The most cited study is Harvard Business Review's 2011 analysis of 1.25 million leads: firms that tried to contact a lead within an hour were nearly seven times as likely to qualify it as firms that tried an hour later, and more than 60 times as likely as firms that waited 24 hours or longer. Yelp, Thumbtack and Google publish their own versions of the rule.
TL;DR
- HBR audited 2,241 US companies: 37% replied within an hour, 23% never replied.
- Contact within an hour: nearly 7x as likely to qualify the lead; 60x+ versus waiting 24 hours or longer.
- Yelp: under a day means 4x more requests (2017 internal data); an hour plus a specific reply means customers are 2x more likely to respond.
- Thumbtack and Google both say response speed affects ranking; neither publishes a 5-minute rule.
What did the Harvard Business Review study find?
In “The Short Life of Online Sales Leads” (March 2011), James Oldroyd, Kristina McElheran and David Elkington ran two studies (Harvard Business Review).
First, they audited 2,241 US companies, measuring how long each took to respond to a web-generated test lead. Of those, 37% responded within an hour and 16% within one to 24 hours; 24% took more than 24 hours, and 23% never responded at all. Among companies that responded within 30 days, the average response time was 42 hours.
Second, they analyzed 1.25 million sales leads received by 29 B2C and 13 B2B companies. Firms that tried to contact potential customers within an hour of receiving a query were nearly seven times as likely to qualify the lead 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.
What do Yelp, Thumbtack and Google say about reply speed?
| Source | What they say |
|---|---|
| Yelp, help center | “Businesses with a response time of less than a day see 4x more requests than businesses who wait longer to reply.” Footnoted as Yelp internal data, 2017. |
| Yelp, 2025 guide | Customers are 2x more likely to respond when a pro replies within an hour and addresses project details and questions; your response time is shown publicly on your Yelp page. |
| Thumbtack, help center | “You’re more likely to get hired when you’re quick to respond,” and your response rate “affects your rank in search results.” Aim for four hours; Pro Rewards Gold and Platinum need replies within one hour 65% and 75% of the time. |
| Google Local Services Ads | Ranking factors include “your responsiveness to customer inquiries and requests” (missed calls may hurt it) and profile quality, which includes average response time. |
| Google Local Services Ads | “For message leads, your average response time may be displayed in your ad, and quick response times can drive greater consumer engagement on your ad.” |

See how it worksWhat does the research not tell you?
It is worth being precise, because a lot of speed-to-lead content is not.
- It is from 2011 and it is not about home services. The HBR data came from B2C and B2B companies in general, before today’s lead marketplaces.
- “Qualify” is not “book”. HBR measured whether a lead was qualified, not whether a job was sold.
- Platform figures are the platforms’ own. Yelp’s 4x is footnoted as 2017 internal data, and the 2x figure comes from a guide, so treat both as directional.
- None of these sources gives a 5-minute rule. The thresholds they actually publish are one hour (HBR, Yelp’s 2x, Thumbtack Pro Rewards), four hours (Thumbtack’s general guidance) and one day (Yelp’s 4x).
How should a home service business apply this?
- Measure your own median. Yelp already shows yours (how Yelp calculates it); for Thumbtack, check the response rate in your Performance dashboard (what Thumbtack counts).
- Cover nights and weekends. Google’s own advice on message leads is aimed at the moments you cannot answer the phone.
- Make the first reply useful. Speed only helps if the message answers the request. Yelp’s guide says the 2x effect comes with addressing the project details, not just suggesting a call.
- Do not let leads die unanswered. HBR found 23% of companies never replied at all; on Yelp, long silence can switch messaging off. The six places leads go cold show where they usually die.
- Put a number on it. Run your figures through the lost-revenue calculator for a rough estimate for your business.
FAQ
How fast should you respond to a lead?
Within an hour, based on the published evidence: HBR found firms that tried to contact leads within an hour were nearly seven times as likely to qualify them, and Yelp and Thumbtack both use one hour in their published guidance (with a general Thumbtack target of four hours and a Yelp benchmark of one day). Faster is safer when a customer is comparing several pros.
Is there a study behind the “5-minute rule”?
None of the sources in this article publish a 5-minute threshold. HBR, Yelp and Thumbtack use one hour; Thumbtack also uses four hours and Yelp one day.
What share of companies never respond to leads?
In HBR’s audit of 2,241 US companies, 23% never responded to the test lead.
Does response time affect Google Local Services Ads ranking?
Google lists responsiveness to customer inquiries as a ranking factor, notes that missed calls may hurt it, and includes average response time in profile quality.
