How long should you typically let your conversion optimization experiments run?

1. 1 week

2. 4 weeks

3. 6 weeks

4. 2 weeks

The correct answer is: 4 weeks

Running conversion optimization experiments effectively requires a sufficient time frame to gather enough data to draw meaningful conclusions. Typically, a period of four weeks is recommended because this duration allows for the accumulation of a statistically relevant sample size, which helps in understanding user behavior and the impact of changes made in the experiment. A four-week period captures variations in user interactions, including different days of the week and potential monthly patterns. This allows for fluctuations in traffic sources and customer behavior to be considered, thereby increasing the reliability of the results. Choosing a shorter duration, such as one or two weeks, may not provide a complete picture as it might capture only limited data, leading to skewed or inconclusive results. Six weeks can offer additional time for experimentation but may introduce other variables and change conditions that can complicate the analysis, such as new traffic trends or seasonal behavior shifts. Therefore, four weeks strikes a balance, enabling a solid understanding of conversions without introducing excessive variables.
