What is the cost per lead?
The cost per lead is the average cost for each new lead you get in your ad campaign. This lead metric measures how cost-effective your marketing campaigns are so that generating leads is worth the ad spend. Much like CPM or CPC It's also an online advertising pricing model, where the advertiser pays for a sign-up from a potential customer instead of a view or a click.
CPL is not to be confused with these other similar acronyms in digital marketing:
CPA: Cost Per Acquisition
CPC: Cost Per Click
CPM: Cost Per Thousand
CRM: Customer Relationship Management
