If your marketing objective is to build awareness, what audience solutions should you consider using in your Google video campaign?

The selection is correct because Affinity audiences and custom audiences are the primary solutions for driving broad reach and establishing a brand's presence among relevant users at the top of the marketing funnel. While Affinity audiences allow you to reach massive groups of people based on their long-term interests and lifestyle habits (like "Auto Enthusiasts" or "Gamers"), custom audiences provide the flexibility to build your own niche segments by grouping together specific keywords, URLs, and apps related to your industry. In an awareness-driven campaign, these two solutions work in tandem to ensure your video is seen by a large, yet qualified, audience that hasn't necessarily entered a specific "buying" phase yet, but whose general behavior aligns perfectly with your brand's identity. This approach prioritizes efficient cost-per-thousand (CPM) bidding and high-volume impressions, which are the fundamental metrics for measuring successful brand lift and top-of-mind awareness.
