What does conversion tracking on LinkedIn help advertisers measure?

Conversion tracking on LinkedIn allows advertisers to measure the actions taken by users after clicking on their ads. This tracking provides valuable insights into user behavior, such as whether they completed a purchase, signed up for a newsletter, or filled out a form. By understanding these actions, advertisers can garner more information about the effectiveness of their campaigns in driving desired outcomes and can make data-driven decisions to optimize their advertising strategies.

In contrast, measuring ad spend effectiveness is more about assessing the return on investment rather than specific user actions. Overall impressions reflect the number of times an ad is displayed, which does not provide insight into user engagement or conversion. Similarly, the number of followers gained is a metric focused on social media presence rather than specific user interactions prompted by advertisements. Therefore, option B is the most relevant and targeted measurement for understanding the efficacy of an ad campaign.
