shifts to Low priority channels "when they can deliver conversions at your target."
  • Maximize Conversions, Maximize Conversion Value, Maximize Clicks, Manual CPC and Target Impression Share: High priority channels spend the budget first, and whatever cannot be spent there, "based on your campaign settings or eligible traffic," goes to Low priority channels.

The table lists Target CPC among the target-based strategies. The blog post mentions only Target CPA and Target ROAS.

How budget allocation works

For a channel set to Low priority, an advertiser can enter a percentage. "When a channel or channel grouping is set as 'Low priority,' advertisers will be able to specify a maximum percentage of their daily budget to stay within their desired boundaries on those channels," Akabas wrote. "On a best-effort basis, our tools will aim to keep spend on those channels within that limit."

The help page is more precise about the base of that percentage. Budget allocation "is calculated as a percentage of the campaign's average daily budget," not as a percentage of actual campaign spend. Its worked example: a 5% allocation on a $1,000 average daily budget means Google will aim to keep spend on that channel at or below $50 per day.

Three further rules on the help page shape how the limit behaves in practice:

  • The allocation resets every day, and unspent or overspent amounts do not carry over.
  • Setting a Low priority channel's allocation to 0% stops spend there: "If you set a Low priority channel's budget allocation to 0%, Google won't spend on that channel."
  • The limit is not binding. Google AI "will aim to limit the spend on that channel to within the percentage of budget that you specified, but this isn't a guarantee, and daily spend on that channel may occasionally exceed your budget allocation."

The help page adds that spend on a channel may exceed its allocation "including on days when your campaign spends more than its average daily budget." That qualifier interacts with a rule PPC Land covered earlier this year. Google Ads campaigns can spend up to twice the average daily budget on a single day, within a monthly ceiling of 30.4 times the daily figure. On a $1,000 campaign that overdelivers to $2,000 on a given day, the 5% allocation still points at $50, because it is tied to the average budget rather than to what was actually spent, but Google's documentation does not promise the channel will stay there.

Why the limit matters more than the ranking

Budget allocation is the part of the release that reaches campaigns that are not budget-constrained. Google says as much. The allocation is "particularly helpful for campaigns with Target CPA or Target ROAS bidding that are not limited by budget since channel prioritization alone will generally not have an impact there," according to the blog post.

That distinction is not academic. Since August 17, 2026, budget-capped campaigns using Target CPA or Target ROAS have been steered back toward their stated targets instead of the lower cost per acquisition their budget allowed, a change that covers Search, Shopping, Performance Max and Demand Gen. Prioritization only acts on the budget-limited group. A campaign that has headroom, which is the condition many target-based campaigns run in, will see its channel mix change only if an advertiser sets a percentage.

From opt-outs to a middle setting

Google positions the controls as an alternative to switching networks off. "These features give marketers more control than all-or-nothing opt-outs," Akabas wrote. "Marketers who have historically opted out of Search partners and the Google Display Network can use this new lever to test these networks with more confidence and clearer limits, rather than turning them off entirely."

Read against Google's recent history with those networks, the pitch has a clear commercial dimension. Research by Intelligency Group in June 2025 found that Search partner placements delivered a 37% lower return on ad spend than Google Search, and Adalytics estimated in November 2023 that the network generated roughly $10.5 billion a year for Google. Google removed parked domains from the Search Partner Network on February 10, 2026, after a year of phased changes, and it has offered site-level placement reporting for the network since August 2025.

Performance Max is where the opt-out question has been sharpest. A "Partners Alfa" setting that let Performance Max advertisers switch Search partners and the Display Network on or off separately was spotted in an alpha test on April 30, 2026. By late July, Google confirmed it was a pilot with a limited group of advertisers, and buyers at three agencies said their requests for access had been refused. The new controls do not grant that opt-out. They offer Performance Max advertisers a ranking and a percentage limit on both networks, while a 0% allocation on a Low priority channel achieves a similar result on a best-effort basis.

Is a best-effort percentage the same as an off switch? Google's own documentation stops short of saying so. The help page states the 0% outcome plainly, but the same page also says the allocation "isn't a guarantee."

February 2027: Display Expansion on Search ends

The one non-optional element of the release concerns Search campaigns that currently show ads on the Display Network. "Starting in February 2027, for Search campaigns with the Google Display Network turned on, the current spend allocation setup will go away, and advertisers may see a shift in channel spending," according to the blog post. To keep the current configuration, advertisers can set the Display Network to "Low priority" with a 50% budget allocation.

The help page names the existing setting: all Search campaigns with Display Expansion enabled "will automatically migrate to channel prioritization and budget allocation." It also lists two details the blog post leaves out:

  • As part of the change, "GDN will no longer serve on Search campaigns utilizing the Target Impression Share bid strategy."
  • Any advertiser who sets channel priorities on a Search campaign before February 2027 sees the new settings apply "right away," replacing the current Display Expansion budget behavior on that campaign.

Until then, according to the help page, Search campaigns with the Display Network turned on that have not set priorities or allocations "continue to use current Display Expansion behavior." None of the three documents describes how the existing behavior divides spend between Search and Display. The only indication is the recommendation itself: a 50% Low priority allocation is offered as the equivalent of today's setup. That 50% figure would also be subject to the same best-effort caveat that applies to every allocation.

Rollout, tools and limits

Google's documents give different rollout language. The blog post says the controls are "rolling out globally across Search, Shopping, Performance Max, and Demand Gen" and "over the next months." The help page gives a start date: "Starting on October 15, 2026, Channel Prioritization and budget allocation controls will progressively become available," adding that "feature availability in your account may vary depending on campaign type and rollout timing."

Management is limited to the Google Ads interface and Search Ads 360 at launch. "Support for the Google Ads API and Google Ads Editor is coming soon," according to the help page. Channel prioritization cannot be set from a manager account. It has to be set in each client account or at campaign level, which matters for agencies running large account portfolios through a manager login.

The account-level setting sits on a "Channel Prioritization" card under Account settings, with a separate configuration for each campaign type. A campaign can override the account default through its own settings card, and it can switch back at any time. If an account default allocation is set, it applies to every eligible campaign of that type, and the help page warns that "if a campaign currently spends more than that percentage on a Low priority channel, you may see a shift in spend on that channel after the setting is applied."

The help page lists several compatibility limits:

  • Campaign total budgets: supported with channel prioritization for Demand Gen only. Other campaign types using a total budget will not apply the settings.
  • Shared budgets: linked campaigns must all be the same type, such as all Search or all Shopping. The allocation then applies to the shared budget as a single pool across all campaigns that use it.
  • Experiments: custom experiments support the controls, but multi-campaign shared budgets are not supported, and all channels in those experiments are treated on the same priority tier.

Campaign total budgets reached Search, Performance Max and Shopping in open beta in January 2026, with flight lengths of 3 to 90 days. Advertisers who moved holiday campaigns to total budgets on those three campaign types will not be able to combine that with the new channel tiers, according to the help page.

Where the three documents differ

The blog post, the two help pages and the email Google's communications team sent to PPC Land are not fully consistent. The differences are:

Demand Gen timing and scope. The blog post lists Demand Gen among the campaign types where the controls are rolling out. The communications team's email, sent after the post went live, describes the rollout as covering "Search, Shopping, Performance Max, and soon Demand Gen." The help page lists Demand Gen among the campaign types available from October 15 but states that "Budget allocation is not supported for Demand Gen campaigns." The blog post's description of budget allocation does not mention that exclusion.

What the percentage is based on. The blog post describes a "maximum percentage of their daily budget." The help page specifies the campaign's average daily budget, not actual spend.

Shared budgets and campaign types. The blog post says the controls "also apply to shared budgets" and that distinct priority tiers can be set across Search, Shopping, Performance Max and Demand Gen. The "About shared budgets" help page says shared budgets "are only available on Search, Shopping, Display, and Video campaigns" and lists Performance Max among the campaigns that are not compatible. Read together, shared budget prioritization is in practice limited to Search and Shopping, which matches the examples the channel prioritization page gives.

How firmly prioritization stays out of the way. The blog post says prioritization will "generally not" affect campaigns that are not limited by budget, and one section of the help page says priority levels "generally don't change how spend is distributed." A later section of the same help page says that "Channel prioritization has no effect when your campaign isn't limited by budget."

Display Expansion naming and the Target Impression Share exclusion. The blog post refers to Search campaigns "with the Google Display Network turned on." The help page calls the feature Display Expansion and adds that the Display Network will stop serving on Search campaigns using Target Impression Share, which the blog post does not mention.

Bid strategies. The blog post refers only to Target CPA and Target ROAS. The help page table also lists Target CPC.

The shared budget numbers

The "About shared budgets" page defines a shared budget as "a single average daily budget that's shared by multiple campaigns in an account" and describes it as a way to let "underutilized budgets to automatically reallocate to budget-capped campaigns." Its example: $100 a day split evenly across two campaigns, with one spending only $40, leaves $10 that Google Ads can move to the second campaign.

The page also carries a performance figure. "We found on average, customers that adopt Shared Budgets and Portfolio Bid Strategies on Search campaigns typically experience +13% more conversions," according to Google, citing internal global data from January 2024 to March 2025. The number is Google's own and is not independently verified. It also measures the combination of shared budgets with portfolio bidding, not the new channel controls, and the page does not explain whether the comparison controls for increases in spend.

What the shared budget page adds to this release is a mechanical point. When prioritization and allocation are applied to a shared budget, the budget becomes one pool. A 20% Display allocation on a shared budget would be measured against the shared budget's average daily amount across every linked campaign, not against any one campaign's share of it.

Why the release matters for advertisers

For the past year, much of PPC Land's Google Ads coverage has tracked the opposite direction: defaults that widened reach or raised spend, with controls arriving later or only through tests. A debate in October over whether budget has become a performance lever followed the August 17 bidding change, and an October analysis argued that Google's revenue goals and advertisers' goals have diverged through 2026.

Channel prioritization and budget allocation sit on both sides of that argument. On one side, they give advertisers a written limit on two networks that many specialists have treated with suspicion, and they extend that limit to Performance Max, where an opt-out is still rationed. On the other side, every element of the new limit is soft. The percentage is a target, not a ceiling. Prioritization has no effect on campaigns that are not budget-limited. Performance Max advertisers can rank only three buckets. And the blog post is explicit that one purpose is to bring back advertisers who left: those who opted out of Search partners and the Display Network "can use this new lever to test these networks with more confidence and clearer limits, rather than turning them off entirely."

The timing is also stated plainly. "With these new controls in place, marketers can confidently spend as the holidays approach and meet demand during the peak season," Akabas wrote. Most accounts will meet the controls in stages over the coming months, without API or Editor support at first, and without the ability to configure them from a manager account. The February 2027 migration is the only change that reaches advertisers who do nothing, and the documentation does not yet say how much the spend mix on affected Search campaigns will move.

Timeline

Summary

Who: Google Ads, through a blog post by Tal Akabas, Director of Product Management, and two Help Center pages. The change affects advertisers running Search, Shopping, Performance Max and Demand Gen campaigns, and in particular those using or avoiding Search partners and the Google Display Network.

What: Two optional controls. Channel prioritization ranks channels as High or Low priority so that High priority channels are funded first when a campaign is budget-limited. Budget allocation sets a best-effort daily percentage limit, based on the average daily budget, on Low priority channels; it is not available for Demand Gen. Display Expansion on Search campaigns migrates to the new system in February 2027, and the Display Network stops serving on Search campaigns using Target Impression Share.

When: Announced today, October 14, 2026, after a press roundtable on October 13. The help page says availability starts progressively on October 15, 2026. The Display Expansion migration takes effect in February 2027.

Where: Globally, in the Google Ads interface and Search Ads 360. Google Ads API and Google Ads Editor support is listed as coming soon, and the settings cannot be applied from manager accounts.

Why: Google says marketers want more transparency and choice over where budgets flow, and it presents the controls as an alternative to switching networks off entirely, with the stated aim of letting advertisers who left Search partners and the Display Network test them again ahead of the holiday season.
