After Google Added Channel Prioritization: What Should You Set First?

Google Ads is rolling out channel prioritization and channel-level budget allocation across Search, Shopping, Performance Max, and Demand Gen. The first setting to get right is not a blanket “High priority everywhere.” Inventory which campaigns already expand to Search partners or the Google Display Network, decide what you want to protect before the February 2027 Display Expansion migration, then use Low priority plus a percentage budget allocation when priority tiers alone will not reshape spend.

This article gives you a practical Channel Control Ladder, a Channel Fit Scorecard, and a worked example so you can configure the new controls without guessing.

Key takeaways

• As of October 15, 2026, Google is progressively rolling out High/Low channel priorities and optional daily budget allocation percentages for Search, Shopping, Performance Max, and Demand Gen.

• High-priority channels are funded first (within target when you use Target CPA or Target ROAS). Low-priority channels get remaining budget, and you can optionally cap them as a percentage of average daily budget on a best-effort basis.

• If a Target CPA / Target ROAS / Target CPC campaign is not limited by budget, priority tiers generally do not change spend distribution—budget allocation still applies.

• Starting February 2027, Search campaigns with Display Expansion automatically migrate to the new model. To keep a continuity-like setup, set the Google Display Network to Low priority with a 50% daily budget allocation before that change takes effect.

• After the migration, the Google Display Network will no longer serve on Search campaigns that use Target Impression Share. Plan a separate display path for those campaigns if display reach still matters.

What changed—and what did not

Google’s October 14, 2026 product announcement framed the update as an alternative to all-or-nothing network opt-outs. Instead of leaving Search partners or the Google Display Network fully on or fully off, you can rank channels as High or Low priority and, for Low-priority channels, set a maximum share of average daily budget.

According to Google Ads Help, available channel options by campaign type are:

• Search: Google Search, search partners, Google Display Network

• Shopping: Google Search, Google search partners

• Performance Max: Google channels, Google search partners, Google Display Network

• Demand Gen: Google channels and Google Display Network for prioritization; budget allocation is not supported

In Performance Max and Demand Gen, Google surfaces such as Search, YouTube, Maps, Gmail, and Discover are grouped together as Google channels. That grouping is a real control limit: if you need finer opt-outs inside Google inventory, Google’s Help guidance points you toward Search or Demand Gen structures rather than expecting PMax to expose every surface separately.

Defaults matter. All channels start as High priority. Settings can be set at account, shared-budget, or campaign level, with campaign or shared-budget overrides replacing account defaults. Manager accounts cannot set channel prioritization for clients; each client account must be configured directly.

The Channel Control Ladder

Use this sequence instead of flipping every Low/High toggle on day one.

L0 — Inventory before you change anything

Export or filter campaigns by type, network settings, bid strategy, shared budgets, and whether the campaign is limited by budget. Flag every Search campaign with Display Expansion enabled. Flag every Target Impression Share Search campaign that currently includes Display. Note shared budgets that mix priorities across several campaigns of the same type—allocation applies to the shared pool as a whole.

L1 — Protect continuity where Display Expansion already runs

Until February 2027, Search campaigns with Display Network enabled that have not set channel priorities or budget allocation continue under current Display Expansion behavior. Once you set the new controls, those settings apply immediately and replace the older Display Expansion budget behavior.

If your goal is continuity—not a redesign—set Google Display Network to Low priority with a 50% daily budget allocation. Google states that configuration as the way to keep the current-like setup after the February 2027 automatic migration. Treat that 50% as a best-effort daily upper bound based on average daily budget, not a hard guarantee and not a percentage of yesterday’s actual spend.

L2 — Protect primary intent channels

For most lead-gen and ecommerce Search campaigns, keep Google Search on High priority. Move Search partners and/or Display to Low priority when historical placement or network reports show weaker efficiency, noisier query matching, or brand-risk inventory you do not want funded first.

For Maximize Conversions, Maximize Conversion Value, Maximize Clicks, Manual CPC, and Target Impression Share, Help documentation says High-priority channels spend first; remaining budget can move to Low-priority channels when High-priority inventory cannot fully use the budget. For budget-limited Target CPA / Target ROAS / Target CPC, High-priority channels spend first within target, and leftover opportunity can shift toward Low-priority channels that can still meet the target—still subject to any Low-priority budget allocation.

L3 — Controlled re-entry instead of permanent opt-outs

If you previously turned Search partners or Display off entirely because spend drifted, Low priority plus a small allocation percentage is usually a better experiment design than remaining opted out forever. Start with a tight percentage of average daily budget, review network and placement performance over one to two conversion cycles, then raise, lower, or return to 0%.

A 0% Low-priority allocation tells Google not to spend on that channel. That is useful when you want the channel visible in settings for future tests without funding it today.

L4 — Split structure when priority groups are too coarse

Channel prioritization is not a substitute for campaign architecture. If Performance Max’s bundled “Google channels” grouping blocks the surface control you need, or if Target Impression Share Search campaigns will lose Display delivery after February 2027, move display or demand-generation reach into a dedicated campaign type rather than forcing one campaign to do every job.

Channel Fit Scorecard

Score each factor from 0 to 2. Higher totals usually mean you should act sooner and be more conservative with Low-priority caps.

How to read the score

• 0–4: Wait for controls in your account if they are not visible yet; document defaults and revisit after rollout.

• 5–8: Complete L0–L2 now. Preserve Search Display Expansion continuity where it matters; keep Search High; add modest Low-priority caps only where evidence is clear.

• 9–12: Treat this as an operating-change project. Preserve continuity settings, schedule Target Impression Share display coverage separately, and decide whether PMax needs companion Search or Demand Gen campaigns for finer control.

Worked example: $1,000/day Search campaign with Display Expansion

Hypothetical example: A regional services company runs a Search campaign at a $1,000 average daily budget with Maximize Conversions, Display Expansion on, and Search partners on. Network reports show Google Search drives most qualified leads. Search partners are mixed. Display contributes incremental volume at a weaker sales-accepted lead rate.

Recommended first configuration:

1. Google Search: High priority

2. Search partners: Low priority with a 10% allocation ($100/day best-effort ceiling)

3. Google Display Network: Low priority with a 50% allocation if continuity with prior Display Expansion behavior is the goal, or a tighter percentage if Display is only a test lane

Why this order works: Maximize Conversions will still try to spend the budget efficiently, but High-priority Search gets first claim. Partners stay available without unlimited first access. Display keeps an intentional ceiling. Because budget allocation is calculated from average daily budget, the 10% partner cap means Google aims to keep partner spend at or below about $100 that day—not 10% of whatever the campaign happened to spend by noon.

If the same campaign used Target CPA and was not limited by budget, changing partners and Display to Low priority alone would typically not reshape spend much. In that case the meaningful control is the Low-priority budget allocation percentage, not the priority label by itself.

Common failure patterns

• Setting priorities before inventorying Display Expansion. Early edits replace current Display Expansion budget behavior immediately. If you wanted continuity, start with Low + 50% for Display rather than improvising.

• Expecting High/Low labels to fix non-budget-limited Target CPA/ROAS. Google’s Help table is explicit: priority generally does not redistribute spend there; allocations still do.

• Treating percentage caps as hard daily guarantees. Allocations are best-effort, reset daily, and do not carry over underspend or overspend.

• Ignoring Target Impression Share Search campaigns. After the February 2027 change, GDN no longer serves on those campaigns. Continuity settings will not preserve Display there.

• Assuming Demand Gen supports the same budget-allocation lever. Prioritization is available; budget allocation is not.

• Applying one account default blindly across every campaign type. Account defaults are useful, but Search Display Expansion continuity, Shopping partner tests, and PMax partner/Display caps often need campaign-level overrides.

Limitations and exceptions

Feature availability can vary by account and campaign type during rollout. Google Ads API and Editor support for configuring these controls is described as coming soon in Help documentation, so many teams will configure them in the Google Ads UI or Search Ads 360 first.

Campaign total budgets are supported with channel prioritization for Demand Gen only; for other campaign types, prioritization settings do not apply to campaigns using campaign total budgets. Shared-budget campaigns must share the same campaign type for these settings to apply, and the shared budget is treated as one pool.

These controls improve steering. They do not guarantee that every Low-priority channel will stay under the percentage every day, and they do not replace conversion tracking quality, negative keywords, creative strength, or landing-page fit.

Recommended next steps

1. Complete the Channel Fit Scorecard for your top spend campaigns.

2. List Search campaigns with Display Expansion and Target Impression Share separately.

3. Where continuity matters, set Display to Low priority with a 50% allocation before February 2027—or accept that automatic migration may shift channel mix.

4. For non-budget-limited Target CPA/ROAS campaigns, put the real constraint on Low-priority budget allocation percentages rather than priority labels alone.

5. Review network reports after one to two conversion cycles before widening caps or turning previously opted-out networks back on at scale.

If you want help mapping these controls across Search, Shopping, Performance Max, and Demand Gen without disrupting peak-season delivery, Oasbit’s digital advertising services include bid-strategy and network-structure reviews tied to business capacity—not template toggles.
