消息广告仅对提升转化量有效。

Incorrect. Message Ads are versatile and can be used for various objectives beyond just conversions. They are highly effective for driving engagement, building brand awareness, generating leads, and nurturing relationships with prospects by delivering personalized content directly to their LinkedIn inbox. While they can certainly contribute to conversions, limiting their utility to only that objective overlooks their broader strategic value in the marketing funnel. For instance, they can be used to invite users to events, share valuable resources, or initiate conversations, all of which support different stages of the customer journey.
