X's new AI feature for creating ad audiences allows advertisers to describe their target audience using conversational descriptions. The AI system then generates a pool of the most relevant X users to target. For example, if an advertiser describes wanting to reach 'users who are leaders in technology', X's AI matching system will provide an ad audience based on that description, including an overview of top users, their interests, locations, etc. Advertisers can refine their targeting by adding more to their description, without needing in-depth knowledge of specific targeting and audience terms.

To refine ad targeting with X's AI audience feature, advertisers can add more details to their audience description after the initial audience is generated. This allows them to refine their targeting further, tailoring the audience to better match the advertiser's needs. The system provides flexibility and simplicity, enabling advertisers to adjust their audience without requiring extensive knowledge of targeting terminology.

The availability of X's AI audience feature for advertisers has been announced as 'coming soon', but a specific release date has not been provided. Advertisers and interested parties will need to stay updated with X's announcements to find out when the feature will be made available in the app.

The potential benefits of using X's AI audience matching and placement tools include a 10% increase in click-through rates and a 16% increase in conversions, on average, as reported by the platform. These improvements suggest that advertisers could see more effective ad campaigns and better audience targeting, leading to more valuable outcomes for their advertising efforts on X.

Some advertisers are still avoiding X despite the introduction of the new AI audience feature due to concerns about the platform's revised view of moderation and Elon Musk's controversial posts. These issues have not been addressed, which may affect advertisers' decisions on whether to use X's advertising options, regardless of the new feature's potential benefits.
