# Default to Timing Choice When Inventory is Shallow

## Action: Default to Timing Choice When Inventory is Shallow

When serving a niche demographic or operating in a context with limited advertiser demand, a platform may lack a deep inventory of relevant ads. In that case, offering [[concept-ad-content-choice]] forces the platform to stretch thin inventory into low-quality options or unfamiliar brands — which *raises* the [[concept-cognitive-burden-of-choice]] and can trigger the failure conditions in [[claim-content-choice-failure-modes]].

**Default instead to [[concept-ad-timing-choice]]**, which requires only one ad to function effectively and never asks the viewer to comparison-shop.

**Action:** Use timing choice when relevant ad inventory is scarce or available brands are unfamiliar.

**Outcome:** Maintains user agency without exposing operational constraints or causing cognitive overload.

This is axis 3 (operational constraints) of [[framework-ad-control-deployment]].
