When determining the best product to promote, it is true or false that you should always promote the product which provided the biggest lift?

Promoting the product that provided the biggest lift may not always be the best strategy because the lifting effect could be a result of temporary factors rather than sustainable demand. Evaluating a product solely based on a short-term increase in sales does not account for several key elements, such as market trends, customer preferences, and the overall market environment.

For instance, a big lift might occur due to an effective but potentially one-off marketing campaign or seasonality rather than long-term consumer interest. It is crucial to consider the product's long-term viability, how it aligns with customer needs, and competitive landscape.

Additionally, other products may offer better margins, broader target audiences, or longer-lasting sales opportunities even if they did not yield the highest lift in sales during a specific period. Therefore, comprehensive analysis and market conditions should guide decisions about which product to promote rather than focusing solely on short-term performance metrics.
