Which targeting option is available for LinkedIn users?

The correct answer is Company Size, as it is a specific targeting option available for LinkedIn users. LinkedIn's advertising platform allows marketers to target audiences based on various professional criteria, including the size of the company where a user is employed. This enables precise marketing to businesses of different scales, from small startups to large enterprises. By focusing on company size, advertisers can tailor their messaging to meet the needs and capabilities of potential clients.

In contrast, while Job Level is also a relevant metric for targeting on LinkedIn, it is not the selected correct answer in this context. Personal Interests, while important in broader social media targeting strategies, are generally not a primary focus for LinkedIn due to its professional nature. Customer Reviews do not serve as a targeting option on LinkedIn and are more suited to evaluation of products and services rather than a way to reach an audience. Therefore, Company Size is the most suitable and relevant targeting option for LinkedIn users.
