How It Works

Cost per Lead divides your total Meta ad spend by the number of lead events tracked via the Meta Pixel or Conversions API. A lead event fires when someone submits a form, signs up for a newsletter, or completes another lead capture action on your site. Lower CPL indicates more efficient lead generation.
