Varun's response does not address the question regarding SEO and SEM strategies. Instead, he focuses on technical aspects of developing an e-commerce mobile application, which is irrelevant to the inquiry about enhancing product visibility and market reach. This indicates a misunderstanding of the question's focus and a missed opportunity to showcase his experience with digital marketing strategies. A more effective response would have included a specific example of how he employed SEO and SEM strategies, detailing the methodologies used and the measurable outcomes achieved in terms of traffic or sales metrics. For improvement, Varun should focus on articulating a relevant narrative that highlights his marketing skills and the impact of his strategies on product visibility.
