In my previous role as a data analyst intern, I worked on optimizing a marketing campaign for a motorcycle brand. We aimed to increase engagement and conversion rates through targeted advertising. To achieve this, I focused on key metrics such as click-through rates (CTR), conversion rates, and customer acquisition costs. I analyzed data from various sources, including social media platforms and the company's website, to identify patterns and trends in customer behavior. Based on the insights, we adjusted our targeting strategy to focus on demographics that showed higher engagement. We also refined our ad content to better resonate with our audience's interests. As a result, we saw a significant improvement in CTR and a reduction in customer acquisition costs, leading to a more successful campaign overall.
