Beyond basic demographics, which specific behavioral pattern on Quora most directly indicates a user's receptiveness to targeted advertising?

Repeated engagement with specific topics or 'Spaces' through upvoting, commenting, and actively following them is the strongest indicator. This goes beyond simple interest because it demonstrates active participation and a sustained focus on the subject matter. Users who actively engage are more likely to notice and consider targeted advertising related to those topics. Basic demographics provide a general overview, but engagement indicates real-time interest and potential purchase intent. For instance, someone who frequently upvotes answers about 'electric vehicles' in a 'Sustainable Living' Space is demonstrably more receptive to EV-related advertising than someone who simply lists 'environmentalism' as an interest in their profile.
