A metric used in digital advertising to measure the cost of each desired action that is taken by a user after clicking on an ad. An action could be a purchase, a form submission, a sign-up, or any other conversion the advertiser has identified as a campaign goal. Similar to ECPC, ECPA considers not only the cost per click but also the campaign's effectiveness in driving desired actions. It is calculated by dividing the campaign's total cost by the total number of desired actions it generates.
How Cost Per Action Works
Cost Per Action (CPA) is an online advertising measurement and pricing model referring to a specified action, for example, a sale, click, or form submit (e.g., contact request, newsletter sign up, registration, etc.). Direct response advertisers often consider CPA the optimal way to buy online advertising, as an advertiser only considers the measured CPA goal as the important outcome of their activity. The desired action to be performed is determined by the advertiser.
- Advertiser benefit: Advertisers only pay for leads that result in the desired action such as a sale. This removes the risk for the advertiser because they know in advance that they will not have to pay for bad referrals.
- Affiliate benefit: It encourages the affiliate to send good referrals.
How to Calculate ECPA
ECPA is calculated by dividing the campaign's total cost by the total number of desired actions it generates. This metric helps marketers understand the true cost of acquiring desired actions through their ad campaigns.
Importance of ECPA
