This article provides guidelines for visitor stitching.
The following are important guidelines for visitor ID attributes and visitor stitching:
A visitor ID attribute must have at least 3 unique characters and be at least 6 characters long.
Learn more about visitor ID attribute requirements.
- Case Sensitive
Visitor ID attribute values are case sensitive so,
UserName@example.comis different from
email@example.com. If the attribute values contain these variations, use the lower-case enrichment to normalize them.
- Multiple IDs
Multiple visitor ID attributes are evaluated as an OR condition in order of attribute ID from lowest to highest (oldest to newest).
Only user identifiers that are guaranteed to match the visitor across devices should be used for visitor ID attributes.
- Stitched Visitor Profile
When multiple visitor profiles are stitched, the original profiles remain and a new visitor profile is created to store the stitched profiles.
- Avoid Test Data
Be careful not to capture default or test values in your user identifiers, such as,
- Shared IDs
Before stitching is enabled, determine how to handle shared IDs, such as those used at libraries or universities, so that multiple visitors are not stitched inadvertently.
