您在一家运动服饰公司工作，该公司将推出一个新的运动鞋系列。您想要使用 Google 受众群体功能向用户投放广告，但不希望您的定位条件限制广告效果。 为了确保覆盖恰当的受众群体，您应在 Display & Video 360 中实施哪种定位方式？

Optimized targeting is the correct choice because it uses Google's AI to find new and relevant audiences beyond your manually selected segments, helping to expand reach while maintaining relevance. This prevents your initial targeting criteria from being overly restrictive, which is a key concern for the sports apparel company. Demographic targeting is too broad on its own and wouldn't ensure reaching the right audience for a new sneaker line without additional layers. Viewability targeting focuses on ad delivery quality, not audience selection. Device targeting restricts where ads appear, but doesn't help identify the most relevant users for the new product.
