根据领英建议，使用领英广告的第一步是什么？

Setting up a Company Page is the foundational first step for advertising on LinkedIn. Your Company Page serves as the central hub for your brand's presence, providing essential information about your business, products, and services. All LinkedIn ads link back to your Company Page, allowing users to learn more about your organization. Without a Company Page, you cannot create or run ad campaigns. Publishing updates to your network is a content strategy, not an advertising prerequisite. Creating your first ad campaign is the second step, which follows the establishment of your Company Page.
