Lucas wants to benchmark his new campaign against his previous campaigns. In particular, he wants to know how many unique users saw his content. Which of the following metrics will tell him that?

LinkedIn reach measures the number of unique members who saw an ad or campaign content. It is useful for benchmarking visibility because it shows audience exposure without counting repeat impressions from the same member. This makes it especially relevant for awareness-focused reporting and campaign comparisons. Reach is different from cost or conversion metrics because it focuses on unique audience delivery.
