You can finally cap how much Google spends outside of Search

You set up a Google Ads campaign so that someone with a leak searches for a plumber, finds you and calls.

Depending on how the campaign was built, part of that budget could also go to banner ads on websites and apps, or to search engines that partner with Google. Until now, those were mostly all or nothing. This week Google added a dial.

What happened

On October 14, Google announced two new controls in a post titled "Guide your campaign spending with new priority and allocation features," written by Tal Akabas, Director of Product Management, Google Ads. Google's help page says that "Starting on October 15, 2026, Channel Prioritization and budget allocation controls will progressively become available." So this is live and rolling out, but it may not be in your account yet. Google says availability can vary by account.

Here is how it works, per Google's help page:

• With channel prioritization, you mark each channel as High or Low priority. Google funds High priority channels first and sends what is left to the Low ones.
• With budget allocation, you can cap a Low priority channel as a percent of the campaign's average daily budget. Google's example: 5% of a $1,000 average daily budget keeps that channel "at or below $50 per day."
• A 0% cap works as an off switch: "If you set a Low priority channel's budget allocation to 0%, Google won't spend on that channel."

It applies to four campaign types. Search campaigns can rank Google Search, search partners and the Display Network. Shopping can rank Google Search and search partners. Performance Max can rank "Google channels" (Google's label for YouTube, Gmail, Maps and the rest combined), search partners and the Display Network. Demand Gen gets prioritization but not the percent cap.

Start with the default. Google's help page says: "By default, all channels are set to High priority." Nothing changes in your account until someone goes in and changes it.

The cap is also soft. Google's announcement says its tools will aim to hold spend on those channels within the limit "on a best-effort basis." The help page is blunter: "this isn't a guarantee." Expect spend to land near the number you set.

What it means for your business

For most local businesses, search is where the buyers are. Someone typing "emergency dentist open Saturday" wants you today. A banner on a recipe site sometimes works, but often it is where budget goes when nobody is watching.

The side channels that took budget without asking now have a dial, and it only helps if someone turns it.

Now you can say "yes, but only a little." That helps if you suspect Display is wasting money but do not want to kill it blind.

Google spells out one catch. If a campaign is not limited by budget, ranking channels changes little. The help page says "Channel prioritization doesn't change how your budget is spent when your campaign isn't limited by budget," for Target CPA, Target ROAS and Target CPC bidding. The percent caps on Low priority channels still apply in that case.

Put February 2027 on your calendar, too. Google's help page says that "Starting in February 2027, all Search campaigns with Display Expansion enabled will automatically migrate" to the new controls. Display Expansion is the setting that lets a Search campaign also show on the Display Network. To keep things roughly as they are, Google suggests setting the Display Network to Low priority with a 50% allocation. Google's help page also says the Display Network will stop serving on Search campaigns that use Target Impression Share.

What to do this week

Nothing has to change this week. Someone should look, though, so that whatever the setting is, you chose it.

1. Check whether you have it yet

   In Google Ads, open Account settings and look for the "Channel Prioritization" card. If it is not there, the rollout has not reached you. Check again in a few weeks.

2. Find out where your money goes now

   Ask whoever runs your ads for a report of spend and results by network: Google Search, search partners and Display. You are looking for spend with few calls, bookings or form fills behind it.

3. Make a decision per campaign

   Keep Search High. If a side channel earns its keep, leave it High. If you are not sure, set it to Low with a small cap rather than switching it off.

4. Use 0% only on purpose

   Zero stops spend on that channel. That is right for a channel that has never produced a customer. It is the wrong move if nobody has looked at the numbers.

5. Put February 2027 on the calendar

   If any Search campaign has Display Expansion on, decide before then what you want Display to get. Google's suggested match for today's setup is Low priority at 50%.

If you run several locations with separate ad accounts, note one limit: Google says "You can't set channel prioritization from a manager account." Each account, or each campaign, has to be set on its own.

We wrote last week about another Google setting that starts on by default: Google can now put your website's deals into your ads.
