Every lead you pay for, from an ad, your website or a directory, is a person who is probably filling in two or three other forms too. "Speed to lead" is how fast you get back to them. This lesson answers one question: how fast should a small business reply? It takes a short, honest look at the study everyone quotes, then turns it into a response-time standard you can run without a sales team. For the full set of speed to lead statistics and where each one comes from, see our blog post.
The study everyone quotes
In March 2011, Harvard Business Review published "The Short Life of Online Sales Leads" by James B. Oldroyd, Kristina McElheran and David Elkington. Most speed-to-lead claims online trace back to it. Few link to it, and plenty misquote it.
The article sits behind HBR's paywall. The figures below come from a July 2011 SmartCompany summary that quotes the study directly. We couldn't check them against the full text.
Part 1: an audit of response times. The authors audited 2,241 US companies on how quickly they responded to web leads:
| Response | Share of companies |
|---|---|
| Within an hour | 37% |
| Within 1-24 hours | 16% |
| More than 24 hours | 24% |
| Never responded | 23% |
Among companies that responded within 30 days, the average response time was 42 hours, almost two days.
Part 2: response time and results. The authors analyzed 1.25 million sales leads received by 42 US companies (29 business-to-consumer, 13 business-to-business). Companies that tried to contact a lead within an hour were:
- nearly seven times as likely to qualify the lead as those that tried an hour later; and
- more than 60 times as likely as companies that waited 24 hours or longer.
"Qualify" here meant "having a meaningful conversation with a key decision maker", not winning the sale.
What the study does and doesn't tell you
The finding is striking, and it makes sense. Before you build your business around "7x", though, look at the limits:
- It's old. The data predates widespread business texting, WhatsApp, online booking and chat widgets. Customer expectations have probably moved since. The study can't say how far.
- It measured "qualifying", not sales or revenue. A conversation with a decision-maker is one step toward a booked job.
- It's correlation, not proof of cause. Companies that respond fast may also be better run in other ways, with better staff or better offers. Fast responders did better in the study. It can't prove speed alone was the reason.
- It's not about local trades. The companies came from many industries and included B2B firms. A homeowner with a burst pipe doesn't shop like a software buyer.
- One author came from industry. Brigham Young University's record of the article lists David Elkington's affiliation as Inside Sales; he founded InsideSales.com, a company in the inside-sales industry. That doesn't make the findings wrong, but it's worth knowing.
A fair reading: in this study, replying within the first hour went hand in hand with much better outcomes, and lots of companies were slow. That's reason enough to be fast. Just don't treat "7x" as a promise.
A note on vendor statistics
Search "speed to lead" and you'll find claims like "respond in 5 minutes for 21x more conversions" or "78% of customers buy from the first business to respond". Before you repeat one, ask three questions:
- Who ran it? Most come from companies selling lead response, call tracking or AI chat software. That's vendor data, which can be useful but is never neutral.
- Can you find the original? Many figures are copied between blogs with no link to a method. If you can't find the method, don't rely on it.
- What did it measure? Contact rate, qualification and purchase are different things.
One vendor figure that is at least traceable: Clio, a legal software company, ran secret-shopper calls to law firms for its 2024 Legal Trends Report. The American Bar Association's Law Practice Magazine reports it found "only 40 percent of law firms answered phone calls—a decline from 56 percent in 2019." Again, that's vendor data, and it covers law firms only.
A local example: the HVAC company on a hot Saturday
An HVAC company runs Google and Meta ads. It's a hot Saturday in July. At 10:12 a.m. a homeowner fills in a web form: "AC blowing warm air, 2-year-old system." She also fills in forms for two competitors.
- Competitor 1 replies Monday morning by email.
- Competitor 2 has a form that sends an automatic "we got your request" email, then calls at 2 p.m.
- Our company has the form send a text within a minute: "Hi Sarah, this is Cool Air. We got your request about your AC. A technician can call you in the next 15 minutes. Is this a good number?" The on-call tech gets an alert and calls at 10:25.
Nothing guarantees Sarah books with them. But they're the only one who reached her while she was still holding her phone and sweating in a hot living room.
Setting your own standard
Start with targets your current team can actually hit. Tighten them later.
| Lead type | Suggested first-reply target | How |
|---|---|---|
| Phone call during hours | Answer live | Ring group or answering service |
| Missed call | Text within 1 minute, call back within 15 | See Missed calls |
| Web form or ad lead form | Acknowledge within 5 minutes; human contact within 1 hour | Instant text or email plus staff alert |
| Text or WhatsApp message | Reply within 15 minutes in hours | Shared inbox on staff phones |
| After hours | Instant acknowledgement with when you'll reply | Auto-reply, then first thing next morning |
These are our suggestions, not research findings. What matters is that the first reply is instant and honest ("we got it, a person will call by X"), and that a human follows up inside the time you promised.
What makes the first reply work
- Use their name and what they asked about. "We got your request about your AC" beats "Thank you for your inquiry."
- Give a time and a person. "Mike will call you within 15 minutes."
- Ask one easy question so they can reply in a word ("Is this the best number?").
- Use the channel they used, or the one they prefer. Texting someone requires their consent in the US; see Texting customers in the US.
- Then actually call. An automated text buys time; it doesn't replace a person.
Measure it
If you don't track it, you're guessing. Once a week, pull last week's leads and write down:
- time the lead arrived;
- time of first reply (automatic);
- time of first human contact;
- whether it became a booked job.
After a month you'll know your real median response time, and whether faster replies are booking more jobs for you. That beats every statistic in this lesson.
Do this now
What is speed to lead?
The time between a potential customer contacting you (form, call, message) and your first meaningful reply. Faster replies reach people while they're still deciding.
What did the HBR lead response study find?
In a 2011 HBR article, companies that tried to contact leads within an hour were nearly seven times as likely to qualify the lead as those that waited an hour longer, and more than 60 times as likely as those that waited 24 hours or more.
Is the "respond in 5 minutes" rule proven?
Not in the HBR article, which looked at the first hour. Five-minute claims usually come from vendor studies. Fast is good; check the source before quoting a number.
Does an automatic reply count?
It helps by acknowledging the lead instantly, but follow it with a real person within the time you promise.
