品牌提升测试可以衡量以下哪些指标？请选择三项

Brand lift tests are designed to measure the impact of advertising campaigns on brand-related metrics, directly assessing how a campaign influences consumer perceptions and attitudes. Brand perception, affinity, and engagement are key indicators that reflect these changes. Brand perception measures how consumers view the brand, affinity gauges their emotional connection, and engagement reflects their interaction and interest. Click-through rate (CTR) and bounce rate are website-centric metrics that measure immediate user behavior on a digital platform, not the broader, attitudinal shifts that brand lift tests aim to capture. While CTR and bounce rate can be influenced by brand awareness, they are not direct measures of brand lift themselves.
