Google Ads Channel Prioritization and Budget Allocation: What Kolkata Advertisers Should Do Now

Google Ads now lets you mark each ad channel as “High priority” or “Low priority” and cap how much of your daily budget the low-priority channels can spend. Announced on 14 October 2026 and rolling out progressively across Search, Shopping, Performance Max and Demand Gen, these controls replace the old all-or-nothing choice for Search partners and the Display Network. If you handle Google Ads management in Kolkata or anywhere in India, review your settings now, because Search campaigns using Display Expansion will be migrated automatically in February 2027.

What are Google Ads channel prioritization and budget allocation?

Until now, most advertisers had two options for networks such as Google search partners and the Google Display Network (GDN): leave them on and let Google decide the split, or switch them off completely. In Google’s channel prioritization announcement, Google describes two new optional controls that sit between those extremes.

Channel prioritization

You place each channel in one of two tiers. Campaigns fully fund “High priority” channels first (within your target, if you use Target CPA or Target ROAS) and only then send the remaining budget to “Low priority” channels. By default, every channel is set to High priority, so nothing changes until you act.

• In Search campaigns, Google Search, Search partners and the GDN can each sit in a different tier.
• In Performance Max and Demand Gen, Google-owned surfaces such as Search, YouTube, Maps, Gmail and Discover are grouped together as “Google channels”.
• Priorities can be set at the account level, the shared budget level or the campaign level.

Budget allocation

For any Low priority channel, you can also enter a maximum percentage of the campaign’s average daily budget. Google’s own example: a 5% allocation on a $1,000 average daily budget means the system aims to keep that channel at or below $50 a day. In rupee terms, a 5% allocation on a ₹20,000 average daily budget would aim to keep that channel at or below ₹1,000 a day.

Three details matter here:

• The percentage is of the average daily budget, not of what the campaign actually spends.
• It works on a best-effort basis, so a channel can occasionally go over the limit.
• The allocation resets every day, and unspent or overspent amounts do not carry over.

Setting a Low priority channel to 0% tells Google not to spend on it at all, which gives you an opt-out from the same screen.

Which campaign types and channels are covered?

According to the Google Ads Help Center guide to channel prioritization, the controls became progressively available from 15 October 2026, and availability in your account may vary by campaign type and rollout timing.

Campaign type	Channels you can prioritise	Budget allocation supported?
Search	Google Search, Google search partners, Google Display Network	Yes
Shopping	Google Search, Google search partners	Yes
Performance Max	Google channels, Google search partners, Google Display Network	Yes
Demand Gen	Google channels, Google Display Network	No (prioritization only)

You can manage these settings in Google Ads and Search Ads 360. Google says support for the Google Ads API and Google Ads Editor is coming soon, so bulk changes through scripts or Editor will have to wait.

How do the new controls work with your bid strategy?

This is the part most advertisers will misread. Channel prioritization only changes behaviour when a campaign is limited by budget. Budget allocation, on the other hand, applies either way.

• Target CPA, Target ROAS or Target CPC, not limited by budget: Google aims to hit your target across all channels, so priority tiers generally make no difference. Any budget allocation you set on Low priority channels still applies.
• Target CPA, Target ROAS or Target CPC, limited by budget: High priority channels spend first, within your target. Budget moves to Low priority channels only when they can deliver conversions at your target, and their spend stays within any allocation you set.
• Maximize Conversions, Maximize Conversion Value, Maximize Clicks, Manual CPC and Target Impression Share: High priority channels spend first. Only budget that cannot be spent on them flows to Low priority channels.

In practice, if your tCPA or tROAS campaigns rarely hit their daily budget, the percentage cap is the lever that actually controls Search partner or GDN spend.

What changes in February 2027 for Search campaigns with Display Expansion?

Starting in February 2027, every Search campaign with Display Expansion enabled will migrate automatically to channel prioritization and budget allocation. The current spend allocation setup will go away, and Google warns that you may see spend shift between Google Search, Search partners and the GDN.

• To keep roughly today’s behaviour, Google suggests setting the GDN to “Low priority” with a 50% daily budget allocation.
• As part of the change, the GDN will no longer serve on Search campaigns that use the Target Impression Share bid strategy.
• If you set channel priorities on a Search campaign before February 2027, the new settings apply immediately and replace the old Display Expansion behaviour.

What limitations should you check before switching it on?

• Campaign total budgets: channel prioritization works with campaign total budgets only in Demand Gen. In other campaign types, the settings will not apply to campaigns using total budgets.
• Shared budgets: all campaigns on a shared budget must be the same type (all Search or all Shopping, for example), and the allocation then treats the shared budget in Google Ads as one pool.
• Experiments: you can use the controls in custom experiments, but multi-campaign shared budgets are not supported there.
• Manager accounts: you cannot set priorities from an MCC. Agencies and in-house teams with several accounts must configure each client account or campaign directly.

What does this mean for Google Ads management in Kolkata and across India?

For businesses in Kolkata, West Bengal and the rest of India, the update matters most for three kinds of advertisers: lead-generation businesses that switched off Search partners or the GDN, e-commerce brands running Performance Max through peak seasons, and small accounts where every rupee of budget has to be justified.

Lead-generation businesses

Think of a coaching institute in Salt Lake, a diagnostic clinic in South Kolkata or a New Town real estate project collecting enquiries through Search ads. If you turned off Search partners because the enquiries looked weak in your CRM, you can now bring that inventory back as Low priority with a small cap, such as 5–10%, and judge it on qualified leads rather than form fills. Feeding offline lead outcomes back into Google helps here, and our article on Google Ads Confidential Matching for first-party data explains a privacy-friendly way to do it.

E-commerce and D2C brands

A Kolkata saree, sweets or home décor brand running Performance Max can now keep Google channels as High priority while limiting the GDN to a defined share of the daily budget. During festive and wedding-season sales, when budgets are tight and demand on Search is high, that keeps money flowing to the surfaces where buyers are actively searching. Our team handles this kind of channel-level budgeting as part of performance marketing services in Kolkata.

Small and mid-sized accounts

Many local advertisers run daily budgets of a few thousand rupees. On such budgets, a percentage cap is easier to manage than switching networks on and off every few weeks. Combined with AI-driven matching, it also gives you a cleaner way to test reach. If you are already using AI Max, read our AI Max for Search setup guide before you change channel settings, so you do not change two variables at once.

A step-by-step plan for the next 30 days

1. Audit network performance. In each Search campaign, segment results by network (with search partners) and compare cost per qualified lead or ROAS for Google Search, Search partners and the GDN over the last 60–90 days.
2. Check conversion quality first. Make sure you are counting real outcomes, such as qualified leads, calls or purchases, not page views. If the landing page itself is leaking enquiries, landing page conversion optimisation will do more for results than any channel setting.
3. Set account-level defaults. Go to Account settings, open the “Channel Prioritization” card, choose the campaign type and assign tiers. Use campaign-level overrides only where a campaign genuinely needs different treatment.
4. Test, do not switch. For networks you had opted out of, try Low priority with a small allocation for two to four weeks instead of turning them fully on.
5. Review weekly. Because the cap is best-effort, check daily spend by network and adjust if a channel keeps going over.
6. Plan for February 2027. List every Search campaign using Display Expansion and decide now whether to keep the 50% GDN setup, reduce it or set it to 0%.
7. Document it per account. Since MCC-level settings are not available, keep a simple sheet of priorities and caps for every client or brand account.

Local retail and franchise brands using AI Max for Local campaigns can pair this with the steps in our guide to AI Max for Indian retail and franchise brands.

Should you set channel priorities now or wait?

If a campaign is limited by budget and you already know which networks perform best, set priorities now. You get control before the year-end and festive peaks, and you avoid a surprise shift in spend when the February 2027 migration happens. If your tCPA or tROAS campaigns are not limited by budget, priorities alone will not change much, so focus on budget allocation percentages instead. Either way, change one thing at a time and give each test enough data before you judge it.

If you would rather have a specialist set this up, our Google Ads and Meta Ads team can audit your network split and recommend tiers and caps for each campaign.
