For years, Google Ads gave you two choices for Search partners and the Display Network.

On or off.

Leave them on, and some of your budget flows to inventory you may not trust. Turn them off, and you lose any incremental leads they might have delivered.

Channel prioritization adds a middle option.

You can now tell Google where your money should go first, and how much is allowed to go anywhere else.

If you have ever wondered how much of your Google Ads budget is leaving Google Search, this is the setting to look at this month.

What Did Google Announce?

On October 14, 2026, Google introduced two optional controls, channel prioritization and budget allocation, to help advertisers decide where their budgets go (Google Ads & Commerce Blog). Google says the controls are rolling out globally over the coming months across Search, Shopping, Performance Max, and Demand Gen campaigns.

The core ideas are simple:

• Channel prioritization: You label channels or channel groupings as High priority or Low priority. Google says campaigns will fully fund High priority channels (within your target when you use Target CPA or Target ROAS) before remaining budget goes to Low priority channels.
• Budget allocation: For Low priority channels, you can set a maximum percentage of your daily budget. In Google’s words, “On a best-effort basis, our tools will aim to keep spend on those channels within that limit.”
• Where it applies: Settings can be applied at the account level, the campaign level, and to shared budgets.

Google’s Ads Liaison, Ginny Marvin, framed it clearly: “these are budgeting controls and not bidding controls,” and existing opt-in and opt-out settings for the Display Network and Search partners remain in place (Relevant Audience).

How Does Google Ads Channel Prioritization Work?

The details differ by campaign type, and those differences matter when you plan your settings.

1. Search Campaigns

In Search campaigns, Google Search, Search partners, and the Google Display Network can each be given their own priority level. This is where most lead generation advertisers will feel the change, because it finally separates Google’s own results page from partner and display inventory inside the same campaign.

2. Performance Max and Demand Gen

In Performance Max and Demand Gen, Google groups its own surfaces, such as Search, YouTube, Maps, Gmail, and Discover, together as “Google channels.” You cannot rank those individually. What you can control is how budget flows to the lower-priority partner inventory. Industry coverage of Google’s help documentation notes that budget allocation is not supported for Demand Gen at launch, while channel prioritization is (PPC Land).

3. The Default Setting

Coverage of the help documentation reports that all channels start as High priority, so nothing changes in your account until you choose to adjust it (PPC Land).

4. Account, Campaign, and Shared Budget Levels

Account-level settings act as defaults for eligible campaigns. Campaign-level or shared-budget settings override them. For shared budgets, the limit applies to the whole budget across every campaign using it (Search Engine Roundtable). Reports also indicate the settings cannot be configured from a manager account, so agencies need to set them inside each client account.

How Budget Allocation Limits Low Priority Spend

Prioritization decides the order in which channels are funded. Budget allocation decides how much a Low priority channel is allowed to take. You need to understand both, because prioritization on its own often does very little.

1. It Is a Percentage of Average Daily Budget

The allocation is based on the campaign’s average daily budget, not actual spend. Google’s example, as reported by Search Engine Roundtable: 5% of a $1,000 average daily budget is $50 per day.

2. It Is Best-Effort, Not a Hard Cap

Google’s help page states that “this isn’t a guarantee, and daily spend on that channel may occasionally exceed your budget allocation.” Allocations reset daily, and unspent or overspent amounts do not carry over.

3. 0% Means Stop

Setting a Low priority channel to 0% stops spend on that channel. Marvin also confirmed that Performance Max advertisers can set a budget allocation for the Search Partner Network to 0% if they want (Relevant Audience). For many lead generation accounts, that is the headline.

4. Prioritization Alone Rarely Changes Uncapped Campaigns

Google notes that prioritization generally will not affect campaigns that are not limited by budget. If your Target CPA campaign is not budget-constrained, setting Display to Low priority without an allocation percentage may change nothing. Pair the two settings when control is the goal.

Here is how the new controls compare with the options you already had:

Why the February 2027 Display Change Matters

This is the part most advertisers will miss.

Google says that starting in February 2027, the current spend allocation setup for Search campaigns with the Google Display Network turned on will be removed, and advertisers may see channel spend shift. To keep their current setup, Google recommends setting the Display Network to Low priority with a 50% budget allocation (Google Ads & Commerce Blog).

If you have Search campaigns with Display turned on, put this on your calendar now. Decide whether you want Display in those campaigns at all, and if you do, set an intentional allocation instead of letting a default decide for you.

How to Set Up Channel Prioritization in Google Ads

According to Search Engine Roundtable’s walkthrough of the help documentation, setup starts in Account settings. Because the rollout is gradual, you may not see the option in every account yet.

1. Pull Channel-Level Results First

Before changing anything, segment your recent performance by network or channel. Look at conversions, cost per conversion, and, most importantly, how many of those conversions turned into qualified leads or sales. Our Google Ads audit guide covers how to check conversion tracking and lead quality first, since bad tracking will make every channel look better or worse than it is.

2. Open the Channel Prioritization Setting

Go to Account settings and find the Channel Prioritization card, then select the campaign type you want to configure.

3. Assign High or Low Priority

For most lead generation advertisers, Google Search stays High priority. Search partners and Display are the channels to evaluate.

4. Set a Budget Allocation for Low Priority Channels

Choose a percentage of daily budget, or 0% to stop spend. Remember it is best-effort and resets daily.

5. Override at the Campaign Level Where Needed

Brand campaigns, high-value service campaigns, and remarketing may each need different settings than the account default.

6. Test Before You Roll Out

Marvin described the settings as “fully testable using campaign Drafts & Experiments.” Where you have enough volume, test a change in one campaign before applying it account-wide, and record the date of every change.

How to Decide Each Channel’s Priority: The Channel Efficiency Index

The new controls are only as good as the decisions behind them. We use a simple framework, the Channel Efficiency Index, to decide whether a channel should stay High priority, move to Low priority with a capped allocation, or be set to 0%.

Use qualified leads, not raw conversions. A form fill from a spam bot and a booked estimate both count as a conversion in many accounts. Only one of them pays the bills. Then apply a simple rule of thumb:

• Index of 1.25 or lower: the channel is competitive with Google Search. Keep it High priority.
• Index between 1.25 and 2.0: the channel produces leads at a premium. Set it to Low priority with a modest allocation and keep testing.
• Index above 2.0, or no qualified leads after meaningful spend: set the allocation to 0% or opt out where the campaign type allows it.

Adjust the thresholds to your margins. A high-ticket service business can tolerate a higher cost per lead than a low-margin one.

Worked example (hypothetical numbers): a home services company spends on a Search campaign with partners and Display turned on. Over the last 90 days, Google Search produced qualified leads at $80 each. Search partners came in at $96 per qualified lead, an index of 96 ÷ 80 = 1.2, so partners stay High priority. Display came in at $200 per qualified lead, an index of 200 ÷ 80 = 2.5, so Display moves to Low priority at 0% in that campaign. In the company’s Performance Max campaign, partner inventory produced conversions but almost none were qualified, so Search partners are set to Low priority at 0% there too.

The scorecard makes the trade-offs visible. Search partners are not automatically bad, and Display is not automatically wasteful. The point is to make each decision from qualified lead data instead of assumptions, and to revisit it as results change.

Common Channel Prioritization Mistakes to Avoid

Setting Low Priority Without an Allocation

If the campaign is not limited by budget, Low priority alone may not change spend. Add an allocation percentage when you want real control.

Judging Channels on Raw Conversions

Partner and display traffic can generate cheap form fills that never turn into customers. Judge every channel on qualified leads or revenue, and make sure your CRM or call tracking feeds that data back.

Treating the Cap as Guaranteed

Google describes the allocation as best-effort. Check channel spend in your reports after the change rather than assuming the cap held every day.

Ignoring the February 2027 Deadline

If your Search campaigns include Display, decide on a setting before the current allocation setup is removed, so spend does not shift in a way you did not choose.

Changing Everything at Once

Smart Bidding needs time to adjust. Change one campaign or one channel at a time, note the dates, and compare results over several weeks.

What This Means for Lead Generation Advertisers

For businesses that buy clicks to generate calls and form fills, this update is mostly good news.

1. More Spend Where Intent Is Highest

People searching on Google for a service right now usually show strong commercial intent. Prioritizing Google Search keeps more of your budget pointed at those searches.

2. Safer Testing of Partner Inventory

Instead of turning Search partners or Display fully on, you can test them with a small, defined share of budget and keep them only if qualified leads follow.

3. A Better Fit With the Rest of Your Search Strategy

Paid search works best alongside organic visibility. If you are weighing where to invest, our comparison of SEO vs PPC and our look at why Google Ads is not going away in the age of AI Mode are good next reads.

4. Leads Still Have to Be Worked

Better channel control means more of the right leads. Those leads still need a fast response. Our guide to speed to lead explains why follow-up time often matters as much as cost per lead.

If you work with an outside team, this is also a good test of how they manage your account. Our guide on choosing the right PPC management agency covers what to ask.

Google Ads Channel Prioritization FAQs

What is Google Ads channel prioritization?

It is a setting that lets you label channels such as Google Search, Search partners, and the Display Network as High or Low priority. High priority channels are funded first, and remaining budget goes to Low priority channels.

What is budget allocation in Google Ads?

Budget allocation lets you set a maximum percentage of a campaign’s average daily budget for Low priority channels. Google aims to stay within that limit on a best-effort basis.

Which campaign types support channel prioritization?

Google lists Search, Shopping, Performance Max, and Demand Gen. Coverage of Google’s help documentation notes that budget allocation is not supported for Demand Gen at launch.

Can I stop Search partner spend in Performance Max?

Yes. Google’s Ads Liaison confirmed that Performance Max advertisers can set a budget allocation for the Search Partner Network to 0%, after marking it Low priority.

Is the budget allocation a hard cap?

No. Google states it is not a guarantee and daily spend may occasionally exceed the allocation. Allocations reset each day, and unspent or overspent amounts do not carry over.

Does setting a channel to Low priority reduce its spend?

Not always. Google says prioritization alone generally will not affect campaigns that are not limited by budget. Add a budget allocation percentage when you want to limit spend.

What changes in February 2027?

Google says the current spend allocation setup for Search campaigns with the Display Network turned on will be removed. To keep the current behavior, Google recommends setting Display to Low priority with a 50% allocation.

Do my existing network opt-outs still work?

Yes. Google’s Ads Liaison said the existing opt-in and opt-out settings for the Display Network and Search partners are unchanged.

Why don’t I see the setting in my account?

Google is rolling the controls out gradually over the coming months, so availability may vary by account and campaign type.

Control Where Your Budget Goes First

Most wasted ad spend is not dramatic. It leaks quietly into placements nobody chose on purpose.

Channel prioritization gives you a way to stop the leak without giving up on testing.

Priority decides which channel gets paid first.

Allocation decides how much everything else is allowed to spend.

A smart setup follows a clear order: measure each channel on qualified leads, keep Google Search as High priority, move weaker channels to Low priority with a deliberate allocation, set channels that do not produce qualified leads to 0%, test changes one campaign at a time, and settle your Display settings before February 2027.

Get that right, and more of every dollar you put into Google Ads goes toward the searches most likely to become customers.
