小洁正在投放一个 Google 应用广告系列，她知道虽然采用了机器学习技术，但她作为营销者提供的输入数据仍然非常重要。小洁可通过哪三种方式最有效地引导机器，从而取得满意的成果？（请选择三项。）

Google App Campaigns rely heavily on machine learning, but marketer input is crucial for success. Providing sufficient data and time allows the machine learning algorithms to learn and optimize effectively. Continuously refining the campaign strategy over time, based on performance insights, helps guide the system towards better outcomes. Smartly setting bids and budgets ensures the campaign operates within desired financial constraints while maximizing performance. Setting location targeting at the ad group level is a valid strategy but not one of the three most effective ways to guide the machine for overall satisfactory results. Daily bid adjustments are generally discouraged as they disrupt the machine learning's optimization process; it needs stability to learn.
