When someone fills in a form, books a demo or sends an enquiry, their interest is highest at that moment. Every hour that passes before they hear back, they may be talking to a competitor, getting distracted or losing the urgency that made them reach out. That is the idea behind speed to lead. It is one of the few sales and marketing principles backed by well-known research, and one of the easiest to improve with process and automation. This article summarises the research, explains how to measure response time properly and sets out the routing, automation and staffing changes that reduce it.
What the research found
The most cited research is an article titled The Short Life of Online Sales Leads by James Oldroyd, Kristina McElheran and David Elkington, published in Harvard Business Review in March 2011. It reported an audit of 2,241 US companies, measuring how long each took to respond to a web-generated test lead. According to the article, 37 per cent responded within an hour, 16 per cent within one to 24 hours, 24 per cent took more than 24 hours and 23 per cent never responded. Among those that responded within 30 days, the average response time was 42 hours. Separately, the authors analysed a large set of sales leads from US companies and reported that firms that tried to contact a lead within an hour were nearly seven times as likely to qualify it as those that tried even an hour later, and more than 60 times as likely as those that waited 24 hours or longer.
How to read the research today
The research is old, comes from the US and measured qualification rather than revenue, so treat the exact multiples with care. The direction of the finding is the useful part: interest decays quickly after an enquiry, and fast responses tend to convert better than slow ones. In markets where buyers contact several suppliers at once, such as many Indian B2B and services categories where enquiries go to multiple vendors through marketplaces and directories, the first credible response often has an advantage. Your own data is the best guide: measure conversion by response time bands for your leads and see how steeply it falls.
Measure response time properly
Define response time as the time from the lead being created to the first meaningful contact attempt by a person, such as a call, a personalised email or a WhatsApp message, not an automated acknowledgement. Record both timestamps in the CRM. Report the median and the share of leads contacted within your target window, broken down by source, rep, time of day and day of week. Averages are distorted by a few leads that wait days, so medians and percentages within target are more useful. Many teams discover that response is fast in the morning and slow in the afternoon, or fast for website leads and slow for marketplace leads.
Response time targets by lead type
Set targets by lead type rather than one figure for everything.
| Lead type | Suggested response | Notes |
|---|---|---|
| Demo or callback request | As fast as possible in working hours | Highest intent; route instantly to an available rep |
| Pricing or quote enquiry | Same working hours | Often comparing suppliers; first credible reply matters |
| Marketplace or directory enquiry | Same working hours | Usually sent to several vendors at once |
| Content download | Within a working day, often by nurture | Lower intent; qualify before calling |
| Event or webinar registrant | Follow up after the event, by engagement | Prioritise attendees who asked questions |
Targets depend on your team size and lead volume. Measure your own conversion by response band before fixing numbers.
Routing and automation that cut response time
Most slow responses come from process, not effort. Route leads automatically to the right rep the moment they are created, by territory, segment or round robin, rather than leaving them in a shared inbox for someone to assign. Notify the rep immediately by the channel they actually watch, such as a mobile app alert, WhatsApp or a team chat. Send an instant automated acknowledgement that confirms the enquiry and offers a booking link, so high-intent buyers can schedule themselves. Use a lead queue that shows uncontacted leads in order of age, and reassign leads automatically if they are not contacted within the target window. The HubSpot round robin and Zoho lead assignment articles on this site cover the setup.
Outside working hours
Many enquiries arrive in the evening or at weekends. Options include an automated reply with a booking link for the next working day, a chatbot or WhatsApp flow that answers common questions and collects qualification details, a rota for urgent high-value enquiries, and a first-thing-tomorrow queue that reps clear before anything else. Be honest in the automated message about when someone will respond, and make sure the next-morning follow-up actually happens.
Quality still matters
Speed helps only if the response is useful. A rushed call from someone who has not read the enquiry can do more harm than a slightly slower, informed one. Give reps the context they need in the notification: what the person asked for, the page or campaign they came from and any qualification details. Use a short call script for first contact that confirms the need and books a proper conversation. And keep trying: one attempt is rarely enough. A structured sequence of calls, emails and messages over the following days usually reaches far more leads than a single fast attempt.
Estimating the value of faster response
To make the case for routing changes or extra staffing, estimate what slow response costs. Take your leads for a recent period, group them by response time, and compare the share in each group that became qualified opportunities. Multiply the difference in conversion by your opportunity value and win rate to estimate the revenue lost to slow responses. The lead routing delay cost calculator on this site does this calculation from a few inputs.
Making fast response a habit
Process changes hold only if they are reinforced. Put the share of leads contacted within target on the weekly sales dashboard, alongside pipeline and bookings, so it is reviewed as routinely as results. Look at it by rep privately and by team publicly, and treat persistent misses as a process question first: is the rep overloaded, receiving leads at times they cannot respond, or getting notifications they do not see? Agree what happens to leads that are not contacted within the window, such as automatic reassignment, so that no enquiry waits on one person. Revisit targets as lead volume grows, because a team that responds quickly at one volume may slow down at a higher one, and the cost of slow response rises with every additional lead that waits.

Speed to lead for marketplace and directory enquiries
In India, many B2B and services businesses receive enquiries from marketplaces and directories, where the same buyer request often goes to several suppliers at once. Response speed matters even more here, because the buyer may choose whichever credible supplier calls first. Integrate these sources with the CRM where possible, so enquiries arrive with a source tag and trigger the same routing and alerts as website leads, rather than sitting in a portal inbox. Track response time and conversion for these leads separately, since their quality and buyer behaviour differ from leads who found you directly. The IndiaMART and Zoho CRM article on this site covers one way to connect a marketplace to the CRM.
FAQ
The time between someone submitting an enquiry and the first meaningful response from a person, such as a call or personalised message.
A 2011 Harvard Business Review article reported that firms contacting leads within an hour were nearly seven times as likely to qualify them as firms that waited even an hour longer.
From lead creation to the first contact attempt by a person, recorded in the CRM, reported as a median and as the share within target, by source and rep.
Not for speed-to-lead measurement. Automated acknowledgements help, especially with a booking link, but measure the first contact by a person separately.
Use an honest automated reply with a booking link, a chatbot or WhatsApp flow for questions, and a next-morning queue that reps clear first.
Often, because the same request is usually sent to several suppliers. Route them into the CRM with alerts and track their response time and conversion separately.
