# What is lead response time (and why seconds matter)?

> Lead response time is how long it takes to contact a new enquiry after it arrives. Speed decides the outcome: a Harvard Business Review study of 2,241 US companies found that firms contacting leads within an hour were nearly seven times as likely to qualify them as firms that waited longer, and more than 60 times as likely as those that waited 24 hours or more.

## Why AI calling changes this

A human telecaller calls back in hours and one lead at a time. An AI caller rings every new lead within seconds, in parallel, so no lead waits. This is the single biggest reason Indian SMBs adopt outbound voice agents.

## What the research measured

The study, [The Short Life of Online Sales Leads](https://hbr.org/2011/03/the-short-life-of-online-sales-leads) (HBR, 2011), defined qualifying a lead as having a meaningful conversation with a decision maker. The average company that responded at all took 42 hours. The lesson for an Indian business with Meta or website leads is the same: the first caller usually wins.

## Frequently asked questions

### What is a good lead response time?

As fast as you can make it. Within five minutes is a common target for sales teams; an AI caller can ring within seconds of the lead arriving, day or night.

### How do I measure my current lead response time?

Compare the time each lead arrived with the time of the first call attempt, across a few weeks of leads. Use the median, not the average, so one lead called a week later does not hide the typical delay.
