How quickly should businesses respond to internet leads?
Businesses should respond to internet leads within 5 minutes — and ideally within 60 seconds. Research published by InsideSales.com (the MIT lead response study) found that contacting a lead within 5 minutes makes you up to 100x more likely to connect and 21x more likely to qualify the lead than waiting just 30 minutes. Yet the average company takes about 42 hours to respond, according to a Harvard Business Review audit of 2,241 U.S. companies.
Key facts
- 5 minutes vs. 30 minutes: 21x more likely to qualify the lead; up to 100x more likely to make contact (InsideSales.com / MIT lead response study).
- Only 37% of companies respond to leads within one hour; the average response time is 42 hours (Harvard Business Review, 'The Short Life of Online Sales Leads').
- 78% of customers buy from the first business to respond (Lead Connect).
- After 5 minutes, the odds of qualifying a lead drop roughly 80% (Vendasta / InsideSales analysis).
Why the first 5 minutes decide the sale
An internet lead is a person actively shopping right now — usually with multiple browser tabs open. Within minutes they have contacted 2–3 competitors. The first business to respond frames the conversation, books the appointment, and usually wins the job: 78% of customers buy from the first responder.
What response times look like in reality
The Harvard Business Review audit found the average company takes 42 hours to respond to a web lead, 23% never respond at all, and only 37% respond within the first hour. For local service businesses the numbers are worse after hours — nights and weekends account for a large share of inquiries and almost none get a same-hour reply.
How to actually respond in under a minute
No human team reliably answers in 60 seconds around the clock, so fast responders automate the first touch: an instant SMS and email acknowledging the inquiry, qualifying questions handled by AI, and calendar booking offered immediately. A human then takes over during business hours with the lead already engaged and scheduled.
The cost of being slow
If a business pays $75 per lead from Google Ads and responds in 4+ hours, a large share of that spend buys conversations with people who already booked elsewhere. Fixing response time is usually the highest-ROI change a lead-driven business can make — it improves conversion on every lead source at once without increasing ad spend.
