广告主如何运用从转化提升测试中了解到的信息？请选择 3 个选项。

Advertisers use insights from conversion lift tests to optimize their campaigns effectively. Optimizing audience targeting based on statistically significant segments allows advertisers to focus on groups most likely to convert, improving ROI. Proving the impact of brand and awareness campaigns on downstream conversions helps justify investments in upper-funnel activities by demonstrating their contribution to overall business goals. Reallocating budget to campaigns driving the most conversions ensures resources are directed towards the most efficient and effective strategies, maximizing conversion volume. Identifying campaigns that resonate long-term is a broader goal that conversion lift tests can contribute to, but it's not a direct, immediate application of the test results in the same way as the other options.
