For years, Google told you to trust the blend. Search, partners, Display, all in one pot, and the algorithm decides. Now Google is handing you a dial. If you don't touch it, you're telling Google the old blend was fine. For a lot of accounts, it wasn't.
What changed
On October 14, 2026, Google announced channel prioritization and budget allocation, with rollout starting October 15. Per Google's help page, here's how it works:
- You set each channel to High or Low priority. Everything starts at High, so nothing changes until you act.
- High-priority channels spend first. Low-priority channels get what's left.
- For Low-priority channels, you can set a budget allocation: a daily percentage cap based on the campaign's average daily budget. Set it to 0% and that channel stops spending.
- Caps are a target, not a guarantee. Spend can occasionally go over. Allocations reset daily and nothing carries over.
What you can rank depends on campaign type:
- Search: Google Search, search partners, Display Network
- Shopping: Google Search, search partners
- Performance Max: Google channels (bundled), search partners, Display Network
- Demand Gen: Google channels and Display Network, priority only, no budget allocation
Some limits: you can't set this from a manager account, shared budgets need campaigns of the same type, and API and Editor support is still "coming later." The rollout is gradual, so you might not see it yet.
The part that'll catch people out: from February 2027, Search campaigns with Display Expansion move to these controls automatically. Google says the current spend setup goes away, and to keep roughly the same behavior you should set the Display Network to Low priority with a 50% allocation. Display will also stop serving on Search campaigns using Target Impression Share.
PPC Land's write-up adds that Google's Ginny Marvin confirmed on October 16 that PMax advertisers can set search partner spend to 0%.
Why this matters for your money
How bidding reacts depends on your strategy, and this is where people will misread the feature.
If you run Target CPA, Target ROAS or Target CPC and you're not budget-limited, prioritization alone mostly won't change spend. The allocation caps still apply, though.
If you're budget-limited on tCPA or tROAS, High-priority channels spend first within your target, and leftovers only flow down if the target can still be hit.
On Maximize Conversions, Maximize Conversion Value, Manual CPC and similar, High-priority channels get the budget first and the rest trickles down.
So the money question is simple. Which channels actually produce customers for you? In our experience, search partners and Display inside Search campaigns are where lead quality often drifts for local service businesses. Junk form fills, accidental clicks, calls that hang up. You can't fix that with a bid. You can now fix it with a cap.
Your setup plan for this week
- Pull a network segment report. In your campaigns view, segment by network for the last 90 days. Look at cost, conversions and, if you import offline data, qualified leads or revenue for Google Search vs. search partners vs. Display.
- Score each channel honestly. If a channel's CPA is far worse than Google Search, or its leads rarely close, mark it as Low priority.
- Start with a cap, not a zero. Unless the channel is clearly burning money, set something like 5 to 10% first. Google's own example is 5% of a $1,000 daily budget, aiming for about $50 a day. Watch two to four weeks of results before cutting harder.
- Go to 0% when the data is clear. If partners or Display have spent real money with nothing to show, turn them off. Don't keep paying for hope.
- Prep for February 2027 now. List every Search campaign with Display Expansion on. Decide whether you even want Display there. If you do, set Low priority at 50% to mirror today. If you don't, set it to 0% and stop worrying about the migration.
- Configure client accounts one at a time. Agencies, take note: there's no manager-account shortcut. Put it on your checklist for every account.
- Annotate the change date. Your blended CPA will move. You want to know why.
Our take
This is one of the few 2026 updates that gives control back instead of taking it away. That's worth saying, because most of this year's news has been "on by default, opt out if you can find the switch."
We'd still be careful with PMax. Bundled "Google channels" means you can't separate YouTube from Gmail from Discover, so the control is partial. And "best-effort" caps mean you should check actual spend by network every couple of weeks, at least at first.
But for lead gen accounts that have been quietly paying for partner and Display traffic that never converts into revenue, this is the cleanest fix Google has offered in years.
Takeaway: Rank your channels by real business results, cap the weak ones, and handle Display Expansion before Google migrates it for you in February.
