An advertiser recently implemented the Pinterest tag and notices conversions are not being reported accurately for people accessing Pinterest on multiple devices.What should the advertiser do?

Enabling enhanced match is the correct solution because it allows Pinterest to match website conversions to Pinterest users more accurately, even across multiple devices. This is achieved by securely hashing and sending customer data (like email addresses) from your website to Pinterest. This additional data helps bridge gaps in cross-device tracking, improving conversion attribution. Setting up a new tag is unnecessary; the existing tag can be enhanced. Modifying the event code to track more parameters might provide more granular data but won't inherently solve the cross-device matching problem without enhanced match. Modifying the base code to include multiple tag IDs is incorrect; a single tag ID is typically used per advertiser, and adding more wouldn't address the cross-device attribution issue.
