Product Page ID (PPID) | Definition
A Product Page ID (PPID) is a parameter added to the unique URL of a custom product page (CPP) for an iOS app in the Apple App Store. Once a CPP is created and a unique URL is defined, a PPID is appended to the end of the URL. When the URL is clicked, the user will bypass the app’s default product page and go directly to the CPP.
For example: https://apps.apple.com/us/app/bike-rider/id12345678?ppid=45812c9b-c296-43d3-c6a0-c5a02f74bf6e
Once the PPID is added to the URL of the CPP, you can share that specific page with specific target audiences to increase engagement.
