CPL (Cost Per Lead) — cost of acquiring a lead

What is CPL?

CPL (Cost Per Lead) is the cost of acquiring a single lead — a potential customer who has provided their contact details (form submission, registration, quote request). CPL is a key metric in B2B marketing, where the campaign goal is not an immediate sale but acquiring a contact for further nurturing by the sales team.

Formula

CPL = Total campaign cost / Number of leads acquired

Example: you spend 10,000 PLN on a Google Ads campaign and acquire 50 leads -> CPL = 200 PLN.

Why does it matter?

• Budget optimization — you know how much it costs to acquire a customer from each channel
• Channel comparison — CPL from SEO vs PPC vs email marketing
• Forecasting — knowing CPL and the lead-to-customer conversion rate, you can calculate the required budget

How to lower CPL?

1. Optimize landing pages — better CRO = more leads from the same traffic
2. Target more precisely — narrower audiences = fewer clicks, but higher quality
3. Invest in SEO — organic traffic lowers CPL over the long term
4. Lead magnets — valuable content in exchange for contact details
5. Remarketing — remarketing to people who have already visited your site
