What should a conversion measurement plan include?

  • campaigns
  • measurement

The short answer

A conversion measurement plan should define the useful business outcome, the observable steps leading to it and the limits of the available data. It must distinguish user actions from completed delivery and commercial success. Give every event a clear meaning, implementation owner and verification method before relying on the reports.

What to define

Map the journey from source to destination and list the interactions that can be observed responsibly. Describe event names, triggers, consent requirements and receiving systems. Identify actions that occur outside the website, such as a later sales conversation, instead of quietly treating them as visible.

How to evaluate it

Use labelled tests to check that each event fires at the intended point and is not counted repeatedly by ordinary retries. Connect eligible outcomes to an appropriate operational record. Document changes in the setup so a later increase or decrease is not mistaken for a real business shift.

Make it concrete.

A contact button may open an email draft, while a later sent message arrives outside the website. The measurement plan should describe those as separate stages and avoid reporting the first action as a delivered lead.

Before you commission
