Marketers often struggle with making changes to their strategies due to the perceived risk of negatively impacting the business. However, incrementality testing can help alleviate this concern by providing a clear understanding of how marketing efforts contribute to business outcomes.
According to MarTech, incrementality testing offers a psychological advantage to marketers by giving them the conviction to make changes. This is because it provides evidence of the actual contribution of marketing to business outcomes, allowing marketers to challenge perceived risks and make more informed decisions.
When marketers do not know the true incremental revenue generated by their efforts, they may be hesitant to make changes to their strategies. This can lead to a lack of confidence in their decisions and a tendency to maintain the status quo, even if it is not the most effective approach.
Incrementality testing can help marketers overcome this hurdle by providing a clear understanding of the incremental returns generated by their efforts. This allows them to make more informed decisions about where to allocate their budget and how to optimize their strategies.
By understanding the underlying economics of their marketing efforts, marketers can shift their focus from defending their existing plans to evaluating opportunities for growth and improvement. This can lead to more productive conversations between marketing and finance teams, as they can discuss decisions based on the business's economics rather than just the performance of marketing tactics.
The use of incrementality testing can also change the relationship between marketing, finance, and leadership. By providing a clear understanding of the incremental contribution profit generated by marketing efforts, marketers can participate in capital allocation conversations and help determine where the business should invest its next dollar.
Ultimately, incrementality testing is not a replacement for marketer judgment, but rather a tool to help inform decisions. By combining incrementality evidence with business context and strategic judgment, marketers can make better decisions faster and drive more effective marketing strategies.
