Martin 正在查看他的品牌提升测试结果。他想确认自己关注的是与目标客户感知相关的指标，而不是直接的表现指标。Martin 可以通过品牌提升测试衡量以下哪两项指标？请选择两项

Martin is looking for metrics related to customer perception, which brand lift studies are designed to measure. Product consideration and brand familiarity are both key indicators of how customers perceive a brand and its offerings, reflecting changes in their attitudes and awareness. Brand lift studies directly assess these types of perceptual shifts. Conversion rate and sales revenue are direct performance metrics, indicating immediate actions or financial outcomes, not perceptions. While a successful brand lift can indirectly lead to improved conversions and sales, these are not the primary metrics measured by a brand lift study itself. Ad engagement rate is also a performance metric, measuring interaction with an ad, not a change in brand perception.
