Cost per Purchase decreases due to strong increase in conversion rates, partially offset by increased CPC

Overall, Cost Per Purchase decreased an avg. of 15% in 2019 & 2020 in the runup to Black Friday. 

What are the driving forces? Well first, we see a big increase in conversion rates of about 60%. Shoppers are much more likely to buy and merchants are heavily investing in closing leaky funnels.

However, the CVR increase is offset by increased CPCs of about 35%, leading to the more modest decrease in CPP noted above. 

In the weekly breakdown below, you can see the avg. Cost Per Purchase drops in the two weeks prior to Black Friday and the week of Black Friday, though it increases in the week prior to Black Friday.

CPC increases due to skyrocketing CPM, slightly offset by increased CTR

The main cause was an avg. CPM increase of 52%. CTRs have been mixed the past couple years (+25% in 2020 and -15% in 2019).

On a weekly basis, CPMs & CPCs spike on the week of two weeks before Black Friday, then actually drop one week before black Friday and finally spike even sharper during the week of Black Friday.

ROAS increases due to decrease in Cost Per Purchase
