When conducting A/B tests for digital marketing, it's important to keep in mind the following best practices:
- Only test one variable at a time to ensure accurate results
- Test for a long enough period of time to gather significant data
- Use a large enough sample size to ensure statistical significance
- Pre-test to ensure that the variant is functionally sound before running the actual test
- Use a randomized sample to avoid bias
- Avoid peeking at the data during the test to maintain scientific integrity
Here is a great process for testing. Use the example below and then download this blank card.
