Speed to Lead: What the Research Found and How to Measure Yours

Speed to lead is the time between a lead asking to hear from you (a form, an ad lead, a missed call) and your first real response. The best-known research found that firms that tried to reach a web lead within an hour were nearly seven times as likely to have a real conversation with a decision maker as firms that waited even an hour longer (Harvard Business Review, 2011). In the same article's audit of 2,241 companies, only 37% answered a test lead within an hour.

What the research actually found

Study	Sample	Finding	Limits
Lead Response Management study, Oldroyd and InsideSales.com, 2007	3 years of data, 6 companies, 15,000+ leads, 100,000+ call attempts	Odds of contacting a lead drop 100 times at 30 minutes vs 5; odds of qualifying drop 21 times	Phone dials only, one vendor's data, did not measure closed sales
"The Short Life of Online Sales Leads", HBR, 2011	Audit of 2,241 US companies; separate analysis of 1.25 million leads at 42 companies	37% answered a test lead within an hour, 23% never answered; average 42 hours. Contact within an hour: nearly 7 times as likely to qualify	Data collected before 2011; co-author ran the vendor that supplied it
InsideSales lead response research, 2021	5.7 million inbound leads, 55 million sales tasks, 400+ companies, 3 years	Conversion 8 times higher when the first attempt came within 5 minutes vs 6 or more	Vendor blog, no published method
Mike DelPrete, 2024	100+ secret shops at 25+ real estate brokerages	47% of online property inquiries ignored; median reply 39 minutes, average 8 hours 17 minutes	Small sample; weekday business hours only

The 2007 Lead Response Management study (the "5 minutes" study)

The study's exact wording: "The odds of contacting a lead if called in 5 minutes versus 30 minutes drop 100 times. The odds of qualifying a lead if called in 5 minutes versus 30 minutes drop 21 times." It also found the odds of contact fall 5 times between minute 5 and minute 10 (LRM report, MarketingSherpa summit, October 2007).

Limits, from the same report: the data came from InsideSales.com's own system, covered six companies, counted phone dials only, and "did not address close ratios." Each company defined "qualified" its own way. It was presented at a marketing conference, not published in a journal. It is often credited to MIT or Harvard; Oldroyd was a faculty fellow at MIT at the time, but it is a vendor study.

The 2011 Harvard Business Review article

James Oldroyd, Kristina McElheran and David Elkington ran two separate studies. First, they "audited 2,241 U.S. companies, measuring how long each took to respond to a web-generated test lead." Second, using 1.25 million leads at 29 B2C and 13 B2B companies, firms that tried to contact a lead within an hour "were nearly seven times as likely to qualify the lead (which we defined as having a meaningful conversation with a key decision maker) as those that tried to contact the customer even an hour later, and more than 60 times as likely as companies that waited 24 hours or longer" (HBR, March 2011).

The 42-hour average counts only companies that responded within 30 days, and "qualify" means a conversation, not a sale. Elkington was CEO of InsideSales.com, which sold lead response software.

What the studies can't tell you

All of these are observational. Teams that respond fast may also be better at everything else, so the seven-times and 100-times figures are not what you will get by speeding up. None of them tested a text message as the first touch, so treat a first text as an attempt and measure first contact separately. The direction is consistent across 2007, 2011 and 2021 data; the size of the effect in your business is something you measure yourself.

Speed to lead in real estate

In Mike DelPrete's 2024 secret shops of real estate brokerage websites, 47% of online property inquiries got no response, and every inquiry was sent during weekday business hours (DelPrete, 2024). The same shops found 62% of open house visitors got no follow-up at all.

Buyers rarely shop around for an agent: 77% of repeat buyers and 67% of first-time buyers interviewed only one agent, and 81% of sellers contacted only one (NAR 2024 Profile of Home Buyers and Sellers). Many of those buyers came by referral, so this doesn't prove the fastest agent wins. It does mean the agent who talks with a buyer first often never faces a comparison.

How to measure your own speed to lead

Record three timestamps per lead. The 2007 study used the same split: lead created, first dial attempt, first contact (LRM report).

1. Lead created: when the person submitted the form or called, not when the lead reached your CRM. Use the submit time the form, ad platform or phone system records, so every source is measured from the same moment.
2. First attempt: the first call or text to the lead, whether a person or software sent it. An automatic "thanks, we got your request" email does not count.
3. First contact: the first two-way exchange, a call answered or a text reply.

Speed to lead is first attempt minus lead created. Report the median, not the average. One overnight or weekend lead drags the average up and hides what usually happens. Ten example leads, answered after 2, 3, 4, 6, 8, 12, 25, 40, 610 and 1,450 minutes:

Measure	Result	What it tells you
Average	216 minutes (3.6 hours)	Little; two leads set it
Median	10 minutes	A typical lead's wait
Answered within 5 minutes	3 of 10	How often you hit the target
Waited over 1 hour	2 of 10	Your failures; find out why each one waited

Clock hours, not business hours. A lead sent Friday at 7 PM and answered Monday at 9 AM waited 62 hours, even if a business-hours report says zero. Report clock time as your number. Use business hours only to see whether the problem is staffing (slow during the day) or coverage (slow at night and weekends). Leads that arrive when you can't legally text or call still count from submit time; report them as their own group so the overnight wait doesn't hide inside the daytime median.

Then split the median by lead source, by rep and by hour of day. A slow source usually points to the integration; a slow hour means nobody covers it.

Getting the data. Most CRMs keep a created date on each lead and a log of calls and texts. Export both, find each lead's earliest outbound activity, and subtract. A spreadsheet is enough for the first month.

What to aim for. A median under 5 minutes during staffed hours matches the window in the 2007 study. If you work leads by hand, start with every lead answered inside an hour, the HBR threshold, and no lead waiting overnight without a reply.

How to get it down

• Send leads in real time. HBR named retrieving leads from CRM databases "daily rather than continuously" as a main cause of slow response (HBR, 2011). Connect every source by webhook or native integration; drop daily CSV imports and email forwarding.
• Fix routing rules. The same article blamed distributing leads by "geography and fairness." In the 2007 survey of 495 companies, skills-based and first-available routing were linked to higher qualification rates; a drop for geographic routing fell just short of significance (LRM report).
• Round robin with a timeout. Assign each lead to the next available rep, and if nobody calls or texts within 5 minutes, reassign it or open it to the whole team.
• Alert by push or text, not email. Send the rep the lead's name, source and what they asked about, with a tap-to-call link. Alert a manager when a lead passes 15 minutes untouched.
• Send an automatic first text. It goes out in seconds while a person gets ready to call, and it gives the lead a way to reply. Your number needs an approved texting registration first; see A2P 10DLC registration.
• Get consent on the form. Federal rules require prior express written consent for marketing messages sent with an autodialer: a written agreement signed by the lead that authorizes messages to that number and says agreeing is not a condition of purchase (47 CFR 64.1200(f)). Put a consent line with a checkbox next to the phone field.
• Cover nights and weekends. Use an on-call rotation or automated texting. Federal rules bar telephone solicitations before 8 AM or after 9 PM at the called person's location (47 CFR 64.1200(c)), and Florida's limit for commercial solicitation calls is 8 PM (Florida Statutes section 501.616). Queue late leads for the next morning and reach them first.
• Keep following up. In InsideSales' 2021 data, only 23% of inbound leads ever got a single attempt from a rep, and 7 or more attempts raised connection rates by 15% (InsideSales, 2021).

First texts you can copy

Illustrative examples: each names the sender, mentions what the lead asked about, and asks one easy question.

• Home inquiry: "Hi Dana, it's Sam with Acme Realty. You asked about 412 Oak St. It's still available. Want to see it this week, or just starting to look?"
• Quote request: "Hi Marcus, this is Jen at Northside Insurance. Got your auto quote request. Is the policy for just you, or anyone else in the house?"
• Mortgage lead: "Hi Priya, Alex from Summit Lending. Thanks for asking about a home loan. Are you buying a home or asking about the loan you have now?"
• Late-night lead, next morning: "Morning Chris, it's Sam with Acme Realty. Saw your message from last night about the Pine Ave condo. Good time for a quick call today?"

If you use Out Nurture

Out Nurture sends each new lead a first text within seconds during texting hours, which are 8 AM to 9 PM in the lead's time zone, every day. Leads that arrive at night get their first text after 8 AM. It carries the conversation, decides when to follow up, and hands ready leads to your salesperson by group text or email summary. Leads come in by webhook, API or CSV, and it files your texting registration from inside the app.
