Coarse Conversion Value

Updated on Jun 4, 2026

Learn what coarse conversion value means in SKAdNetwork, how privacy-preserving attribution limits detail, and why mobile teams need careful event mapping.

What Is Coarse Conversion Value?

Coarse conversion value is a privacy-preserving attribution signal in Apple's SKAdNetwork system. Instead of reporting detailed user-level behavior, a coarse value represents broad conversion quality.

Apple documents SKAdNetwork.CoarseConversionValue and APIs that update postback conversion values with a coarse value. Google Analytics Admin API documentation for SKAdNetwork conversion value schemas also references mapping events to coarse and optionally fine-grained conversion values.

In practical mobile marketing, coarse values are often interpreted as broad levels such as low, medium, or high quality.

How Coarse Conversion Value Works

Coarse conversion value may be used when detailed conversion values are not available or when privacy thresholds limit reporting detail.

Teams may map broad outcomes such as:

• Low: install but little engagement
• Medium: onboarding or early app action
• High: purchase, subscription, or strong activation

The mapping should match the business model. A game, ecommerce app, SaaS product, and marketplace may define quality differently.

Why It Matters for Mobile Teams

Mobile campaign teams need attribution signals, but privacy frameworks limit the amount of detail available. Coarse conversion value helps teams make decisions without exposing user-level behavior.

For campaign optimization, this means teams should optimize toward meaningful broad outcomes rather than raw installs alone.

For cloud phones, operational review can help explain what happens inside mobile workflows, but it should not be confused with user-level attribution data from SKAdNetwork.

Practical Evaluation

Teams should ask:

• What does low, medium, and high mean?
• Which app events map to each level?
• Are mappings documented?
• Are privacy thresholds understood?
• Are campaign reports interpreted correctly?
• Are installs being compared with retention?
• Does the conversion mapping reflect business value?
• Are MMP and analytics settings aligned?
• Are iOS attribution limits explained to stakeholders?

Coarse values are useful only when the mapping is intentional.

Teams should also explain reporting uncertainty. A coarse value can guide campaign decisions, but it should not be presented as the same level of detail as user-level analytics or deterministic attribution.

When stakeholders understand the limits, they make better budget and optimization decisions.

How MoiMobi Fits

MoiMobi supports mobile workflow review and account operations. Coarse conversion value belongs to the attribution and campaign measurement layer, while MoiMobi supports the operational layer around Android execution.

Teams should use both responsibly: attribution for campaign learning, workflow review for operational understanding.

Bottom Line

Coarse conversion value is a broad, privacy-preserving SKAdNetwork attribution signal.

For mobile teams, it helps evaluate outcome quality when detailed attribution is limited, but it needs careful mapping and context.
