Control These Performance Max Settings

▼ Summary
– Performance Max campaigns have evolved from being opaque to becoming a critical tool, with Google steadily adding more functionality and reporting visibility.
– Advertisers can now directly add campaign-level negative keywords using a search terms report, a significant improvement over the previous cumbersome manual process.
– Placement reports, though limited to impression-level data, allow for optimization by excluding unsuitable placements like kids’ programming or specific mobile apps at the account level.
– Campaign efficiency can be improved by using ad schedules to restrict ads during off-peak hours and by applying demographic or device-level exclusions found in the campaign settings.
– While AI-generated image assets are improving, high-quality AI video content is not yet reliable, and overall network control remains limited compared to other campaign types.
Google’s Performance Max has transformed from an opaque system into a vital campaign format for modern advertisers. Each quarter brings new features and enhanced transparency, giving marketers more actionable control over their campaigns. While you cannot dictate every aspect, several specific settings now allow for meaningful optimization and performance improvements. Focusing on these controllable elements is key to driving better results.
A major advancement over the past year is the introduction of campaign-level negative keywords. Previously, adding negatives required a cumbersome process of submitting spreadsheets to Google for implementation. Now, with the integrated search terms report, advertisers can directly select irrelevant queries and add them to a negative list with the same ease as in Search or Shopping campaigns. This provides direct control over where your ads appear in search results.
Similarly, the placements report offers valuable optimization opportunities. Google has relocated this data to the “Where ads showed” section at the campaign level, simplifying access. Although reporting remains at the impression level, it reveals where your ads are displayed across the network. Marketers can use this insight to add underperforming or irrelevant sites and apps as account-level negative placements. This is configured in Tools under Content suitability and Advanced settings. Reviewing this report can uncover placements in unsuitable contexts, like children’s programming, or highlight an over-reliance on mobile apps.
For budget efficiency, leverage the ad schedule controls found in the same campaign reporting section. Google defaults to an open schedule, but for advertisers with limited budgets, restricting ads during off-peak or low-converting hours is a powerful tactic. You can set a campaign-level ad schedule by navigating to Campaigns, then Audiences, keywords, and content. This simple adjustment helps concentrate spend on the most valuable time periods.
Refining your audience is another area of growing control. Demographic exclusions are now available at the campaign settings level. This is particularly useful if you know certain age groups or genders are not part of your target market. Adjustments are made under Campaign settings and Other settings. While reporting on demographic performance within PMax remains limited, this feature allows for strategic exclusion based on your business knowledge.
Device-level targeting has also become a controllable factor. Initially lacking even basic reporting, Performance Max now allows you to opt out of specific devices. It’s wise to periodically review performance segmented by device at the campaign or asset group level. This data helps determine which devices best drive your goals. You can then adjust targeting in Campaign settings under Other settings, either restricting poor performers or testing new devices to gauge their impact.
The quality of your ad assets significantly influences performance on display, YouTube, and Discover networks. A common challenge is producing enough high-quality images and videos. AI-generated assets are rapidly evolving to help fill this gap, enabling more effective targeting across these visual channels. Google already offers AI-generated image assets from product feeds that are quite impressive. While AI video generation still has room for improvement, it represents a growing tool for scalable creative production.
It’s important to recognize the current limits of control. The channel controls report, for instance, shows where ads are serving but offers few direct levers to change performance within the campaign itself. For now, influencing volume across networks relies on adjusting creative inputs and bids. To completely opt out of certain networks and focus solely on shopping, a feed-only Performance Max campaign is the appropriate solution. Future updates will likely bring more granular channel controls, similar to those in Demand Gen campaigns.
Performance Max is no longer a black box. With strategic use of negative keywords, placement exclusions, ad scheduling, and audience refinements, advertisers can move beyond a passive approach. By actively managing these levers, you can run Performance Max campaigns with greater precision, efficiency, and confidence.
