The four metrics that matter

Understand what each number means and why it drives your campaign decisions.

Return on Investment

The ratio of net profit to ad spend. A 200% ROI means every $1 spent returns $2 in profit. Industry average is 100-200%.

Cost Per Lead

Total ad spend divided by leads generated. Tells you how efficiently your campaigns are attracting potential customers into the pipeline.

Customer Acquisition Cost

Ad spend divided by paying customers. The single most important metric for unit economics must be lower than customer lifetime value.

Leads → Customers

The percentage of leads who become paying customers. A low conversion rate signals friction in your funnel, not just a traffic problem.

Pro tip

A healthy ROI alone doesn’t tell the full story. Always pair it with CAC and conversion rate. A 300% ROI with a $500 CAC may be worse than a 150% ROI with a $50 CAC if you’re scaling. Use all four metrics together.

Stop guessing

Every ad dollar should be tracked

Plug in your real campaign numbers and walk away with investor-ready metrics.
