Google Ads Channel Prioritization: The New Budget Controls and the February 2027 Deadline
Google has given advertisers a way to tell it which channels to fund first, and how much of your daily budget the weaker ones can take. It is called channel prioritization, it is rolling out now, and if you run Search campaigns with the Display Network switched on, you have a deadline attached.
Search Engine Land reported the launch on 14 October 2026. Here is what it does, what is still unclear, and what we would do about it.
What Google Ads channel prioritization actually does
There are two controls, and they work as a pair.
Channel prioritization lets you mark each channel as High or Low priority. Google funds the High-priority channels first, then spills what is left into the Low-priority ones.
Budget allocation lets you set the maximum share of your daily budget that Low-priority channels can take. Google describes these limits as best-effort rather than a hard cap, so treat the percentage as a strong steer, not a guarantee.
The controls apply across four campaign types: Search, Shopping, Performance Max and Demand Gen. Which channels you can rank depends on the campaign. Search covers Google Search, Search partners and the Display Network. Shopping covers Google Search and Search partners. Performance Max and Demand Gen each have their own channel list.
Until now the only way to stop a campaign leaking budget into its weakest placements was to restructure the account or opt out of a network entirely. This is a dial instead of a switch.
The February 2027 deadline
This is the part to put in your diary. From February 2027, Google will remove the existing spend allocation setup for Search campaigns that have the Display Network enabled. If you want to keep your current behaviour, you set the Display Network to Low priority with a 50% budget allocation.
So if you run Search campaigns with Display ticked, you have a choice to make before then. Do nothing and the account moves to Google's new default behaviour. Make a deliberate setting and you stay in control. Doing nothing is the worst of those options, because you will not notice the change until the numbers move.
For the record, we have never liked Search campaigns with the Display Network ticked. Search intent and display browsing are different audiences with different conversion rates, and blending them in one budget makes both harder to read. If you are in that position, the cleanest answer is usually to separate them, not to tune the blend.
When this helps, and when it does not
It helps when one channel is clearly your best. If your Search campaigns convert on Google Search and the partner network brings in cheaper, lower-quality clicks, setting partners to Low with a small allocation caps the damage without losing the volume entirely. We covered the underlying problem in our post on whether to opt out of Search Partners.
It helps in Performance Max, where you have had the least control. Being able to say "fund Search and Shopping first, let the rest take scraps" is a real improvement on handing Google the whole budget and hoping.
It does not fix bad conversion tracking. If your account counts the wrong things as conversions, you will rank channels on bad data and fund the wrong one first. Fix measurement before you touch priority settings.
It does not replace Google's own optimisation. Google's Demand Gen documentation is clear that the system distributes budget to find the best-value conversions across channels, and advises judging the campaign on overall efficiency rather than channel by channel. A single channel can look cheap per conversion and still be too small to hit your target. Prioritisation is a guardrail, not a substitute for looking at total results.
What we would do this week
Do not rush into changing live campaigns because a new control exists. A sensible order looks like this:
- Audit where your spend goes today. Pull the network and channel split for every Search, Shopping, Performance Max and Demand Gen campaign over the last 90 days. Most accounts have never looked.
- Find the Search campaigns with Display ticked. These are the ones with the February deadline. List them.
- Decide per campaign, not per account. A lead-generation campaign and an ecommerce campaign will want different settings.
- Change one campaign at a time. Give each change enough time to show up in conversion data before judging it. Changing five at once tells you nothing.
- Write down what you set. When the budget allocation is a best-effort limit, you need a record of your intent to compare against what actually happened.
The controls are still rolling out globally over the coming months, so you may not see them in your account yet. Check the campaign settings periodically rather than waiting for an email.
Our view
This is a good change. Handing advertisers a way to say where money goes first is overdue, and the February deadline will force a decision that many accounts have been avoiding. The risk is that people treat a new setting as a strategy. It is not. It only works when the measurement underneath it is sound and you have already decided which channel earns its budget.
If you are not sure which of your channels is carrying the account, or what the February change does to your Search campaigns, that is exactly what our Google Ads management is built to sort out. Get in touch and we will review your channel split before the deadline, not after it.
