Lead Response Time (LRT)

Lead response time is the operations metric behind the sales phrase speed to lead. It is measured per lead, in seconds or minutes, from the timestamp of the first form, chat, DM or call to the timestamp of the first reply that addresses what the person asked. Auto-acknowledgements do not count. Once an AI agent is on the channel the first-response number collapses, and LRT splits into two metrics: time to first substantive reply (the agent) and time to first human contact for the leads that need one.

How it works. Every inbound channel produces a start event: a form webhook, a WhatsApp message, a chat widget opening, a ring on the inbound line. The agent's first answer produces the end event. Both are logged with channel, hour of day and weekday. For leads the agent routes to a person, a second end event is the moment a human replies or dials. Report the median and the 90th percentile, split by channel and by in-hours versus after-hours. The 90th percentile is the honest number because it shows the leads that waited longest, which are usually the evening and weekend ones.

Why it matters for sales teams. A prospect who asks a question is comparing options at that moment. A reply the next morning arrives after the comparison is over. Slow LRT also hides inside averages: a team that replies in two minutes during the day and twelve hours at night reports a reasonable mean and loses most of its evening leads. Measuring by hour exposes the gap and shows which hours to automate first.

Example. A real-estate brokerage tracks LRT on listing inquiries from its website and Instagram. Before automation, the median is four minutes in office hours and nine hours overnight. After putting a chat agent on both channels, first substantive reply is under ten seconds at any hour; the agent answers the listing question, asks buy-or-rent and budget, and books a viewing or routes the lead to the listing agent. The brokerage now reports time to human contact for routed leads, with a one-hour target during the day, and viewing bookings by hour of first contact.

Lead response time vs sales velocity. LRT measures the first step only: how long the prospect waited for a reply. Sales velocity measures the whole pipeline: how much revenue moves through it per day given deal count, value, win rate and cycle length. Improving LRT raises the top of the funnel and shortens the first stage; it does not by itself change win rate or deal size.
