Performance Max Brand Exclusions vs. Negative Keywords

Performance Max brand exclusions and negative keywords are both used to limit unwanted search traffic, but they work at different levels. Brand exclusions are designed to prevent selected brand searches from matching eligible Performance Max search and Shopping inventory. Negative keywords exclude specific search terms according to their match rules and campaign support.

What brand exclusions are for

A brand exclusion lets a team identify brands whose search queries should not be served by a Performance Max campaign. This can help separate branded demand from non-brand acquisition or prevent a campaign from taking credit for searches the company wants measured elsewhere.

The brand list is broader than a single literal keyword, so review how the platform interprets brand names and variants. Exclusions affect the campaign where they are applied and may not control every type of inventory or placement.

• Use brand exclusions when the intent is to remove a brand-query category.
• Review spelling, related names, and product-brand relationships.
• Check the campaign’s eligible inventory and current settings.

What negative keywords are for

Negative keywords block specific words or phrases from triggering ads. Their match behavior differs from positive keywords and should be checked before broad account-level application. They are useful for excluding clear themes such as jobs, support requests, or unrelated products when those searches do not fit the campaign objective.

A negative keyword can remove useful queries if it is too broad. Search-term reviews should preserve relevant research and comparison intent where those searches matter to the business.

• Use negatives for explicit query-level exclusions.
• Check match type and campaign scope before applying them.
• Review conflicts with active keywords and high-value search terms.

Choose the control that matches the goal

Choose a brand exclusion for a brand-level separation decision and a negative keyword for a specific query or theme. They can be used together, but each setting should have an owner and documented purpose. Measure non-brand performance with a clear definition and avoid interpreting a change in reported branded traffic as incremental growth.

After applying exclusions, monitor search terms, conversion quality, and spend distribution. A setting may reduce one source of traffic while causing the campaign to use its budget elsewhere; review the overall mix rather than one metric alone.

For example, a brand exclusion may be appropriate when a PMax campaign is intended to find new customers and brand searches are reported separately. A negative keyword such as “careers” may instead remove a specific irrelevant query theme. The distinction should be written down in the campaign’s measurement plan.
