Question 1 : An ad campaign has generated 1 million ad impressions and 6000 clicks.What is the CTR (ClickThrough Rate)? (in percentage) Question 2 : An ad campaign has generated 5000 clicks and 100 transactions. What is the conversion rate (in percentage)? Question 3 : With a budget of $5000 and a CPC (Cost per click) = $0.4, how many clicks an advertiser can buy (integer without unit)? Question 4 : An ad campaign has a CTR = 0.6% and a CPC = $0.4.What is the equivalent CPM (in dollar)? Question 5 : An ad campaign has a CPC = $0.5, a conversion rate = 3% and an average transaction value of $260.What is the Cost of Sales of the campaign (cost of the ad campaign divided by the revenues generated, in percentage)? Question 6 : With a margin on revenues of 13%, an average transaction value of $290 and a conversion rate = 0.7%, what is the maximum CPC an advertiser can afford without losing money (in dollar)? Question 7 : During his browsing, a user is randomly exposed to two ad banners A & B. Those two banners are equally likely to be shown. One and only one banner is shown per page. After two pages of browsing, what’s the probability that the user was shown only banners A (in percentage)? Question 8 : A/B Testing campaign: Measuring the impact of Criteo retargeting ads compared to a control group. Number of transactions on client site : • Group A exposed to Criteo banners 600,000 • Group B Control group not exposed 50,000a. a. Is it a problem to have a control group smaller than the CompanyA group? No - what you want to know is if the transaction rate for the experiment group is significantly greater than that of the control group. As long as the results are statistically significant, the uneven sample size between groups should not be a problem. b. What incremental revenues per user CompanyA has generated for the client advertiser (in dollar, rounded to the cent)? For this question you need to first calculate the revenue per user for both groups and then take the difference between them to arrive at the incremental revenue per user. c. What total incremental revenues CompanyA has generated for the client advertiser? Total incremental revenue is simply the incremental revenue per user multiplied by the number of users exposed to Company A's retargeting. d. With $200.000 revenues following clicks on banners for group A (post click), what is the related post view (view through) effect in revenues generated by CompanyA campaign?
