Quick answer

A Testing Period is a designated amount of time during which you run an experiment or test, like an A/B test, to evaluate the performance of a particular marketing campaign, webpage, or feature. The length of a testing period can vary based on the objectives of the test, the traffic your website receives and the statistical significance you want to achieve.

Key takeaways

  • Testing Period helps define how an experiment is planned, run, or interpreted.
  • Clear terminology reduces confusion between marketers, analysts, designers, and developers.
  • Documenting it before launch makes results easier to trust and compare later.
