Can you use Klaviyo quiz data to improve ad targeting?

Yes. Klaviyo segments built from quiz data can be synced to Facebook, Instagram, and Google Ads as custom audiences. This means you can target ads specifically to people who indicated certain preferences, needs, or product interests in your quiz. Even more powerful, you can build lookalike audiences based on your best-converting quiz segments — for example, creating a lookalike of everyone whose quiz answers led to your highest-AOV product recommendation. You can also use quiz segments for exclusion targeting, making sure you're not showing irrelevant product ads to people who've already told you exactly what they want. This turns your quiz into a first-party data engine that makes your paid acquisition more efficient and reduces wasted ad spend.
