What is Cost per lead (CPL)?
The average amount you spend on advertising to generate one lead, meaning one interested contact.
Cost per lead (CPL) is the average amount of money you spend on advertising for every lead you generate. A lead is someone who shows interest and shares their contact information, for example by messaging you on WhatsApp, filling out a form, or requesting more details. You calculate it by dividing your total ad spend by the number of leads you brought in during that period.
Why it matters to your practice
For a private practice or clinic, CPL is the most direct way to tell whether your advertising is working without guessing. It shows what it costs to get an interested person to raise their hand, and when you compare that number against what a patient is worth to you, you can decide whether to spend more, adjust the campaign, or change the message. A low CPL that produces low-quality leads is not a win, so this number only makes sense alongside how many of those contacts actually book and show up. Watching it keeps you from overspending on Meta or Google to attract curious browsers who never become patients.
Example
A dermatologist in Guadalajara puts 6,000 pesos into a Meta campaign promoting acne consultations. Over the month she gets 40 WhatsApp messages from people asking for details and sharing their contact info. Her cost per lead is 150 pesos (6,000 divided by 40). If 12 of those 40 leads book and attend a consultation, she can weigh that 150 pesos per lead against what each new patient is worth to decide whether the campaign is paying off.
