Start with the decision you need to make
Tracking should answer a business question. That might be which campaign creates qualified enquiries, which source produces purchases, or where leads stop progressing after acquisition.
Preserve first-touch and latest-touch context where useful
Different attribution views answer different questions. Preserving campaign context before a lead crosses into another system can make later reconciliation more reliable.
Connect forms, calls and platform events
A complete journey may include a website form, a phone call, a course-platform signup, a purchase or a CRM status change. The implementation should connect only the events that materially improve decision-making.
Do not replace working tools without a reason
The integration layer should preserve useful systems and fill the missing connection. A new CRM, call platform or analytics tool is not automatically the solution when the real problem is an incomplete handoff.
