您的客户最近推出了一个新的自行车系列，并专门针对斜梁款车型制作了一个广告。 您应使用什么类型的受众群体来确保向希望购买这种自行车的用户展示该广告？

Custom intent audiences are ideal for reaching users actively researching or planning to purchase specific products or services. In this scenario, the client wants to target users interested in buying a specific bicycle model, making custom intent the most precise option. This audience type allows you to define keywords and URLs that users are actively searching for or visiting, indicating strong purchase intent. Lifestyle audiences are too broad, targeting general interests rather than specific purchase intent. Target audiences are a general term and don't specify the intent level needed here. Custom affinity audiences are for reaching users based on their long-term interests and passions, which is less precise than purchase intent for a specific product.
