Question: For a new awareness Google Video campaign that uses custom audiences, you're considering overlaying Demographics and Detailed Demographics with Custom Audiences. Why should you keep the two audience solutions separate?
- In order to make sure the reach of the campaign won't become restricted.
- In order to prevent the average cost-per-view from increasing.
- In order to make sure there’s no limit on the types of video formats served.
- In order to avoid having the campaign not run at all.
Explanation
Demographic targeting and Detailed Demographics are narrowing controls in Google Ads, so adding them on top of Custom Audiences reduces the pool of eligible viewers. For an awareness setup, broader delivery is important because the goal is to maximize exposure rather than tightly filter reach. Google’s Video campaign guidance specifically notes that narrow audience targeting can restrict reach. Keeping these audience solutions separate helps preserve scale while still allowing each signal set to be evaluated on its own. Google Help+2Google Help+2
Why the other options are incorrect
Higher CPV Narrowing audiences can affect volume, but the key reason to separate these settings is preserving reach, not controlling CPV. Google Help+1
Format limits Audience layering does not exist to remove video ad formats; it affects who is eligible to see the ads. Google Help+1
Campaign won’t run Overlapping audience solutions may reduce delivery, but Google’s guidance describes the main issue as restricted reach rather than automatic non-delivery. Google Help+1
