Marketers must adapt to the challenges created by the COVID-19 pandemic, which accelerated innovation and changes across the world, but specifically in the digital marketing industry. Consumer demand and purchasing behaviors have changed fundamentally, and these current trends are affecting how marketers utilize digital marketing. As a result, firms must rely on innovation in marketing strategies for survival. The new expectations from consumers result in marketers determining what learning method for their staff offers a higher retention and implementation advantage to stay abreast of changes in their industry. This study analyzed employees' preferred learning methods in the digital marketing sphere. This study adds to the body of knowledge on determining the retention and implementation of two learning methods: simulation training and case study learning. These two learning methods in relation to marketing professionals led to the generation of recommendations for employers to improve learning retention for their employees. To this end, a primary research question was identified: How does the selection of a learning method for marketing professionals improve the employees' retention and implementation of new material taught? Other related research areas were also explored, namely, whether age, experience, or gender impact the preferred learning material and whether different marketing categories resonate with different learning methods, resulting in more productive results.
