An account manager at a media agency is creating a new awareness Google Video campaign that uses custom audiences. They're considering overlaying Demographics and Detailed Demographics with Custom Audiences in the new campaign. Why should they keep the two audience solutions separate?

Combining Demographics and Detailed Demographics with Custom Audiences can narrow the eligible audience too much. Awareness Video campaigns need enough reach to expose the message broadly across relevant users. Keeping these audience solutions separate helps avoid unnecessary audience restriction while still allowing each signal to be evaluated. This supports scale, which is central to brand awareness and reach .
