## About Lead Source
Lead Source tells you which ads, pages, and campaigns actually produce paying customers — not just clicks. A single script captures the real source of every form submission and ties it to revenue in your CRM, so you can cut marketing spend that isn&#39;t producing business and double down on what is.
