Good job! Let's do one more exercise.


Create a report containing the conversion rates for weekly registration cohorts in each registration channel, based on customers registered in 2017. Show the following columns: Week, ChannelName, and ConversionRate. Format the conversion rates as percentages, rounded to a single decimal place. Order the results by week.

Stuck? Here's a hint!

Join the Customers and Channels tables to get channel names. Group by channel IDs and channel names. Calculate the conversion rates as:

ROUND(COUNT(FirstOrderId) * 100.0 / COUNT(*), 1)
