Google Ads Adds Channel Priority and Budget Caps: What Changes in 2027

On 14 October 2026 Google Ads announced two new spending controls: channel prioritization, which lets advertisers mark channels as High or Low priority, and channel-level budget allocation, which lets them cap how much of a daily budget a Low priority channel can take. The announcement on Google’s Ads & Commerce blog, written by Tal Akabas, Director of Product Management for Google Ads, covers Search, Shopping, Performance Max and Demand Gen campaigns.

For most advertisers this is an optional new setting. For one group it is not: anyone running a Search campaign with the Google Display Network switched on. Starting in February 2027, Google will move those campaigns onto the new controls and remove the spend arrangement they use today. In our experience, lead-generation accounts in Saudi Arabia, the UAE, Qatar and Egypt often have exactly that setup, sometimes without anyone remembering it was turned on. This piece explains what changed, what will change in February, and what to check now.

What Google announced

The new controls work at three levels: the account, a shared budget, or an individual campaign. According to the Google Ads Help article on channel prioritization and budget allocation, there are two tiers:

• High priority. Google’s bidding spends on these channels first, within your target if you use Target CPA or Target ROAS. By default, every channel is set to High priority.
• Low priority. Google aims to spend here after High priority channels. Google’s blog suggests that advertisers who had opted out of search partners or the Display Network can use this to test them with set limits instead of switching them off completely.

For Low priority channels you can add a daily budget allocation: a maximum percentage of the campaign’s average daily budget. The Help article’s own example is 5% of a $1,000 average daily budget, which means roughly $50 a day. Three details matter in practice:

• The cap is best-effort. Google says spend can occasionally exceed it.
• The allocation resets every day. Unspent or overspent amounts do not carry over.
• Setting the allocation to 0% stops spend on that channel.

Which channels you can control in each campaign type

The channels you can set differ by campaign type. In Performance Max and Demand Gen, Google groups its own surfaces (Search, YouTube, Maps, Gmail and Discover) into one grouping called “Google channels”, so you cannot, for example, rank YouTube above Gmail inside a Performance Max campaign. The table below follows the eligibility list in the Help article.

Some limits are worth knowing before you plan around the feature:

• Campaign total budgets: the settings work with campaign total budgets only in Demand Gen. In other campaign types, they do not apply to campaigns using a total budget.
• Manager accounts: you cannot set channel prioritization from a manager (MCC) account. It has to be set inside each client account or at campaign level.
• Tools: the settings can be managed in Google Ads and Search Ads 360. Google lists API and Google Ads Editor support as coming soon, so bulk changes through Editor are not yet an option.
• Experiments: the controls can be used in custom experiments, but multi-campaign shared budgets are not supported, and all channels in those experiments are treated as one priority tier.

Your bid strategy decides how much this matters

Priority is not a simple “spend here first” switch in every account. The Help article separates two situations.

• Target CPA, Target ROAS or Target CPC, not limited by budget. Prioritization has no effect, because the campaign is not short of money, but any allocation caps still apply. Google’s blog post makes a similar point: allocation is most useful for Target CPA or Target ROAS campaigns that are not limited by budget, where prioritization alone generally has little effect.
• Target CPA, Target ROAS or Target CPC, limited by budget. High priority channels spend first, within your target; budget moves to Low priority channels when they can meet the target.
• Maximize Conversions, Maximize Conversion Value, Maximize Clicks, Manual CPC and Target Impression Share. High priority channels are funded first, then Low priority channels.

So the first question for any account is simple: is the campaign limited by budget? If it is, priority changes where the money goes. If it is not, only the cap does.

The February 2027 change for Search campaigns with Display

Until now, Search campaigns with the Display Network turned on use what Google calls Display Expansion. Google’s Help page describes this as serving on the Display Network using unspent budget, with a 50% budget allocation applied in the backend. That split was not a setting advertisers could adjust.

The Help article states that starting in February 2027, all Search campaigns with Display Expansion enabled will automatically move to the new channel prioritization controls. The current spend allocation will be removed, and Google warns that spending across channels may shift. Three further points come from the same page:

1. To keep today’s behaviour, Google’s suggested setting is the Display Network at Low priority with a 50% daily budget allocation.
2. Target Impression Share campaigns will no longer serve on the Display Network once the change applies.
3. If you set priorities before February 2027, your new settings replace the current Display Expansion behaviour immediately. Until then, Search campaigns with Display on that have no priorities or allocations set keep working as they do now.

What lead-generation advertisers in the Gulf and Egypt should do now

The work is small but needs to be done account by account. A practical order:

1. Find every Search campaign with the Display Network included. In each campaign’s settings, check the Networks section (Google’s Display Expansion page describes it under Settings, then Networks; exact labels can differ as the interface changes). Note which campaigns use Target Impression Share, because those lose Display serving in February anyway.
2. Look at where the money and the leads came from. Use the “Network (with search partners)” segment in your campaign tables to compare Google Search, search partners and the Display Network. Look at cost per conversion, but then go further: of the conversions each network produced, how many became real quotation requests? If you have not separated real inquiries from noise in your tracking, start there; our guide to GA4 key events for lead tracking covers the setup.
3. Check whether the campaign is limited by budget. As explained above, this decides whether priority changes anything or whether you need a cap.
4. Choose a setting deliberately. For example, a distributor whose Display conversions rarely turn into quotations might set Display to Low priority with a small cap, or 0%, and keep Search at High. An advertiser whose Display traffic does produce qualified inquiries can keep the 50% equivalent, or test a higher or lower figure.
5. Treat search partners the same way. Search partners can now be set to Low priority with a cap instead of being switched fully on or off. That is a cleaner way to test them on a small share of budget.
6. Record what you changed and when. Because new settings apply immediately, any change in cost or lead volume afterwards needs a date to be compared against. Note it in your reporting so the next monthly review reads the numbers correctly.
7. Agencies and in-house teams with several accounts: because the setting cannot be applied from a manager account and Editor support is not yet available, allow time to set it in each account individually.

Accounts running Performance Max alongside Search should review both together. Performance Max can also serve on search partners and the Display Network, and because shared budgets must link campaigns of the same type, a cap set on a Search campaign does not limit a Performance Max campaign, or the other way round.

Is the setting in your account yet?

Google’s blog says these optional features are rolling out to Search, Shopping, Performance Max and Demand Gen “over the next months”, and describes the rollout as global. The Help article dates eligibility from 15 October 2026, describes the rollout as progressive, and notes that availability may vary by account. Google has not published a country-by-country timetable, so there is no official confirmation of when accounts in Saudi Arabia, the UAE, Qatar or Egypt will see it.

The quickest check is in the account itself. According to the Help article, at account level the control appears as a Channel Prioritization card in Account settings; at campaign level it sits in the campaign’s Settings, where choosing “Use campaign-level settings” overrides the account default. Labels may differ slightly while the rollout continues. If neither appears yet, the February 2027 migration still applies to your Search campaigns with Display on, so it is worth doing the analysis in steps 1 to 3 now and applying the setting once it arrives.

If your Search account is built around a small number of high-value queries, as many B2B accounts in the region are, our earlier piece on winning low-volume, high-value Search queries explains why keeping budget on Google Search matters. RX’s performance marketing team reviews these settings as part of campaign management. Whatever you decide, record each Search campaign’s current network settings and lead quality by network now, so that after February 2027 you can see whether spend shifted and whether the leads changed with it.
