Inbound lead velocity (ILV)
Also known as: ILV
In short
Inbound lead velocity (ILV) is how quickly inbound leads progress through your funnel after they raise their hand. It is usually measured as elapsed time between steps, such as form fill to first contact, or lead to qualified opportunity.
ILV is a speed metric. It differs from lead velocity rate, which tracks month-over-month growth in qualified leads. ILV asks how fast; lead velocity rate asks how much more.
What ILV measures
There is no single standard formula, so pick the steps that match your process and define them clearly. Typical intervals are:
- Speed to lead:: Time from form submission to first outreach attempt.
- Speed to qualify:: Time from first contact to a qualified or rejected decision.
- Speed to meeting:: Time from inquiry to a booked first meeting.
- Speed to opportunity:: Time from inquiry to a created opportunity.
Why it matters
Inbound leads come from people actively researching, and interest fades as other vendors respond. Slow handling wastes the marketing spend that produced the lead. Measuring ILV makes handoff delays visible, such as leads sitting in a queue over a weekend.
How to measure and improve it
1. Timestamp every stage
Record created, assigned, first touch, and qualified dates in the CRM. Use the median, not just the average, since a few stale leads skew averages.
2. Segment the numbers
Compare by lead source, region, rep, and request type. A demo request should move faster than an ebook download.
3. Remove the delays
Automate routing, add round-robin or territory rules, alert owners, and book meetings directly from the form.
An example
Say demo requests have a median of 26 hours from form fill to first contact, because they wait for manual assignment. After adding automatic routing and an alert, the median drops to two hours. Compare meeting rates before and after to see if the speed change helped.
Common mistakes
- Measuring only the first touch and ignoring time to qualify.
- Counting an automated email as the first human contact.
- Chasing speed on low-quality leads instead of prioritizing high-intent ones.
Inbound lead velocity FAQs
What is inbound lead velocity (ILV)?
Inbound lead velocity is how quickly inbound leads move through your funnel after they show interest, measured as the time between steps such as form fill to first contact, or inquiry to qualified opportunity.
What is the difference between inbound lead velocity and lead velocity rate?
Inbound lead velocity measures speed, meaning how long leads take to move between stages. Lead velocity rate measures growth, meaning the month-over-month change in qualified leads. One tracks handling time, the other tracks pipeline momentum.
How do you measure inbound lead velocity?
Timestamp each stage in your CRM, such as created, assigned, first contact, and qualified. Calculate the elapsed time between stages, use the median to limit skew from outliers, and segment by source, rep, and request type.
How can you improve inbound lead velocity?
Route leads automatically with clear assignment rules, alert owners instantly, let high-intent visitors book meetings from the form, set a response SLA, and review stalled leads weekly. Prioritize demo requests over lower-intent content downloads.
