To understand the extent to which your Google Video campaign with a consideration goal is influencing viewer perception or intent for your product, you should use Brand Lift. Brand Lift is a free tool that measures the effectiveness of your video ads by focusing on metrics such as ad recall, brand awareness, and consideration, rather than traditional metrics like clicks, impressions, or views. This can help you align your campaigns with your marketing goals and provide detailed insights into the influence your campaigns have on viewer perception and intent. Brand Lift is available for in-stream and bumper ads bought via auction, but not for outstream and in-feed video ads.
