Task: Dataset contains information about sessions and conversions of a dummy website. From the given data: 1. Describe site audience (users who are coming to the website). What are the main markets? Channels? Which of them performs the best and which are the worst? 2. Map users into useful segments that can be used for continuous performance monitoring and optimisation. 3. Compare users from France, Germany and United Kingdom. Which market seems the most promising? Why? 4. Identify at least 3 major opportunities to focus on in order to improve eCommerce performance. Include hypotheses, backing data and suggestions for further actions. You can assume that each user made only one session, so user_id = session_id You can use tools of your choice. Present your homework in any way/format you see fit. Tips: More in-depth analysis (e.g., specific data-driven observations, hypotheses, comparisons, suggestions), as well as data visualisations and summaries are highly appreciated. Some insights (e.g., certain limitations) may also be provided in the conclusions.
