When thinking about tar getting,what would be considered a restrictive targeting option?

Interests are considered a restrictive targeting option because they narrow the audience to users who have shown an affinity for specific topics. While this can be effective for highly niche campaigns, it significantly reduces the potential reach. Keywords, in contrast, are generally broader as they capture users actively searching for or discussing certain terms, offering more flexibility. Events are also broader, targeting users based on their engagement with real-world or online happenings, which can encompass a wider audience than specific interests.
