On 14 October 2026 Google announced two optional controls for Search, Shopping, Performance Max and Demand Gen campaigns. Channel prioritization lets advertisers mark channels as high or low priority, so that with Target CPA or Target ROAS bidding the high-priority channels are fully funded within target before any budget goes to low-priority ones. Budget allocation lets a low-priority channel be capped at a maximum share of daily budget, on a best-effort basis. Both are rolling out over the next months at account and campaign level, including shared budgets. From February 2027, the existing spend split for Search campaigns running the Google Display Network is removed.

What changed

Until now, a campaign that spanned several networks spent wherever the bidding system found conversions, and the only way to protect or limit a channel was to split it into its own campaign or ad group, which Google’s own Demand Gen channel controls page notes may reduce efficiency. The announcement adds two layers of control inside one campaign.

Channel prioritization. Channels or channel groupings get a High priority or Low priority label. With Target CPA or Target ROAS, high-priority channels are funded in full, within their target, before the remainder flows to low-priority channels. On Search campaigns, Google Search, Search partners and the Google Display Network can each take a different priority. In Performance Max and Demand Gen, Search, YouTube, Maps, Gmail and Discover are grouped as “Google channels,” with the Display Network as the other tier. Priorities can be set separately for Search, Shopping, Performance Max and Demand Gen, at account and campaign level, and they apply to shared budgets.

Budget allocation. For a channel marked low priority, you can set a maximum percentage of daily budget to spend there. Google says its tools aim to keep spend within the limit but do not guarantee it. Google adds that this is most useful for Target CPA or Target ROAS campaigns that are not budget-limited, where prioritization alone has little effect, and suggests it as a way to test Search partners or the Display Network with a ceiling rather than opting out.

The February 2027 change. Starting February 2027, the current spend allocation setup for Search campaigns with the Display Network on will be removed, and channel spend may shift. To keep the current configuration, Google says to set the Display Network to low priority with a 50% budget allocation. The announcement carries no performance figures and no footnotes.

Why it matters

This is the control Performance Max advertisers have asked for since launch, arriving by a side door. The question “how much of my PMax budget went to Display versus Search” has never had a clean answer and still does not, but “do not let Display take more than a fifth of it” now has one. For Search campaigns, it ends the choice between Display on and Display off. For Demand Gen, it replaces the workaround of isolating a channel in its own ad group with a higher target.

The February date is the item with a deadline. Any Search campaign with the Display Network enabled has an implicit allocation today that Google is deleting; if nobody sets the 50% low-priority rule, spend “may shift,” which in practice means Display can take more. Our view: audit those campaigns now, decide per campaign whether Display earns its place, and either turn it off or set the 50% cap before the rollout reaches the account. Treat the caps as best-effort, as Google says; a 20% cap is a target, not a wall, and reporting by network is still the check.

What to do

In Campaigns, filter Search campaigns with the Google Display Network enabled and segment by network to see what Display currently takes. Decide per campaign: off, or low priority at 50%, before February 2027.
When the controls reach the account, set account-level defaults first, then override at campaign level only where a campaign has a different purpose.
For Performance Max and Demand Gen, mark Google channels high priority and the Display Network low priority with a cap that matches what the network has historically earned, then review the network segment weekly.
Use a cap, not an opt-out, to test Search partners or the Display Network on campaigns that have never run them; set the cap low and compare conversion rate by network after two weeks.
Keep Target CPA or Target ROAS on campaigns where you want prioritization to bite; Google says it has little effect on campaigns that are not budget-limited without a cap.

Still unknown

Google gives no rollout dates per campaign type or account, no day in February 2027, and no detail on how prioritization behaves with Maximise conversions bidding. The new help page is linked from the announcement but we have not reviewed it yet. We have not seen the controls in an account; the network-segment checks above are how we would verify them.

Frequently asked questions

What is channel prioritization in Google Ads?

An optional control, announced 14 October 2026, that lets you mark channels or channel groups as high or low priority. With Target CPA or Target ROAS, high-priority channels are fully funded within their target before remaining budget goes to low-priority channels. It applies to Search, Shopping, Performance Max and Demand Gen at account and campaign level.

Can I cap how much a Google Ads campaign spends on the Display Network?

Yes, once the controls reach your account. Set the Display Network to low priority and choose a maximum percentage of daily budget for it. Google describes the cap as best-effort rather than guaranteed.

What changes for Search campaigns with the Display Network in February 2027?

Google says the current spend allocation setup for Search campaigns with the Display Network on will be removed and channel spend may shift. To keep today’s configuration, set the Display Network to low priority with a 50% budget allocation before then.

Which channels count as Google channels in Performance Max and Demand Gen?

Search, YouTube, Maps, Gmail and Discover are grouped together as “Google channels” for prioritization. The Google Display Network is the separate channel that can be set to a different priority.
