The frequently asked questions on CPA and how to best utilise this metric.

Why Track Cost Per Acquisition?

CPA helps you understand how much you’re spending to acquire a customer or lead. Whether you’re managing ad placements across different channels, tweaking your bidding strategy, or testing keyword competition, CPA keeps your focus on results, not just impressions.

Knowing your CPA helps with:

  • Setting realistic advertising budgets
  • Comparing click-through rates (CTR) with conversion rates
  • Improving user experience to better campaign performance
  • Aligning your campaign objectives with actual business objectives

CPA refers to how much you spend, on average, to gain one conversion. It’s a core metric in digital advertising that helps measure the effectiveness of your advertising campaign.

It calculates the total cost per acquisition based on your total ad spend and number of conversions. It’s a fast way to check how efficiently your ad campaign is converting.

Tracking CPA shows you which social media platforms, keywords, or creatives bring in results. If your conversion rates are low and CPA is high, it might be time to adjust your user experience or test new ad placements.
