Google Ads lets advertisers choose which networks get their budget first

Google announced it on October 14, 2026, in a post on the company's blog signed by Tal Akabas, Director of Product Management, Google Ads. The post introduces two optional controls, channel prioritization and budget allocation, rolling out globally across Search, Shopping, Performance Max and Demand Gen campaigns. It matters for anyone who pays for Google ads, because the choice on networks like Search partners and the Google Display Network has mostly been on or off. Now there is a middle setting, and one existing setting is going away.

Google Ads now lets you rank where your budget goes first

Channel prioritization lets an advertiser label each channel "High priority" or "Low priority". According to Google's blog post, campaigns will fully fund high-priority channels, within their target when using Target CPA or Target ROAS, before giving any remaining budget to lower-priority ones. On a Search campaign, that means you can put Google Search in the top tier and Search partners or the Google Display Network below it.

Google's help page says every channel is set to High priority by default, so nothing shifts until you change it yourself. Search Engine Journal, which received an early demonstration during a virtual roundtable with Google's product team, reported the same thing: advertisers have to change the settings themselves if they want some channels to get less.

Settings can be made once at the account level for each campaign type, then overridden for a single campaign or a shared budget. Google's help page walks through it: open Account settings, find the "Channel Prioritization" card, pick the campaign type, assign the tiers and save. One limit matters for owners who let an agency run their ads: the help page says channel prioritization cannot be set from a manager account, only directly in each client account or at campaign level.

The spending cap is a percentage, and Google calls it best effort

The second control, budget allocation, applies only to Low priority channels. You enter a percentage, and Google aims to keep daily spend on that channel under it. The help page gives its own example: a 5% allocation on a $1,000 average daily budget means Google AI will aim to keep spend on that channel at or below $50 per day. The percentage is of the campaign's average daily budget, not of what the campaign actually spends, and it resets each day with no carryover of unspent or overspent amounts.

The cap is not a hard limit: Google's help page says it works on a best-effort basis and that daily spend on that channel may occasionally exceed it. Search Engine Journal made the same point, telling advertisers not to assume the percentages are hard caps. Setting 0% is allowed, and the help page says Google then won't spend on that channel, which Search Engine Journal noted also works inside Performance Max.

Think of it like a household budget where the bills are paid first and a side project gets what is left, but never more than an agreed share of the monthly budget. Prioritization decides the order. The percentage decides the ceiling.

There is a catch in how the two interact. Google's blog says that for Target CPA or Target ROAS campaigns that are not limited by budget, prioritization alone will generally have no impact, because the system tries to hit your target across all channels. In those campaigns, only the percentage limit changes anything. Google aims this at advertisers who switched networks off: its blog says those who historically opted out of Search partners and the Display Network can use the new lever to test them "with more confidence and clearer limits."

February 2027 changes Search campaigns that also show on Display

This is the part with a deadline. Starting in February 2027, Google says the current spend allocation setup for Search campaigns with the Google Display Network turned on will go away, and advertisers may see a shift in channel spending. Today, Search Engine Journal explains, Google already favours Search inventory over Display behind the scenes when both are enabled. Because the new system starts every channel at High priority, that preference disappears unless you recreate it.

To keep things as they are, Google's blog and help page both say to set the Google Display Network to "Low priority" with a 50% budget allocation. Search Engine Journal reported that Google's product team confirmed a one-click migration option when the controls launch. The help page adds two details few will notice. If you set channel priorities on a Search campaign before February 2027, the new settings apply right away and replace the old Display behaviour. And as part of the change, the Display Network will no longer serve on Search campaigns that use the Target Impression Share bid strategy.

Which campaigns get which switches, and what is still missing

The help page says the controls start becoming available progressively on October 15, 2026. Search campaigns get Google Search, search partners and the Google Display Network. Shopping gets Google Search and Google search partners. Performance Max gets Google channels, Google search partners and the Display Network. Demand Gen gets Google channels and the Display Network, but budget allocation is not supported there, and Search Engine Journal reported that limited Demand Gen feature testing is expected to begin in November.

In Performance Max and Demand Gen, Google groups Search, YouTube, Maps, Gmail and Discover together as "Google channels." A business that wants to spend less on YouTube inside Performance Max cannot do it with this control, because those Google-owned placements cannot be prioritised individually. Google's help page points advertisers who want that kind of control to separate Search and Demand Gen campaigns. Search Engine Journal also reported that Google is running a small alpha experiment with more advanced Performance Max channel controls alongside this.

The other side: several things are unclear or unfinished. Google has not given a date for when each account gets the controls; the help page says availability "may vary depending on campaign type and rollout timing." The sources disagree on the API: Search Engine Journal reported Google confirmed API support at launch, while Google's help page says support for the Google Ads API and Google Ads Editor is "coming soon." Reporting trails the controls, with Search Engine Journal saying expanded channel reporting for Search is expected in the first quarter of 2027, so for now you judge network performance with existing segmentation. Campaign total budgets work with prioritization only for Demand Gen. And Search Engine Journal raised a fair worry: if a campaign already meets its CPA or ROAS target, pushing inventory into a low tier could reduce the opportunities the bidding system has to work with.

Two other Google Ads changes this week ask for more data

Barry Schwartz of Search Engine Roundtable, who wrote that he saw an alpha release of these controls back in August, reported two related changes. On October 13, he reported that Google rebuilt its Data Strength Best Practices help document into a detailed guide that pushes first-party data, Data Manager and AI-powered campaigns. Google's own page now includes figures such as a 14% average uplift in observed conversions for customers who upgrade to Google tag gateway, a number that comes from Google's internal data.

On October 14, Schwartz reported that Google appears to be testing a Search terms and ad combinations report, spotted by Natasha Kaurra, who posted a screenshot on LinkedIn. She said it shows search terms next to the headlines, descriptions and landing pages that appeared with them, and called it "another way to identify mismatches between search intent, ad messaging, and landing pages." It is a test, not a rollout.

The pattern is consistent. Search Engine Journal reported that Google's product team described the goal as giving advertisers more control over spending while still letting automation optimize toward campaign goals. The automation stays in charge; the owner gets a few more dials around it.

Bottom line

For most owners, nothing happens today, because every channel starts at High priority. The real decisions are two. If your Search campaigns show on the Display Network, check them before February 2027, or your spending mix may change without you touching anything. And if you once switched off Search partners or Display because the traffic looked poor, you now have a way to try them again with a ceiling instead of an open tap, keeping in mind that Google calls that ceiling best effort. Do you know whether your Search campaigns have the Display Network turned on right now?
