To advertise on LinkedIn, you’ll need to create an LinkedIn Ads account in Campaign Manager. An ad account allows you to create and manage advertising campaigns, view performance reports, and manage account assets such as Matched Audiences or conversion tracking.
You can manage the billing for each of your ad accounts separately. Depending on the size and scale of your advertising needs, you may need to create multiple ad accounts. Examples of when you may need multiple ad accounts include:
When you create an ad account, you’ll automatically be granted account manager and billing admin access. As an account manager or billing admin, you can add your colleagues or partners to the ad account as well.
