Google is experimenting with negative keyword lists for Performance Max campaigns, a feature long requested but previously unavailable for this campaign type. This allows advertisers to exclude specific keywords from triggering ads, offering more precise targeting and improved budget allocation. By filtering out irrelevant or low-performing search terms, marketers can potentially enhance return on investment and campaign relevance. This development reflects Google’s effort to balance automation with advertiser input, addressing concerns about efficiency and targeting accuracy.
Performance Max campaigns have traditionally relied on automation and machine learning to optimize ad delivery across multiple channels, limiting advertiser control over search queries. Introducing negative keyword lists provides a way to refine targeting by excluding keywords that do not align with business goals or generate low conversions. For example, a seller of premium products might block bargain-related keywords to reach a more qualified audience. This control can improve click-through and conversion rates by focusing ads on users more likely to engage.
Beyond budget efficiency, excluding certain search terms offers clearer insights into audience segments that respond best to messaging. This can inform marketing strategies and creative development, providing greater transparency in campaign performance. As noted by Search Engine Land’s Ginny Marvin, this test could reshape campaign optimization by allowing advertisers to filter out irrelevant or low-performing queries, blending automation with manual oversight.
Although Google’s official documentation states that negative keyword lists are not yet supported in Performance Max, some users have reported seeing this feature active in their accounts. Industry experts like Adriaan Dekker, Jeremy Young, and Alyssa Knab have highlighted this development, suggesting Google is testing ways to give advertisers more granular control over automated campaigns.
This feature addresses frustrations with limited targeting control, enabling marketers to prevent ads from showing on irrelevant or low-value queries. It can improve brand safety and budget efficiency by filtering out traffic that doesn’t align with campaign goals. However, it remains unclear whether this is a limited test, early rollout, or interface anomaly, as Google has not issued an official statement. Advertisers are advised to monitor and experiment cautiously.
How will negative keywords affect automation?
Negative keywords allow marketers to inject human judgment by preventing ads from appearing on unwanted search queries without overriding Google’s machine learning. This fine-tunes targeting and reduces wasted spend while maintaining algorithmic efficiencies.
Is this feature widely available?
Currently, it is in testing and not confirmed for full rollout. Some users have access, but Google has not announced a standard release. Advertisers should treat it as experimental and observe its impact before making major changes.
What are the practical benefits?
Excluding low-engagement or irrelevant search terms improves traffic quality and aligns ad spend with business objectives. For instance, blocking discount-related keywords helps target premium customers, potentially increasing click-through and conversion rates.
How does this affect reporting and insights?
Negative keyword lists provide clearer visibility into which search terms drive meaningful results, aiding message refinement and campaign analysis. This adds a layer of control that complements automated decision-making.
Google’s testing of negative keyword lists marks a step toward greater advertiser control over automated targeting. By excluding irrelevant or low-performing keywords, marketers can improve budget efficiency, campaign relevance, and audience insights. While still experimental, this feature could transform Performance Max into a more flexible and strategic tool aligned with specific business goals.
As Ginny Marvin from Search Engine Land noted, “this test could reshape campaign optimization by allowing advertisers to filter out irrelevant or low-performing queries, blending automation with manual oversight.”
