Which of the following best describes audience extension?

Audience extension refers to a digital marketing strategy that allows advertisers to reach new audiences beyond their existing customer base. This approach leverages data and technology to identify and engage individuals who may be interested in a brand's products or services but are not currently in their audience database. By utilizing audience extension, marketers can effectively broaden their target reach and drive brand awareness among potential customers who share similar characteristics with their existing consumers.

This method contrasts significantly with limiting audience interaction or focusing solely on email marketing. Audience extension utilizes various digital platforms and channels, creating opportunities for advertisers to engage with potential new customers across display, social, and other online environments. It enhances the effectiveness of advertising campaigns by optimizing audience targeting and facilitating growth in customer acquisition strategies.
