Giselle 供职于一个新品牌，该品牌具有远大的增长目标。她在创建其首个品牌认知度推广活动时，应考虑哪些策略？请选择所有适用选项。

For a new brand with ambitious growth targets, building brand awareness requires broad reach and diverse engagement. Using multiple ad formats (e.g., video, image, carousel) increases the likelihood of capturing attention across different user preferences and platforms, enhancing memorability and recall. Targeting a broad audience is crucial for initial brand awareness campaigns because the goal is to introduce the brand to as many potential customers as possible, establishing a foundation before refining targeting for conversion. Starting with single-image ads or a single target audience would be too restrictive for a brand aiming for significant growth, limiting early exposure and impact.
