The direct conversion rate measures how often shoppers end up purchasing the advertised product after clicking on the ad. Direct conversion rate is the number of direct conversions divided by the number of clicks (Direct conversion rate = direct conversions ÷ clicks)
The cost per direct conversion is how much each direct conversion costs, on average. It is the amount spent on your ad divided by the number of direct conversions attributed to the ad (Cost per direct conversion = expense ÷ direct conversions)
The direct return on ad spend, or direct ROAS, measures how much revenue is generated from sales of the advertised product, relative to the cost of the ad. It is the amount of sales revenue for the advertised product attributed to the ad, divided by the amount spent on the ad (Direct ROAS = direct GMV ÷ expense)
The direct advertising cost of sales, or direct ACOS, measures how much your ad costs relative to the revenue generated from sales of the advertised product. It is the amount spent on the ad divided by the amount of sales revenue for the advertised product that is attributed to the ad (Direct ACOS = expense ÷ direct GMV × 100)
The click-through rate (CTR) measures how often shoppers end up clicking on your ad after seeing it. It is the number of clicks on your ad divided by the number of times your ad is seen (CTR = clicks ÷ impressions)
The conversion rate measures how often shoppers end up purchasing something from your shop after clicking on your ad. It is the number of conversions attributed to your ad divided by the number of clicks on the ad (Conversion rate = conversions ÷ clicks)
The cost per conversion is how much each conversion costs, on average. It is the amount spent on your ad divided by the number of conversions attributed to the ad (Cost per conversion = expense ÷ conversions)
Return on ad spend (ROAS) measures how much revenue is generated by your ad relative to the cost of the ad. It is the amount of sales revenue attributed to your ad divided by the amount spent on the ad (ROAS = GMV ÷ expense). (Note: We recommend monitoring ROAS trends on a weekly basis.)
The advertising cost of sales (ACOS) measures how much your ad costs relative to the revenue the ad generates. It is the amount spent on your ad divided by the amount of sales revenue attributed to the ad (ACOS = expense ÷ GMV × 100)
