How to track lead sources
Lead source tracking connects each lead to the channel that created it, all the way through to revenue. Without it, you optimize on cost per lead and unknowingly pour money into sources that produce volume but never close.
Short answer
Track lead sources by capturing where every lead came from at creation with consistent, standardized values, tying source through to opportunity and closed revenue, and reporting cost and conversion per source. This tells you which channels create pipeline and revenue, not just cheap clicks, so you can reallocate spend.
Step by step
Capture source at creation
Stamp every lead with its origin the moment it enters the system, from web forms, ads, events, referrals, or outbound, so nothing is left as "unknown."
Standardize the source values
Use a fixed, controlled list of source names. Free-text sources produce unreportable mush.
- Standard values: paid search, organic, referral, event, outbound
- Track medium and campaign for finer detail
- Never allow free-text source entry
Connect source to opportunity and revenue
Carry the source from lead to deal to closed-won so you can measure revenue by source, not just lead count.
Report cost and conversion per source
Combine spend with lead-to-opportunity and opportunity-to-win rates to get true cost per acquisition by channel.
Reallocate based on revenue
Shift budget toward the sources producing pipeline and revenue, and cut those producing only cheap, non-converting leads.
How Ardovo helps
Ardovo captures source on every lead, carries it through to closed revenue, and reports cost and conversion by channel so you optimize on pipeline created, not clicks. Rook flags sources whose leads never convert so you stop funding them.
Frequently asked questions
Why should I track lead source to revenue, not just to lead?
Because a source can produce many cheap leads that never close. Only by following source through to closed revenue do you see true cost per acquisition and know which channels actually fund the business versus inflate your lead count.
What is first-touch versus last-touch attribution?
First-touch credits the source that originally created the lead; last-touch credits the source of the final interaction before conversion. Both are simplistic for multi-touch journeys, but tracking at least one consistently beats tracking none.
How do I stop "unknown" lead sources?
Make source a required, standardized field captured automatically at creation from web parameters, integrations, and rep entry with a fixed picklist. Free-text and optional source fields are why so many leads end up unattributed.
