Getting the Most from SKAN’s 6 Bits: Smarter Conversion Mapping Starts Here

Hey, there, marketer,

      If you’re running user acquisition (UA) campaigns on iOS, you’ve probably come face-to-face with the conversion value challenge in SKAdNetwork (SKAN). With only 6 bits to work with (that’s just 64 values), marketers are asked to tell a meaningful post-install story—without IDs, user-level data, or real-time feedback.

 

Let’s break down how to make the most of those 6 bits, and share some best practices for smarter SKAN conversion mapping.

Why does Conversion Mapping Matter?

SKAN doesn’t give you rich post-install data by default. Instead, it lets you assign values (0–63) to user actions taken within the first 24–72 hours. These values are your only way of knowing what happened after a user installed your app.

 

So, how you map these values directly affects how much insight you can extract from iOS installs. Done well, it tells you which ad campaigns brought invaluable users. Done poorly, it’s just 64 wasted numbers.

Best Practices for Conversion Mapping in SKAN

1. Keep It Simple, Then Iterate

Start small. Don’t try to use all 64 values right away. Group users into clear segments (like: registered, made a purchase, or reached level 3). Once you’ve got solid data flowing, you can expand and refine.

2. Use a Binary Structure

Think of your 6 bits as a string of on/off switches. Many top MMPs recommend using a binary approach—splitting bits between revenue, engagement, and retention.

Example:

• Bits 1–2: Revenue buckets (e.g., $10)
• Bits 3–4: In-app activity (e.g., tutorial complete, session length)
• Bits 5–6: Retention markers (e.g., opened app on day 1 or 2)

3. Align Mapping With Your Funnel

Map conversion values to real user behaviour—not just random events. What are your key moments in the first 24–72 hours? Prioritize those that signal long-term value.

4. Use Flexible Buckets for Revenue

Break your revenue down into tiers. Track general behaviour instead of precise values. Use 2–3 bits to group spenders effectively.

5. Test and Adapt Often

Your SKAN schema should evolve. Monitor your mappings every few weeks, and revise based on how users are engaging.
