What does research say about lead follow-up and reminders?
Fast replies and simple reminders are among the best-supported habits in lead handling. Below are plain-English summaries of four published studies, what they found, where they fall short, and what to do with them. We did not run these studies; each one links to its source.

1. Answer web leads within the hour
Oldroyd, McElheran & Elkington, “The Short Life of Online Sales Leads”, Harvard Business Review, March 2011 · alternative link
What it found
- An audit of 2,241 US companies found that 23% never responded to a web-generated test lead (Harvard Business Review, 2011). Among those that did respond within 30 days, the average response time was 42 hours.
- A separate analysis of 1.25 million leads found that firms that tried to contact a lead within an hour were nearly seven times as likely to qualify it (have a meaningful conversation with a decision maker) as firms that waited even an hour longer.
Limits
The data is from US companies around 2010 and measures qualification, not closed sales. Buyer behaviour and channels have changed since.
What to do
Set a target to reply to every new lead within minutes during business hours, and send an automatic text or email reply outside them. How to respond to leads faster
2. Text reminders improve appointment attendance
Gurol-Urganci et al., “Mobile phone messaging reminders for attendance at healthcare appointments”, Cochrane Database of Systematic Reviews, 2013 · alternative link
What it found
- Across 7 trials (5,841 participants), text reminders improved attendance compared with no reminders (risk ratio 1.14, 95% CI 1.03–1.26; moderate-quality evidence; Cochrane review, 2013).
- Text reminders worked about as well as phone-call reminders (3 trials, 2,509 participants), and two studies found them cheaper per attended appointment.
Limits
The trials were in healthcare settings. Results in other service businesses may differ, and the review notes the need for more high-quality trials.
What to do
Send an automatic confirmation when someone books and a reminder before the appointment, with an easy way to reschedule. How to reduce appointment no-shows
3. Slow pages lose visitors
Google / SOASTA research, 2017, published on Think with Google
What it found
- The probability of a visitor bouncing increases 32% as mobile page load time goes from 1 second to 3 seconds (Think with Google, 2017).
Limits
This is a 2017 statistic about bounce, not leads or sales, and Google has not published the full method on that page.
What to do

4. Interruptions cost stress, not just time
Mark, Gudith & Klocke, “The Cost of Interrupted Work: More Speed and Stress”, CHI 2008
What it found
- In a lab experiment, people who were interrupted finished tasks in less time with no loss in quality, but reported more stress, frustration, time pressure and effort.
Limits
A lab study of email tasks, not a study of CRM use. It supports reducing context switching; it does not measure revenue.
What to do
Keep leads, messages and bookings in as few tools as possible, so staff aren't switching between apps to answer one customer. How to set up a small business CRM
