Install a visitor ID tag: every platform
33 platform guides. Each one gives the exact place your visitor identification tag goes on that platform, the plan tier that allows custom code where the platform gates it, the platform-specific mistake that silently breaks tracking, and how to verify the tag fires. Every step comes from the platform’s own documentation, checked on the date shown. After installing, measure what you can actually expect with the match-rate calculator.
