无需公司主页，就可以设置领英广告推广活动。

This statement is incorrect. To run advertising campaigns on LinkedIn, a company page is a mandatory requirement. Your LinkedIn Ads are linked to your company page, which serves as the landing point for users who click on your ads and provides essential brand information and credibility. Without a company page, the platform cannot attribute the ads to a specific entity, nor can it provide a destination for ad clicks. Therefore, setting up a company page is a foundational step before launching any LinkedIn advertising efforts.
