Things you did well

  • Well structured : Great initial overview of how you plan to answer the question and great structure throughout the answer 
  • Great description of the product: Good summary of the product, its objective and what it does 
  • List of metrics: You came up with good list of metrics 

Areas of Improvement

  • Description: Given this is for Facebook, submitting a post is free. 
  • Feature Goal: Choose one goal so you can easily evaluate your metrics against that goal / evaluation criteria. I would have highlighted matching buyers and sellers to trade as the product goal. 
  • Evaluate your metrics: After listing out the metrics, evaluate them based on some meaningful metric such as impact, reach, revenue impact, etc and then suggest your primary and secondary metrics to track. You won't be able to track and optimize all these metrics at the same time.
