In addition to the sales objective, a brand can have other objectives, closer to the top of the funnel, for example exposing the message to the potential goal and obtaining incipient interactions from it. Depending on each marketing objective, there are different types of CPAs, each adapted to measure the cost of the different types of customers. Their calculation method is similar to that described above.

How can you improve your CPA?

There are several ways in which you can improve your CPA. Here are some suggestions:

• Improve the quality of your marketing campaigns. Make sure you have checked all the potential variables of success of the advertising campaigns you are performing: which are well direct and relevant for the destination audience, that you use high quality images and text and include a clear action.
• Improve the conversion rate of your site. A site must be easy to use and have a process of completing the clear and concise order. Use convincing action impulses and offers a positive experience for visitors.
• Use the targeting options in an intelligent way to reach the ideal audience. Theoretically, more specific you are with the targeting of advertising, the more likely it is that you reach people who are interested in your products or services, but not always. Currently, the new updates of the algorithms on the PPC platforms make targeting preferable as much as possible and delegate control to the incorporated tools.
• Head and optimize your campaigns. CPA is an excellent metric to constantly provide feedback on the performance of the campaign. What you need is to look closely at your campaigns and make changes to improve their performance. Use the A/B test to try different ads and destination pages.
• Monitor your CPA over time. Your CPA will change over time, so it is important to follow it closely and make changes as needed.

How does the CPA evolve over time?

In this video on how the CPA evolves over time, Taylor Holiday from Common Thread Collective states that, as a company develops, its CPA will increase, once it will pass by the customers who adopt previously.

This process is normal and it is due to the fact that at the beginning you buy mainly customers who are already familiar with your product or service (such as friends and family) and in the subsequent stages, you need many display posts to reach the most distant audience.

Taylor also gives us some suggestions on how to manage the CPA while a brand develops.
