How do you calculate cost per acquisition?

In the paid acquisition market, clicks seem to be the holy grail. However, in case you think of it, clicks only inform you if visitors reach your content or not. They do not tell you whether they stay or not. In this case, how do you know that your content is engaging enough to convince your customers to stay and purchase your services or products?

The best way to measure your content’s converting abilities is the cost per acquisition. Then, in this part, you will be shown how to calculate cost per acquisition and how its bidding process works.

Most acquisition marketers would rather the CPA pricing model. This is because they are able to set their definition of each acquisition before they begin advertising and need to pay as their desired action or acquisition occurs.

In fact, the CPA auctions are not similar to your particular auction for the antiques. Advertising platforms such as Google would love to increase their level of the playing field as it comes to leverage the size of their own reach. Hence, instead of the fact that the highest bidder often wins the auction, the bidder with the highest Ad Ranks will always win.

AdRank’s formula is multiplying your maximum CPA bid with the quality score of your own ad that is measured by calculating your page’s relevance to user experience, click-through-rate, and the keyword. It means that organizations are unable to acquire the top ranking for keywords they wish since they have the largest ad budgets. As a result, their content needs to be engaging.

To calculate Cost Per Acquisition for your advertisement of the campaign’s cost, you had better take total advertising spend, then divide it by the quantity of acquisition created.

USD500 cost of campaign/ 20 conversions = USD 25CPA. Then, in case you responded to USD25, you are totally correct.

Reading up to know, you might have an arising question. How do you know if this CPA is good or bad? In fact, CPA and CLV (Customer Lifetime Value) are connected closely. CLV represents the whole money a certain customer is about to spend over his lifetime relationship on your own site.

Here is another example of CPA calculation:

Imagine that you are the store owner of an eCommerce store called Mark’s shirts that sells men’s dress shirts. You run this campaign and spend USD1,000. And after this campaign, you already sell 10 shirts on your own site. So what is the CPA?

Here is the answer: USD 1,000 spent/ 10 sales = USD 100 CPA. For this campaign, it costs USD 1,00 on an average for conversion.
