Research Question:

“Are negative adverts more likely to be successful in Propaganda? “

How effective is an advert in relation to its positivity (negativity)?

How do we measure effectiveness?

We have access to AD_Click and AD_Impression in our data and we can calculate Click Through Rate measure to compare the success or effect of the advert. CTR = ClicksImpression

To measure campaigns’ success based on CTR plus Amount of Money spent (In other words, which campaigns were more affordably successful).
