Marc started a Facebook page at the beginning of last year and spent a total of $ 500 boosting ads. As a result, we saw an increase of 50 new customer orders through the website - the new customers mentioned they learned about us through Facebook and spent an average of $ 30/ order . What does this tell you about the effectiveness of our ecommerce efforts? AA Surf's Up should increase the markup on its products to compensate for the cost of the ads. Surf's Up is incurring $ 10 of customer acquisition costs to attract each new customer through Facebook ads. Surf's Up should continue boosting ads on Facebook. Surf's Up is now generating $ 20 of profit per new customer order
