Connecting cross-device identities

In Audience & Privacy, Identity Stitching names an audience or privacy concept. Pin the meaning down early and the strategy stays coherent.

## The mechanics

Keep this in mind.Identity Stitching is no fixed dial. How it behaves depends on your audience, your channel mix, and the strategy around it.

Think of Identity Stitching as context-bound. A small shop reads it simply; an enterprise reads it with more nuance. That is normal -- Identity Stitching is shaped by audience and channel mix. Read Identity Stitching without care and the plan wobbles; be precise and the read holds.

Keep the order simple: define Identity Stitching for your context, then decide how to act. Reverse it and the budget chases a number nobody agreed on. Start here.

## When it matters

Look at it this way.Reach for Identity Stitching when a real decision rides on it -- a budget, a metric, or a comparison. Otherwise it is reference.

Identity Stitching matters at the point of a decision. In audience & privacy, three moments come up again and again. Outside them, Identity Stitching is reference material.

1. **Setting budget.** Identity Stitching signals which line earns the marginal spend.
2. **Choosing a metric.** Identity Stitching flags whether the number you report is causal.
3. **Comparing options.** Identity Stitching stops a tidy-looking comparison from misleading.

## An example with real numbers

Read that twice.The walk-through runs Identity Stitching through work modeled on Sephora, so the concept meets real constraints.

Take Sephora. During a consented-audience rebuild, the team made Identity Stitching the deciding input, not an afterthought. They set a baseline first, agreed one definition of Identity Stitching, and only then read the result: match rates held near 70% after ATT. The number matters less than the order.
