Running marketing experiments before investing in big changes to your strategy or approach can help you determine if the proposed changes will be successful before committing to them. Experiments allow you to test out new ideas and tactics, measure the results, and evaluate whether the changes are worth the investment. This can help you save time, money, and resources by avoiding costly mistakes or inefficient strategies. Experiments also provide valuable insights into customer behavior and preferences, allowing you to make more informed decisions about how to move forward.
