Meta — Explore vs Feed delivery

Instagram Explore is discovery inventory — different CPM, creative fit, and objective mapping than home Feed. When to split ad sets and what breakdowns to export.

Intent difference

Feed optimizes for habitual scroll in the home timeline. Explore catches high-intent browsing in the discovery grid and video surfaces — thumb-stop and hook patterns differ even when aspect ratios match.

Creative fit

Explore tolerates 1:1 grid thumbnails and 4:5 video; Reels-first creative still needs 9:16 masters when Advantage+ routes delivery to Reels from the same ad set. Check safe zones before reusing Feed assets.
