This article records an earlier Performance Max brand-traffic problem in one client account. Treat that account experience as a reason to verify the controls and search terms, not proof that brand exclusions fail in every campaign. First define whether the aim is excluding brand queries or measuring incremental new-customer acquisition; those are different questions.

There’s an issue when it comes to the Search network and more specifically Brand Keywords. The Brand Exclusion feature within pMax settings should solve that, but it might not be as reliable as you think.
Real-World Insights into pMax’s Brand Exclusion Efficacy
We explored using the Brand Exclusion feature in pMax settings for one of our client’s campaigns. Our primary goal was to discover if this tool could effectively prevent our ads from appearing during searches for brand-related keywords, thereby allowing us a sharper focus on non-branded terms.
To our surprise, Google representatives warned us that the Brand Exclusion feature might not solve the problem of showing our pMax ads when people search for brand-related keywords.
In the client account described here, 99% of reported pMax traffic came from brand-related keywords despite the selected exclusion. That historical observation does not establish how the feature works in another account. Check the brand list, variants, selected campaign and reporting period before attributing an unexpected result to the control itself.
Seeking Solutions: Direct and Manual Keyword Exclusion
Start with the account’s brand list and confirm it is applied to the intended campaign. Google’s brand-settings guidance says Performance Max brand exclusions apply to Search and Shopping inventory. Include genuinely distinct brand names where relevant, then review the resulting queries and business outcomes. If the saved setup and observed delivery disagree, raise that specific evidence with support.
The big lesson here is that the Brand Exclusion feature isn’t foolproof. Relying solely on it could still get your pMax ads mixed up with brand-related keywords, which isn’t great for your campaign if you want to target new users.
Document the saved setting and the period in which it was active before evaluating the result. Excluding brand traffic can change reported conversion volume, and it does not by itself prove that the remaining conversions are incremental.
Maintaining and Analyzing Campaign Performance
Remember, even with manual exclusions in place, a successful ad campaign depends on keeping an eye on how it’s doing. Regularly check your campaign’s performance and check the Search Terms report inside the Insights tab. This will show you what search terms are captured by your pMax campaign and if you are reaching the right audience with the Search network.
Summarizing
The Brand Exclusion feature in pMax settings isn’t the magic solution. Our experience showed that, even when it’s turned on, brand-related keywords can still dominate your pMax campaign.
Check controls, query evidence and downstream customer quality together. A support escalation is useful when you can show a reproducible mismatch, but it is not a substitute for measurement. Use a comparable reporting period and a separate incrementality test when the question is whether pMax adds customers the business would not otherwise have acquired.
