Google Ads Performance Max campaigns may filter out navigational or brand-specific search queries, Search Engine Roundtable reported on November 3. Google updated its help document on how Performance Max interacts with other campaigns in an account, adding a new section on that filtering. For advertisers who run both Performance Max and dedicated brand search campaigns, the detail matters, because it affects which campaign actually serves a query for their own name.
Performance Max is Google's campaign type that serves ads across Search, YouTube, Display, Discover, Gmail, and Maps from a single campaign, using automation to find conversions. Its interaction with other campaigns has always been a source of questions, because advertisers worry that an automated campaign will compete with, or cannibalise, their carefully controlled brand campaigns. The updated help text addresses that worry directly by describing how navigational and brand queries are handled.
The key point is filtering, not exclusion in the absolute sense. Performance Max may hand certain brand and navigational queries back to dedicated Search campaigns, rather than serving them itself. That is a meaningful clarification for account structure. It means an advertiser does not necessarily need to fight Performance Max for its own brand terms, and it gives a documented basis for deciding when a separate brand campaign is doing the work and when Performance Max is filling gaps.
Brand queries are the highest-intent, cheapest, and most defensible traffic an advertiser owns. A user searching for a company by name is already close to converting, and the cost of losing that query to a competitor, or to an inefficient campaign, is high. If Performance Max served those queries indiscriminately, it could inflate brand costs, obscure performance, and make it hard to tell whether the automated campaign was creating demand or merely harvesting it. Filtering brand queries out protects the measurement as much as the spend.
The same logic applies to navigational queries, where a user is trying to reach a specific site rather than discover options. Serving a generic automated ad to a user who already knows where they want to go is wasteful, and it can create a poor experience. A system that recognises navigational intent and routes it appropriately is doing the advertiser a favour, even if the advertiser never sees the routing happen. The help update makes that routing visible, which is what advertisers need to trust it.
Advertisers should review their account structure in light of the update. If you run a dedicated brand Search campaign alongside Performance Max, check whether brand queries are being served by the campaign you intend, and whether Performance Max performance changes when brand traffic is filtered. If you do not run a brand campaign, understand that Performance Max may still serve brand queries in some circumstances, and consider whether a dedicated campaign would give you cleaner control and measurement.
SEOs should note the interaction with organic brand results. A brand query is also the query where a company's own site, knowledge panel, and now possibly a right-column AI Overview all compete for attention. Paid filtering does not change the organic picture, but it does change the total brand SERP. When reporting brand visibility, look at paid and organic together, and do not assume a change in one channel explains a change in the other.
The help text is a description, not a guarantee for every query, and advertisers should test it in their own accounts. Watch for brand query impressions in Performance Max reports, compare them with brand Search campaign performance, and note any shifts after the documentation change. If brand traffic moves between campaigns, the cause may be the filtering described here, a change in auction dynamics, or a change in user behaviour, and only account-level data can separate those.
The wider trend is toward more documented automation boundaries. Google has been adding controls and explanations for Performance Max over time, because advertisers will not hand over budget to a system they cannot understand. Each clarification like this one makes the automated campaign slightly less of a black box, and slightly easier to combine with the controlled campaigns that still matter for brand.
