Ad Formats & Placements

Search Ad

Text-based ads triggered by keyword queries on search engines.

Search Ad is a ad formats & placements concept that ecommerce teams touch every week, usually without agreeing on a definition first. This page sets out what it means, how to apply it at catalog scale, what to measure, and where it breaks.

Definition

Search ads are text or extended text ads triggered by user queries on Google, Bing, and other search engines — the classic intent-based ad format.

Why it matters

Search captures demand at the exact moment of intent, producing the highest CVR of any placement — but caps scale at existing demand.

Search Ad in practice

Search ads are text or extended text ads triggered by user queries on Google, Bing, and other search engines — the classic intent-based ad format. 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 Shopping Ad, Google Ads.

How to get it right

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.

What to measure and watch

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: Search captures demand at the exact moment of intent, producing the highest CVR of any placement — but caps scale at existing demand.

Where Search Ad sits in an agentic creative workflow

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.

Failure modes worth naming

The recurring problems are predictable: bidding on brand terms without incrementality tests; ignoring match type strategy; skipping ad extensions. 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.

Common mistakes

  • Bidding on brand terms without incrementality tests.
  • Ignoring match type strategy.
  • Skipping ad extensions.
