Which demographic feature can be targeted through detailed audiences?

The correct answer is related to targeting options available through detailed audiences in advertising platforms. Age is one of the fundamental demographic features that can be specifically targeted in ad campaigns. Advertisers can tailor their messaging and content to reach audiences of different age groups, which allows for greater relevance and improved engagement with the intended audience.

When targeting by age, advertisers can define their audience based on specific age ranges, ensuring that their ads are shown to individuals who are most likely to be interested in their products or services, depending on their life stage. This is particularly important in crafting marketing strategies, as different age groups may respond differently to advertising messages and product offerings.

The other options, such as job titles, brand loyalty, and ad spend, while relevant in broader targeting strategies, are not classified strictly as demographic features in the same way age is. Job titles would fall under professional characteristics, brand loyalty relates more to consumer behavior, and ad spend pertains to budgeting strategies rather than targeting demographics directly.
