Remove the non-advertising influencing factors and make appropriate measurements
The most important point in evaluating the impact of advertising on sales is to eliminate factors that affect sales other than advertising. In the conventional advertisement effectiveness measurement, based on data such as "Sales of ○% in the month when advertisement was submitted", "A person who saw the advertisement purchased ○% purchased", evaluation of the influence on sales I often do.
