Google Ads Channel Prioritization: How High/Low Priority and Budget Allocation Work

Google Ads channel prioritization lets you rank the channels a campaign can spend on as High or Low priority, and cap Low-priority channels at a percentage of the daily budget. Google announced the controls on 14 October 2026 for Search, Shopping, Performance Max and Demand Gen. They roll out gradually from 15 October, and the caps are best-effort, not guarantees.

What is Google Ads channel prioritization?

Until now, most channel decisions in Google Ads were on or off. You could include Search partners or the Google Display Network in a Search campaign, or exclude them. Google’s announcement, written by Tal Akabas, Director of Product Management for Google Ads, opens with “Say goodbye to all-or-nothing channel targeting.”

Google added two optional controls that work together:

• Channel prioritization: you mark each channel, or group of channels, as High priority or Low priority. Google’s Help Center says High-priority channels receive spend first and Low-priority channels receive spend after them.
• Budget allocation: for a Low-priority channel, you can enter a percentage of the campaign’s average daily budget. Google’s systems then aim to keep spend on that channel at or below that amount.

Google says the point is to let advertisers test networks such as Search partners or the Display Network “with more confidence” instead of switching them off completely. According to the Help Center, advertisers who previously opted out of these networks can use the controls to “opt back in with more confidence”.

Which campaigns and channels can you prioritize?

The controls do not work the same way in every campaign type. This is what Google’s Help Center lists as of 20 October 2026:

In Performance Max and Demand Gen, Google groups its own surfaces (Search, YouTube, Maps, Gmail and Discover) as “Google channels”, so you cannot rank YouTube separately from Search there. Google points advertisers who want that level of control to Search and Demand Gen campaigns, which allow individual opt-outs.

Demand Gen is the least settled part. Google’s blog post lists it among the campaign types, while the Help Center says budget allocation is not supported for Demand Gen. Search Engine Journal, which attended Google’s briefing, reported that limited Demand Gen testing starts in November. PPC Land noted the same inconsistency between Google’s documents.

How does budget allocation work in Google Ads?

Budget allocation is the part most advertisers will actually feel. The Help Center sets out these rules:

1. It only applies to Low-priority channels. You first move a channel to Low priority, then optionally enter a percentage.
2. The base is the average daily budget, not actual spend. Google’s example: a 5% allocation on a $1,000 average daily budget means Google aims to keep that channel at or below $50 per day.
3. It resets every day. Unspent or overspent amounts do not carry over to the next day.
4. It is best-effort. Google’s announcement puts it this way: “On a best-effort basis, our tools will aim to keep spend on those channels within that limit.” The Help Center adds that spend can occasionally go above the allocation.
5. 0% means no spend. The Help Center says that if you set a Low-priority channel’s allocation to 0%, Google won’t spend on that channel.

For shared budgets, the allocation applies to the shared budget as a whole, and all linked campaigns must be the same campaign type.

Does channel prioritization change spend for Target CPA and Target ROAS?

Often it does not, and this is easy to miss. Google’s Help Center explains that the effect depends on your bid strategy and on whether the campaign is limited by budget:

In our view, this makes the percentage cap the more practical lever for most target-based campaigns, and the priority label more useful for budget-limited campaigns. Search Engine Journal’s Brooke Osmundson made similar points: she sees the most potential in budget allocation, and she cautions against moving channels to Low priority on campaigns already hitting their CPA or ROAS targets, since that could reduce the options Google’s bidding system has to work with.

What changes for Display Expansion in February 2027?

This is the part that can affect accounts that never touch the new settings. According to Google’s Help Center:

• Until February 2027, Search campaigns with the Display Network turned on and no channel settings keep the current Display Expansion behavior.
• From February 2027, those campaigns migrate to channel prioritization and budget allocation, which may shift spend between Google Search, Search partners and the Display Network.
• To keep the current setup, Google suggests setting the Google Display Network to Low priority with a 50% daily allocation.
• The Display Network will stop serving on Search campaigns that use Target Impression Share.
• If you save channel settings on a Search campaign before February 2027, they take effect immediately and replace the current Display Expansion behavior.

Because every channel defaults to High priority, an account that does nothing could see the Display Network treated very differently after the migration. Put a date in your calendar to review every Search campaign that has Display Expansion on.

How do you set channel priority in Google Ads?

Google’s Help Center describes two places to do it. The controls are rolling out progressively, so you may not see them in every account or campaign type yet.

1. Account level: go to Account settings, open the “Channel Prioritization” card, choose the campaign type, set each channel to High or Low priority, add an allocation percentage for Low-priority channels if you want one, then save.
2. Campaign level: open the campaign, go to Settings, expand “Channel Prioritization”, choose “Use campaign-level settings” to override the account default, set priorities and allocations, then save. You can switch back to the account default at any time.

A few limits apply. Settings can’t be configured from a manager account, so agencies have to set them in each client account. The controls are available in the Google Ads interface and Search Ads 360. The Help Center says support for the Google Ads API and Google Ads Editor is “coming soon”, although SEJ reported that Google said API support would be available at launch. For campaign total budgets, the settings are supported only for Demand Gen. Custom experiments can use the controls, but multi-campaign shared budgets aren’t supported there, and all experiment channels share the same priority tier.

Can you see results by channel?

Google’s announcement and Help Center page do not describe new reporting for these controls. Search Engine Journal reported from Google’s briefing that Performance Max already has channel-level reporting, that expanded channel reporting for Search is expected in Q1 2027, and that Google plans account-level budget allocation insights. Until then, SEJ notes, advertisers can keep using the existing network segmentation in Search reports to compare Google Search with Search partners.

SEJ also reported that Google is running a separate small alpha test of more advanced Performance Max channel controls, and that both approaches will run alongside each other for now.

Should you use channel prioritization? Our recommendations

The steps below are our own suggestions, not Google guidance. They are written for small and mid-sized advertisers in Lebanon, Saudi Arabia and the Gulf who manage their own accounts.

1. Start with campaigns that are limited by budget. That is where priority actually changes the order of spend.
2. Test, don’t flip. If you excluded Search partners in the past, try them as Low priority with a small allocation (SEJ’s example was 20%) instead of turning them fully on.
3. Judge by conversions, not clicks. Compare cost per conversion by network for at least two to four weeks before you raise any cap. Our guide to measuring campaign performance covers which metrics to track.
4. Change one thing at a time. Treat each allocation change like an A/B test, so you know what caused the result.
5. Leave well-performing target campaigns alone. If a Target CPA or Target ROAS campaign is hitting its goal and isn’t budget-limited, restricting channels may simply limit the bidding system’s options, a point SEJ’s Brooke Osmundson also makes.

Channel controls also sit alongside Google’s other AI features. If you use AI Max for Search, keep in mind that the two settings answer different questions: AI Max is about which searches you match, while channel priority is about where the budget goes.

What to do now: a quick checklist

• Check Account settings for the “Channel Prioritization” card. If it isn’t there yet, check again in a few weeks.
• List every Search campaign with the Display Network on, before February 2027.
• Note which campaigns are “Limited by budget” and which use Target CPA or Target ROAS.
• Pull a network-segmented report for the last 30 days as your baseline.
• Pick one campaign to test a Low-priority channel with a small cap, and write down the start date.
• If you manage client accounts, plan time to set controls per account, since manager accounts can’t set them.

FAQ

What is channel prioritization in Google Ads?

It is a setting that lets you mark each channel a campaign can spend on as High or Low priority. High-priority channels receive spend first, and Low-priority channels receive spend after them. Google announced it on 14 October 2026.

Which campaign types support channel prioritization?

Google lists Search, Shopping, Performance Max and Demand Gen. Google’s Help Center says budget allocation is not supported for Demand Gen, so Demand Gen campaigns get priority settings only. SEJ reported that limited Demand Gen testing is expected to begin in November.

Is the budget allocation percentage a hard cap?

No. Google says allocation works on a best-effort basis and spend may occasionally exceed it. The percentage is based on the campaign’s average daily budget and resets every day.

Can I stop spend on Search partners in Performance Max?

Google’s Help Center says that if you set a Low-priority channel’s budget allocation to 0%, Google won’t spend on that channel. Search partners can be set as a channel in Performance Max, once the controls are available in your account.

Can I prioritize YouTube separately in Performance Max?

No. In Performance Max and Demand Gen, Search, YouTube, Maps, Gmail and Discover are grouped as “Google channels”. Google suggests Search and Demand Gen campaigns for individual opt-outs.

Will channel prioritization change my Target CPA or Target ROAS campaigns?

Usually not, if the campaign isn’t limited by budget. In that case Google aims to hit the target across all channels, although allocations on Low-priority channels still apply. When the campaign is budget-limited, High-priority channels spend first within the target.

What happens to Display Expansion in February 2027?

Search campaigns with the Display Network on will move to the new system, which may shift spend between networks. To keep the current setup, Google suggests setting the Display Network to Low priority with a 50% allocation.

Can I set channel priorities from a manager account?

No. Google’s Help Center says prioritization can’t be set from a manager account, so you set it in each client account or at campaign level. The Help Center lists Google Ads API and Google Ads Editor support as coming soon.
