  1. Channel selection: Which channels are working, and which are not?
  2. Price elasticity: For every dollar you spend on advertising, what is the change in sales?
  3. Channel spend: How much of the company's budget should be spend on each channel?

Summary of Analysis

The linear regression analysis showed that Youtube Ads have no significant impact on sales whereas the other 2 channels showed significance. Based on the incremental impact from the regression analysis, Google Ads had the largest impact on sales.
