Custom Intent Audience best described as:

• A. Similar Audiences
• B. Define and reach people that have the intent to purchase, updated in real-time. Simply enter keywords or URLs that best represent your audience or choose from one of our auto-created audiences.
• C. Demographic Audiences
• D. Affinity Audiences

Answer: (B)

Custom Intent Audiences target people who are actively researching or in the market for your product, based on signals you define. You shape this audience by entering keywords or URLs that represent the topics or buying intent you care about, or you can choose from auto-created options. This approach reaches users while they’re showing purchase intent, often in real time, rather than targeting broad interests or demographic traits.

This differs from Similar Audiences, which looks for people like your existing customers; Demographic Audiences, which filter by age, gender, and other static traits; and Affinity Audiences, which covers broad, long-term interests. The strength of Custom Intent is its focus on current intent signals that you control through keywords and URLs, allowing more precise and timely targeting.
