# Build Audience Segments for Ad Targeting

Effective advertising requires more than broad demographic targeting. Modern ad platforms reward specificity -- the more precisely you define your audience segments, the better your cost-per-acquisition and return on ad spend. But building detailed audience segments from scratch requires market research, customer interviews, and analytics deep dives that most teams skip under deadline pressure.

AI-powered audience segmentation produces structured, actionable segments that map directly to ad platform targeting options. Each segment comes with demographic boundaries, psychographic profiles, interest affinities, pain point messaging angles, and recommended channels. Instead of guessing which audiences to test, you start with research-backed segments that dramatically shorten the path to finding profitable ad audiences.
