Social Media Marketing Performance Analytics Challenge

Join this challenge to take the role of a data analyst for a global IT company actively running content campaigns across multiple social media platforms. You’ve been given a 2024 dataset capturing detailed records of post-level performance metrics, platform details, content types, and geographic reach.

The dataset consolidates information about various posts published across TikTok, Instagram, LinkedIn, and X.com. It includes metadata such as post type (video, carousel, text), content category (product promotion, educational, entertainment), publishing times, and associated hashtags. It also tracks performance indicators like engagement, views, impressions, clicks, click-through rates, and post reach across countries and regions.

Your goal is to build a report that reveals what makes content successful on different platforms, explains regional trends in engagement, and informs better content and platform strategy decisions.

Key questions to answer in your analysis:

• Which platforms and post types generate the highest engagement or views?
• What content categories (e.g., product promotion, educational) drive the best performance across different regions?
• How do performance metrics vary by platform, post format, or hashtag usage?
• What are the ideal days and hours to publish content for maximum engagement?
• Are there regional differences in engagement and click-through performance?
• What hashtags are most effective in increasing impressions or clicks?
• Which countries or regions consistently show high video view counts or live stream interest?
• Are there correlations between engagement levels and content categories or publishing time?
• How do organic vs. promoted content types compare in terms of reach and performance?

These questions serve as a launchpad for your analysis, feel free to go beyond them and craft your own insights based on the story you want to tell with the data.

Technical requirements

• Build your report using only Power BI
• The number of pages in the report is not limited
• At least one report page has to contain a minimum of 2 ZoomCharts Drill Down Visuals. See a practical guide on Drill Down Visuals here
