Target CPL in LSA and Target CPA in Google Ads both tell the platform what you are willing to pay for a required result, but they optimize for different outcomes. Target CPL focuses on the cost of generating a lead, whereas Target CPA focuses on the cost of acquiring a conversion, such as a completed form, call, purchase, or other conversion action.
For example, if your LSA Target CPL is $50, the goal is to generate leads around that average cost. If your Google Ads Target CPA is $50, Google is trying to get conversions around that target, based on the conversion actions you have defined.
The key difference is like,
Target CPL: Optimizes around leads.
Target CPA: Optimizes around defined conversions.
LSA: The lead itself is generally the primary result that is being optimized.
Google Ads: You can optimize toward deeper actions, such as qualified leads or purchases, if conversion tracking is set up correctly.
So, Target CPL is like asking, “How much should I pay for a lead?” and Target CPA asks, “How much should I pay to acquire a customer or conversion?” that is the difference.
