Asset Group Signals

What Are Asset Group Signals?

Weak or overly broad signals force the PMax algorithm into a long learning phase with high wasted spend. Use your best customer lists as a signal so Google can find similar users. Create separate Asset Groups for different product categories and assign each with specific Custom Segments, remarketing lists, or interest profiles. Check the Insights tab regularly to see which audiences the campaign is actually reaching.

Asset Group Signals are audience signals you assign to an Asset Group in Performance Max. They don’t serve as hard targeting, but as a hint for Google’s algorithm about which user groups are particularly relevant for this Asset Group. Google uses these signals as a starting point and expands the audience independently to find similar users.

You can use various signal types: Custom Segments (based on search terms or URLs), first-party data (remarketing lists, Customer Match lists), interests and detailed demographics, and combined segments. The more precise and high-quality your signals are, the faster the algorithm finds the right users. Weak or overly broad signals lead to a longer learning phase and wasted spend.

In practice, use Asset Group Signals strategically. Create separate Asset Groups for different product categories or customer groups and assign specific signals to each. Use your best customer lists as a signal so Google can find similar users. Add Search Themes for the search component of PMax. Monitor in the Insights tab which audiences the campaign is actually reaching, and adjust your signals based on results.
