Marketing Attribution Queries Project with CoolTshrts

Hello fellow learners,
I have completed my third project - Marketing attribution queries.
The project is based on helping the company answer questions to improve its marketing strategies, using attribution queries.
Your feedback is highly welcome.

  1. I want to know, is there a more efficient way to query this data?
  2. Do you agree with my findings?

Below are the links to the presentation and SQL file.
