Google Ads Channel Prioritization and Budget Allocation Guide

Google Ads channel prioritization is a new setting that decides which surface your campaign budget goes to first, and budget allocation sets the maximum share of your daily budget a lower-priority surface can use. On October 14, 2026, Google said on its official blog that it is rolling the feature out in phases to Search, Shopping, Performance Max and Demand Gen campaigns. In February 2027, the existing spend behavior of Search campaigns with display expansion will change, so check those campaigns ahead of time if you run them.

Google Ads channel prioritization and budget allocation: what changed

According to Google's announcement, channel prioritization sorts a channel or channel group into High priority or Low priority. Budget is first given in full to the channels set to high, and the remaining budget goes to the channels set to low. In campaigns that use a target CPA or target ROAS bidding strategy, this works within that target range.

Budget allocation is an optional setting that applies only to channels set to low. It sets the maximum share of the daily budget that channel can use, and a 0% setting means no spend on that channel. The Google Help article explains that this share is best-effort rather than a guaranteed limit, so it can exceed the daily cap, and unused budget is not carried over to the next day.

Channels you can choose and supported scope by campaign type

Campaign type	Channels you can prioritize	Budget allocation
Search	Google Search, Search Partners, Google Display Network	Supported
Shopping	Google Search, Search Partners	Supported
Performance Max	Google channels, Search Partners, Google Display Network	Supported
Demand Gen (in Korean)	Google channels, Google Display Network	Not supported (priority only)

In Google's announcement, the Google channels for Performance Max and Demand Gen are described as Google's own surfaces grouped together, such as Search, YouTube, Maps, Gmail and Discover.

Does this apply to your campaigns: scope and timeline

According to the Help article, the rollout starts on October 15, 2026 and continues in phases over several months, so the time when the settings card appears differs by account and campaign type. Country-level schedules have not been published. Support in the Google Ads API and Google Ads Editor is still in preparation, so for now you can manage it only in the Google Ads interface and Search Ads 360.

The first thing to check is any Search campaign with display expansion turned on. Google said on its official blog that from February 2027 the existing spend allocation setting for these campaigns goes away and is replaced by the new feature. After the switch, spend patterns may change, and Search campaigns that use a target impression share bidding strategy will stop serving on the Display Network. To keep the current pattern, Google advises setting the Display Network to low priority with a budget allocation of 50%.

For the basic rules of the daily budget itself, start with how to get started with Google Ads and how daily budgets work. Channel prioritization is the setting that splits that budget across surfaces.

Where to set channel prioritization and how to verify it

According to the Google Help article, you can set it at the account level and at the campaign level. You cannot set it in a manager (MCC) account. You have to do it in each client account or campaign.

1. Account level: Open the Channel Prioritization card in account settings, choose a campaign type, set the priority for each channel and save. The default for every channel is high.
2. Campaign level: Expand the Channel Prioritization card in the settings of the target campaign, choose Use campaign-level settings, set the priorities and save.
3. Enter a budget allocation for low-priority channels: You can enter a daily budget share only for channels you changed to low.

After saving, verify the result by comparing spend by network for the campaign. Check whether the spend share of the low-priority channel moves near the share you set, and whether conversions and cost per conversion have not changed much from the previous period. Because budget allocation is best-effort, it is normal for the share not to match exactly on a daily basis.

According to the Help article, if a campaign is not limited by budget, channel prioritization does not affect spend allocation. Even in that case, the budget allocation share still applies.

What to do now and what to watch next

If you have Search campaigns with display expansion, record the current Display Network spend share and cost per conversion now. You need to compare the same metrics after the February 2027 switch to tell whether a change came from the setting or from the market.

In Performance Max, you can set Google channels, Search Partners and the Display Network each to high or low. If you want to reduce the Display share, you can start by setting Display to low and allowing only a limited share.

Going forward, the supported campaign types and the API support timing may change in the Help article, so check the supported scope again before you configure anything.

There are three common mistakes. First, treating the budget allocation of a low-priority channel as a spend cap. It is best-effort, so daily spend can exceed the share you set, and accounts where the limit matters should check it directly in spend reports. Second, looking for the setting in a manager (MCC) account. The Help article says to set it in each client account or campaign. Third, changing only the priority in a campaign that is not limited by budget and expecting an effect. According to the Help article, priority does not affect spend allocation in that case.

One check you can try is a small comparison. Pick a single Search campaign with display expansion and, at the campaign level, set Display to low with a budget allocation of 50%. Then, for 1 to 2 weeks, put spend by network and cost per conversion side by side with the same earlier period. This gives you a preview of what could change at the February 2027 switch. This method is the author's recommendation and not a procedure from the Google Help article.

Google Ads channel prioritization FAQ

What happens if I do not touch channel prioritization?

The default for every channel is high, so the existing behavior stays in place. However, Search campaigns with display expansion are switched over automatically in February 2027.

If I set budget allocation to 0%, does the ad on that channel stop completely?

The Help article explains that a 0% setting means no spend on that channel. You can set it only on low-priority channels.

Can I use budget allocation in Demand Gen too?

No. Demand Gen supports priority only and does not support budget allocation.
