What happens when Louise enables Audience Expansion?

When Louise enables Audience Expansion, it significantly enhances the reach of her advertising campaigns by allowing her ads to be shown to new potential customers who share similar characteristics with her existing audience. This feature uses LinkedIn's targeting capabilities to identify and reach individuals who may not have previously engaged with her content or brand but are likely to be interested, based on their professional profiles and behaviors.

By leveraging Audience Expansion, advertisers can tap into a broader demographic, increasing brand visibility and potentially leading to higher engagement rates and conversions. This strategic move can be particularly beneficial for businesses looking to grow their customer base, as it aids in discovering and converting audiences that might have been overlooked.

The other choices do not correctly capture the primary function of Audience Expansion, which specifically focuses on enhancing audience reach rather than restricting it, reducing ad spend, or limiting ads to only top performers.
