Google Ads channel prioritization: what High and Low priority mean, and how Indian advertisers should set them

What channel prioritization is, in one paragraph

Channel prioritization is a new Google Ads control, available from 15 October 2026 and rolling out in stages, that lets you mark each channel in a campaign as High or Low priority. Google spends on High priority channels first and sends only the leftover budget to Low priority ones, and for Low priority channels you can set a percentage cap on daily spend. It gives you a middle path between leaving search partners and Display fully on and switching them off.

Google announced the change on its Ads and Commerce blog on 14 October 2026, saying marketers want more transparency and choice over how their budgets are directed. The detail sits on the Google Ads Help page for channel prioritization and budget allocation, which this guide follows. Rollout is progressive, so if you cannot see the setting yet, check again in a few weeks.

Who this is for: founders, marketing heads and business owners who pay for Google Ads, or who pay an agency to run it, and need to decide what to do with the new setting before the end of the year. If you are new to Google Ads, start with our beginner setup guide and come back.

What actually changes in your account

Until now, the choices for networks were mostly on or off. Search campaigns could include search partners and the Display Network, and the only way to stop spend on them was to opt out. Now each eligible channel gets a priority level.

• High priority is the default for every channel. Google spends here first, within your target if you use Target CPA or Target ROAS.
• Low priority means Google aims to spend on that channel after High priority channels. Google suggests using it for channels you value less, instead of opting out.
• Daily budget allocation is an optional percentage for a Low priority channel. It is a best effort limit applied to the campaign’s average daily budget. Google’s own example: 5% of a $1,000 average daily budget is about $50 a day.
• 0% on a Low priority channel means Google will not spend on it.

You can set this at account level (Account settings, "Channel Prioritization" card) or override it for one campaign (campaign Settings, "Channel Prioritization" card, then "Use campaign-level settings"). An account default applies to every eligible campaign of that type unless you override it.

How your bid strategy changes what the setting does

This is the part most advertisers will miss, and it decides whether the setting does anything for you.

In plain words: if your campaign already hits its target and your daily budget is not the constraint, flipping Display to Low will not move much money. Only a cap, for example 10% on Display, will. If your budget is the constraint, priority decides who gets fed first.

A worked example for a Chennai service business (illustrative)

These numbers are assumptions to show the method. They are not benchmarks, and your own account data should replace them.

A diagnostic centre in Chennai runs one Search campaign for health check packages with an average daily budget of ₹3,000 on Maximize Conversions. Display Expansion is on. Over the last 30 days the team exports the network report and, using its own call and form tracking, finds this (assumed):

Display took 30% of spend and produced one booked test. The decision is not to switch Display off blindly, because some partner and Display traffic can assist later bookings. It is to turn that guess into a test:

1. Keep Google Search at High priority.
2. Set search partners to Low priority with a 10% allocation, which is about ₹300 a day on a ₹3,000 budget.
3. Set the Display Network to Low priority with a 5% allocation, about ₹150 a day.
4. Run it for four weeks, then compare cost per booked test by channel.

The test caps the downside at roughly ₹450 a day in lower quality channels while the rest of the budget goes where bookings have come from. If after four weeks Display still produces nothing, set it to 0%. If it produces cheap assisted bookings, raise the cap in small steps. Either way the decision comes from your data, not from a default.

The February 2027 change you must plan for

Per Google’s help page, Search campaigns using Display Expansion that have not set priorities or allocations keep current behaviour until February 2027. From February 2027 they migrate automatically to the new controls, which may shift spend between Search, search partners and the Display Network. Google also says the Display Network will no longer serve on Search campaigns that use the Target Impression Share bid strategy.

If you set priorities before February 2027, the new settings apply immediately and replace Display Expansion budget behaviour. To keep your current setup, Google advises setting the Display Network to Low priority with a 50% daily budget allocation, best effort.

Which setting for which situation

How to judge a channel properly

Google Ads reports conversions, but you decide what counts. Before touching priority levels, make sure the numbers behind the decision are honest.

1. Count qualified enquiries, not clicks. A call under 10 seconds, a spam form or a job seeker is not a lead. Our checklist on ads that get clicks but no leads shows how to separate them.
2. Follow enquiries to customers. Cost per enquiry can look healthy while cost per customer is poor. A system such as Be12 CRM keeps the source with every call, form and WhatsApp conversation and records what each became.
3. Use enough data. Two bookings from a channel is noise. Wait for a few weeks of data or enough conversions before you cut or scale.
4. Remember assisted value. Display and partner traffic can show up early in a journey. Compare conversions with and without the channel during the test, not only last click numbers.
5. Change one thing at a time. If you change priorities, bid strategy and budget in the same week, you will not know what worked. Our comparison of Meta and Google Ads covers where search budgets fit alongside social.

If your cost per customer matters more than cost per lead, work backwards from your CAC payback period: a channel that cannot pay back inside your ceiling gets the lowest cap or none.

Limitations to know before you promise anything

• Not a guarantee. Allocations are best effort. Spend can exceed the percentage on a given day, and allocations reset daily with no carry over.
• Shared budgets. Linked campaigns must be the same campaign type, and the allocation applies to the shared budget as a whole.
• Experiments. Multi-campaign shared budgets are not supported in custom experiments, and all channels in an experiment share one priority tier.
• Manager accounts. You cannot set prioritization from a manager account. Agencies have to set it inside each client account or at campaign level.
• Tools. Available in Google Ads and Search Ads 360 now. Google Ads API and Google Ads Editor support is described as coming soon, so scripts and bulk editors will not set it yet.
• Rollout. It rolls out progressively and availability can vary by campaign type.

The 30 minute checklist

Use this checklist this week. It works for an in-house team or when you review an agency’s work.

1. Open Account settings and look for the Channel Prioritization card. If it is not there yet, note the date and check again.
2. List every Search campaign with Display Expansion on and every Performance Max campaign, with its bid strategy and daily budget.
3. Export the last 30 to 90 days of spend and conversions by network.
4. Confirm that calls, forms and WhatsApp clicks are tracked as conversions, and that you can tell qualified enquiries from junk.
5. Decide per campaign: High, Low with a cap, or Low at 0%.
6. If a campaign has Display Expansion and you want today’s behaviour after February 2027, set Display to Low with a 50% allocation.
7. Write the date, the old and new settings, and the expected effect in a change log.
8. Review after four weeks against cost per qualified enquiry and cost per customer.
9. If an agency manages the account, ask them for the settings per campaign and the review date. Our guide to choosing a digital marketing agency lists what good reporting looks like.

Common mistakes

• Setting everything to Low priority and expecting spend to drop. High and Low only decide the order of funding.
• Ignoring the percentage on campaigns that already hit their target.
• Switching off partners or Display for good after a week of thin data.
• Letting the February 2027 migration happen without a decision.
• Judging by cost per lead when sales quality differs by channel.

What to do next

Treat the new controls as a test, not a verdict. Cap the weak channels, keep your best intent traffic fully funded, and review with customer numbers. If you want a second pair of eyes on your account before February, our performance marketing team can run the audit and set up the test.
