What can publishers achieve by implementing audience extension?

Implementing audience extension allows publishers to extend their reach beyond their own website, showcasing their content and advertising to users across different platforms and networks. This strategic approach enables publishers to monetize their audience more effectively, potentially leading to ad-free sites supported through enhanced revenue generated by this extended reach.

By leveraging audience extension, publishers can tap into a broader audience landscape, allowing them to serve and display ads even when users are not directly engaging with their content. This not only increases the visibility of their inventory, but also creates additional revenue opportunities as they can charge for impressions across various outlets.

The other options do not align with the primary benefits of audience extension, primarily focusing on aspects that do not contribute directly to the revenue generation or audience growth that the strategy aims to achieve. While higher costs for advertisements and complications in site management or reduced visitor engagement might imply challenges or trade-offs associated with some advertising strategies, audience extension is fundamentally about maximizing publisher visibility and revenue through audience insights and targeted advertising practices.
