What is Cost Per Lead (CPL)?
Cost per lead (CPL) is the average amount you spend to acquire a single lead - a person who has expressed interest in your product or service. It's calculated by dividing your total marketing spend by the number of leads generated in the same period.
Formula: CPL = Total Ad Spend ÷ Total Leads
CPL is most useful when compared to your customer lifetime value (LTV). A £200 CPL might be unprofitable for a £300 product but highly profitable for a £2,000/year SaaS subscription. The target is typically CPL < 10–20% of LTV.
How to Reduce Your Cost Per Lead
Improve landing page conversion rate
The fastest CPL reduction is getting more leads from the same spend. Illustrative example: a 1% CVR improvement on a £5,000/month campaign can reduce CPL when it produces more leads from the same spend.
Tighten audience targeting
Reduce wasted impressions by refining your audience. Add negative keywords (Google), exclusion audiences (Meta), or tighten job title targeting (LinkedIn).
Test ad-to-landing-page message match
When ad copy and landing page headline don't align, bounce rates spike. Ensure the promise in your ad is the first thing visitors see on the page.
Reduce form friction
Every extra form field increases drop-off. If you're collecting leads, ask for the minimum - email or name + email. Qualify leads later.
Diversify to lower-CPL channels
Organic search and email marketing consistently produce CPLs 5–10× lower than paid social. Investing in content compounds over time.
