Google Ads October 2026: New Channel Prioritization Controls Give Ecommerce Brands Budget Precision They've Never Had

Oct. 14 2026

On October 14, 2026, Google announced Channel Prioritization and Budget Allocation, two new controls rolling out globally across Search, Shopping, Performance Max, and Demand Gen campaigns. For ecommerce brands running Search campaigns with the Display Network enabled, there is a concrete February 2027 deadline: if you take no action in the next four months, your spend allocation between Search and Display will reset and could shift in ways you did not choose.

What Does Google's Channel Prioritization Mean for Your Campaigns?

Every channel in your Google Ads account now defaults to "High priority," meaning nothing changes automatically on day one. But that default is what makes the February 2027 change dangerous for brands who ignore it. Google will retire the existing Display Network spend controls in Search campaigns, and accounts that do not configure the new channel priority settings will lose the current Search-first behavior that was previously baked in.

Google Ads channel prioritization and budget allocation controls for ecommerce brands

How Does Google Channel Prioritization Actually Work?

The new system lets you label each channel within a campaign as "High priority" or "Low priority." Google's AI will fund high-priority channels first, working toward your Target CPA or Target ROAS, before allocating remaining budget to lower-priority inventory.

What you can control depends on your campaign type:

  • Search campaigns: You can set Google Search, Google Search Partners, and the Google Display Network as separate priority tiers. This is the most granular control and the most urgently relevant for ecommerce advertisers running all three networks by default.
  • Performance Max and Demand Gen: Google-owned channels (Search, YouTube, Discover, Gmail, Maps) are grouped together. You cannot prioritize those individual placements, but you can control how much budget flows to lower-priority partner inventory within those campaign types.

Settings apply at the account level, the campaign level, or to shared budgets. Campaign-level settings override account-level defaults. API support is available at launch. For Demand Gen campaigns specifically, Google will begin limited testing of these features in November 2026.

What Is the Budget Allocation Feature and Why Does It Matter for Ecommerce?

Channel prioritization alone does not limit spending on a channel. It only sets the sequence in which Google funds them. For Target CPA and Target ROAS campaigns that are not budget-constrained, prioritization will have minimal impact unless you pair it with Budget Allocation.

Budget Allocation lets you put a percentage cap on how much of your daily budget can be spent on a low-priority channel. You set the percentage, and Google will aim to stay within that limit on a best-effort basis. It is not a hard cap. But it is the mechanism that gives you real control over what flows where.

The 0% option is significant: setting a channel to 0% prevents any spend on that channel entirely, without needing to remove it from your campaign. For brands that want to test Search Partners cautiously, or that have historically seen poor return from Display within Search campaigns, this is a practical tool that did not exist before October 2026.

The February 2027 action is specific: if you currently run Search campaigns with the Display Network enabled, Google recommends setting the Display Network to "Low priority" with a 50% budget allocation. That recreates the current Search-first behavior. If you skip this step, your Display spend share could increase without any deliberate choice on your part.

"Starting in February 2027, the current Display spending allocation setup in Search campaigns will go away. Advertisers who do not act could see spend shift between networks." -- Google Ads product team

Who Is Most at Risk from the February 2027 Change?

Brands running Search campaigns with "Search and Display Select" or any configuration that includes the Display Network are the direct audience for this deadline. If your campaigns target both networks, and your current performance benchmarks assume the existing Search-first behavior, the February reset could cause your Display spend to increase and your ROAS to shift in ways your reporting will not immediately explain.

Brands running Search-only campaigns with no Display or Search Partner expansion are not affected by the February 2027 change, but they can still benefit from the prioritization controls for Search Partner traffic quality management.

What Should You Do Now with Google's Channel Prioritization Update?

  1. Audit every Search campaign with Display Network enabled. Go to your campaign settings, look for any campaign running "Search Network with Display Select" or any configuration that includes the Display Network. These are the campaigns the February 2027 change directly affects. Flag them now.
  2. Set the Display Network to "Low priority" with 50% budget allocation. When Channel Prioritization rolls out to your account, this is the configuration Google recommends to maintain your current spend behavior. Do not wait until February to set this up.
  3. Use the 0% option for channels you want to stop testing. If your Search Partners traffic has historically underperformed, set it to Low priority with 0% allocation. You eliminate the spend without removing the network from your campaign structure.
  4. Configure account-level defaults now. The controls work at the account level, so you can set your preferred defaults across all campaigns at once. Then override at the campaign level where your strategy differs from the default.
  5. Watch for Demand Gen rollout in November. Google is limiting Channel Prioritization testing for Demand Gen until next month. If you run Demand Gen campaigns, plan to revisit these settings in November when the feature becomes available for that campaign type.

Frequently Asked Questions

Does Channel Prioritization affect my Performance Max campaigns?

Yes, but with less granularity than Search. In Performance Max, Google groups its owned channels (Search, YouTube, Discover, Gmail, Maps) together, so you cannot prioritize those placements individually. You can control how budget flows to lower-priority partner inventory within PMax, but you cannot separate YouTube from Search as distinct tiers.

Is the budget allocation percentage a hard cap?

No. Google aims to stay within your specified percentage on a best-effort basis, but it is not a guaranteed hard cap. The control is most useful as a guardrail to limit how much test spend goes toward lower-priority channels, not as a strict firewall. If you need to fully block a channel, set the allocation to 0%.

What happens to my Search campaigns in February 2027 if I take no action?

Google will retire the current Display Network spending allocation setup in Search campaigns. Since the new system defaults all channels to "High priority," advertisers who do not configure channel priorities could see their Display spend increase relative to Search. This is the primary reason Google recommends setting Display to "Low priority" with 50% budget allocation before February 2027.

Can I use Channel Prioritization with shared budgets?

Yes. The channel prioritization and budget allocation controls work with shared budgets as well as individual campaign budgets. You can set preferences at the account level as defaults and override them at the campaign level where your strategy differs.

Is Your Google Ads Budget Going Where You Think It Is?

Most ecommerce brands running Search campaigns today have no clear visibility into how much of their budget is flowing to the Display Network versus Google Search. This update gives you the controls to fix that before February 2027 forces a default that may not match your strategy. At Common Thread Collective, we audit channel-level spend allocation as part of every account review for 7-9 figure ecommerce brands.
