Can you target all the LinkedIn members that work in a certain company?

Targeting LinkedIn members based on their company is indeed possible, but there is an important condition attached: you can only target members from a specific company if that company has at least 300 employees. This requirement helps ensure that the target audience is substantial enough for advertisers to run effective campaigns and gain meaningful insights into engagement.

When the company has 300 or more employees, it allows for more precise segmentation and connection opportunities, making the advertising efforts more effective. This means that if a company has fewer than 300 employees, LinkedIn restricts the capability to ensure privacy and compliance, which is crucial in maintaining the integrity of the platform and protecting user data.

The other options do not align with LinkedIn's advertising policies or audience targeting capabilities. For instance, while targeting is not limited to just groups or job titles, it does have specific guidelines around company size that must be adhered to for successful targeted advertising.
