Which strategy can effectively expand the size of an audience in digital marketing?

Adding "or" statements to detailed targeting is an effective strategy for expanding the size of an audience in digital marketing. This approach allows marketers to reach a broader group of potential customers by including multiple criteria that can be met individually. For instance, if a marketer targets people with interests in "sports" or "fitness," the audience size increases because it encompasses both groups rather than limiting the reach to those who possess both interests together.

This method contrasts with more restrictive targeting options, such as using "and" statements, which narrows the audience by requiring that all specified criteria be met simultaneously. Additionally, limiting audience selection to custom lists could significantly reduce reach, as it confines the targeting to a predefined group. Focusing on a niche market, while effective for specific campaigns, typically does not lead to an expanded audience because it aims at a more segmented section of the overall market. In conclusion, employing "or" statements expands reach by increasing potential audience intersections, making it an advantageous tactic in digital marketing.
