Stories

Stories ads are 9:16 full-screen creatives — image or video — that appear between users' stories on Instagram, Facebook, and Snapchat. A format is a set of constraints — ratio, duration, safe area, sound expectation and user intent. The same message performs very differently across two placements because the viewer's posture is different. Building for the placement rather than resizing into it is most of the difference between fine and good. Read it next to Reels, Aspect Ratio, Safe Zone.

Design for the dominant placement first, then adapt deliberately: reframe rather than letterbox, keep key content clear of overlays, and assume sound is off until proven otherwise. Where a placement has a distinct native language, respect it instead of exporting one master everywhere.

Report by placement, not just campaign. A blended cost per result hides the placement subsidising or draining the set. Watch early-view retention for video placements and thumbstop for feed placements, then adjust the creative rather than only the bid. Why this matters commercially: Stories combine full-screen attention with tap-to-swipe interaction, making them one of the highest-intent social placements.

Xeli renders each concept into every placement's spec in one pass — correct ratio, correct safe zone, correct file requirements — so a campaign ships complete instead of arriving in fragments as resizes trickle in. In the context of ad formats & placements, that means the concept stops being something a person re-applies by hand every campaign and becomes a rule the system enforces on every asset it produces.

The recurring problems are predictable: recycling feed creative into stories; ignoring the swipe-up cta area; skipping sound design. Each of these is a process gap rather than a knowledge gap — which is why the fix is usually a checklist, a template or an automated rule instead of more training.
