The Maze: Google is giving advertisers new ways to steer where their campaign budgets go. Announced on October 14, the controls are rolling out globally over several months. Businesses can rank eligible advertising channels and set spending targets for lower-priority inventory. Those percentage limits are softer than they sound.

The Details:
Two settings do different jobs. Channel priority tells Google which eligible inventory to fund first. Advertisers mark channels High or Low priority. Search partners are non-Google search sites and apps carrying Google ads; the Display Network supplies space on third-party websites and apps. A Search campaign can rank those networks separately from Google Search. Priority works within the campaign’s bidding goals. If a campaign targeting a cost per customer action or a return on advertising spend has enough budget, priority alone generally does little. The separate percentage allocation still applies. Choosing who gets served first matters less when everyone can already be served.
The denominator matters. A low-priority channel can receive a best-effort allocation based on the campaign’s average daily budget, rather than its actual spending. For an illustrative US$1,000 average daily budget, a 5% allocation means a US$50 daily target for that channel. It is not a promise that the channel will receive exactly 5% of the eventual bill. Spending may exceed the target. The allocation resets each day, without carrying unused or excess amounts forward. For a shared budget, the percentage applies to the entire pool across linked campaigns of the same type. Demand Gen, Google’s visual advertising campaign type, supports priority but excludes percentage allocations in the documented rules.
Campaign structure still limits choice. Performance Max, Google’s automated campaign spanning multiple advertising surfaces, keeps its own properties grouped as “Google channels.” Advertisers cannot lower YouTube’s priority separately from Search through this setting. Campaigns using a fixed total budget also face an exclusion: the new priorities apply only to Demand Gen in that configuration. Agencies must configure priorities inside client accounts or campaigns, rather than their manager account. Account defaults can be overridden at campaign level. These distinctions make an account-wide policy more complicated than choosing one percentage and walking away.
MarketMaze Take: Google is offering a narrower experiment, with a clear commercial motive: encourage advertisers who disabled partner networks to test them again. That can be useful. But the announcement establishes a new spending preference, not better sales, lower costs or a guaranteed financial boundary.
The deadline is a separate decision. In February 2027, Search campaigns with Display enabled lose their existing spending-allocation setup and may see money shift between networks. Google recommends Low priority and a 50% Display allocation to preserve the current configuration. Adopting priorities earlier replaces the old behavior immediately. Across markets, doing nothing and accepting a future default are two different budget decisions.
Visibility is ahead of control. Google announced broad Performance Max channel reporting in November 2025. Seeing a channel’s results still does not mean being able to rank every Google property separately. Restricting a campaign already meeting its goals can also remove useful opportunities. The test is whether a changed allocation improves the advertiser’s outcomes; neither the new setting nor Google’s rationale supplies that result.
