Google Ads channel prioritization: control what you spend on Search Partners and Display

For years, a slice of your Google Ads budget went to Search Partners and the Display Network whether you wanted it there or not. In October 2026 Google gave you a dial for it.

The short version

On October 14, 2026, Google announced two new controls: channel prioritization and budget allocation.¹ You can now mark each channel in a campaign as High or Low priority, and put a daily percentage cap on the Low ones. Google funds the High channels first and sends only what’s left to the Low ones. The rollout began on October 15 and will reach accounts gradually over the coming months.²³

The practical meaning for a small business: if your Search Partners or Display clicks have been cheap but useless, you can now turn them down without switching them off completely. And if you do nothing, nothing changes yet, because every channel starts on High.

Why this matters

When you run a Search campaign, Google can also show your ads on Search partners (other sites that use Google’s search, such as some retailer and directory sites) and, if it’s switched on, the Display Network (banner placements across millions of websites and apps). Until now, the choice was all or nothing. You either included those networks or you didn’t, and you had little say in how much of the daily budget they took.

For a lot of local service businesses, that mattered. The clicks on partner sites and display placements often cost less, which looks good in a report, but in the local service accounts we manage they convert far less often than a person typing “furnace repair Burnaby” into Google. A cap lets you keep a small, controlled test running instead of choosing between “all in” and “off.”

What each campaign type lets you control

The controls aren’t the same everywhere. Here’s what Google’s help page lists:²

One limit to know before you get excited about Performance Max: YouTube, Gmail, Discover, Maps and Search are grouped together as “Google channels.” You can’t prioritize or cap them one by one. Only Search partners and the Display Network can be set separately.² To see how much each of those channels is actually doing, use the channel performance report that Google added to Performance Max in 2025.⁶

How the High, Low and percentage settings work

• High priority channels are funded first, within your target CPA or ROAS goals.²
• Low priority channels only get what’s left after the High channels are funded.
• Budget allocation is an optional cap on a Low channel, set as a percentage of the campaign’s average daily budget. A 5% cap on a $1,000-a-day campaign means Google aims to spend no more than $50 a day on that channel.⁵
• A 0% allocation stops spend on that channel entirely.²

Two caveats are worth reading twice. First, the cap is best-effort, not a hard limit. Google’s help page says spend on those channels may occasionally go over the allocation.² PPC Land put it well: a cap that aims rather than binds is a different instrument.⁵ Second, if your campaign uses Target CPA or Target ROAS and isn’t limited by budget, Google says changing priority alone will generally have little effect.² These are budget controls, not bidding controls.

What happens if you do nothing

All channels default to High priority, so your campaigns keep behaving the way they do today.² There’s one date to put in your calendar, though. In February 2027, Google is retiring the old Display Expansion setup for Search campaigns that have the Display Network switched on, and those campaigns will move to the new controls automatically. Google’s suggestion for keeping today’s behaviour is to set the Display Network to Low priority with a 50% budget allocation.²³

Most small accounts we see don’t need Display inside a Search campaign at all. February is a good deadline to decide on purpose.

How to use it in a small business account

1. Look at the numbers by network first. In a Search campaign, segment your results by network to compare Google Search with Search partners. In Performance Max, open the channel performance report.⁶ You’re looking at cost per conversion, not cost per click, and you need real conversions tracked. If you count calls, make sure call tracking is set up.
2. Move the weak channels to Low, don’t delete them. If Search partners or Display convert at a much higher cost than Google Search, set them to Low priority.
3. Start with a small cap and give it time. PPC specialist Tudor Daniel suggests starting Search partners around 10 to 15% and Display around 10%, then judging cost per conversion after a few weeks.⁷ Treat that as a starting point, not a rule. If a channel still doesn’t produce leads at a price you can live with, move it to 0%.
4. Re-check after the busy season. Holiday traffic changes partner and display performance. Look again in January before you make the settings permanent.

A few examples of how this plays out:

• HVAC and trades: emergency searches happen on Google Search. Keep Search on High, start Search partners on Low with a small cap, and keep Display out of Search campaigns unless you’re running a deliberate awareness test.
• Realtors: buyers browse for months. A capped Display allocation inside Performance Max can keep you in front of past site visitors without letting it eat the lead budget.
• Salons and clinics: bookings come from people searching nearby. Protect Search and Maps first; partner traffic rarely books a chair.

Where to find the settings

There are two levels. At the account level, go to Account settings, open the Channel Prioritization card, pick a campaign type and set each channel to High or Low. This becomes the default for every campaign of that type. To override it for one campaign, open the campaign’s Settings, expand Channel Prioritization and choose to use campaign-level settings.²

The controls are available in the Google Ads interface and Search Ads 360, but not from manager accounts. Google Ads Editor support is listed as coming soon.²⁴ Because the rollout is gradual, the card may not appear in your account yet.

What we’d watch

Coverage of the launch has pointed out gaps between what Google’s product team has said and what the help page states, for example on whether Demand Gen campaigns can use a percentage cap.⁵ Go by the help page and by what your own account shows, and check again as the rollout finishes.

The bigger picture is a welcome one. Google has spent several years taking manual controls away in favour of automation. This one hands a little control back, and for small budgets, where every wasted dollar shows, that’s worth using. If you’re still deciding between campaign types, our comparison of Performance Max vs Search covers the trade-offs, and negative keywords remain the other half of keeping spend clean. October also brought automated promotions, which are on by default and worth checking while you’re in the settings. For budgeting, see how much Google Ads cost.

Frequently Asked Questions

What is channel prioritization in Google Ads?

It is a setting Google announced on October 14, 2026 that lets you mark each channel in a campaign, such as Google Search, Search partners or the Display Network, as High or Low priority. Google funds High priority channels first and sends only the remaining budget to Low priority ones.

Can I limit how much Google Ads spends on Search partners?

Yes. Set Search partners to Low priority and add a budget allocation, which caps that channel at a percentage of the campaign's average daily budget. Google treats the cap as best-effort, so spend can occasionally go slightly over. A 0% allocation stops spend on the channel.

Does channel prioritization work in Performance Max?

Partly. In Performance Max you can prioritize and cap Search partners and the Display Network. YouTube, Gmail, Discover, Maps and Search are grouped together as Google channels and can't be set one by one.

What happens if I don't change anything?

Nothing changes for now, because every channel starts on High priority. In February 2027, Search campaigns that use Display Expansion move to the new controls automatically, so review your Display setting before then.

Should a small business turn off the Display Network in Search campaigns?

In most local service accounts we would. In the accounts we manage, Display clicks are cheaper but rarely turn into calls or bookings. Check your own cost per conversion by network first, then set Display to Low with a small cap or to 0%.

When will I see channel prioritization in my account?

Google started rolling it out on October 15, 2026 and says it will reach accounts gradually over the coming months. It is available in the Google Ads interface and Search Ads 360, but not from manager accounts.
