The two studies behind the numbers

Both are about internet leads, the inquiries people send through a website. Here’s what each report says about itself.

Chapter 02Fact-check

Where “21x” really comes from

Not a Harvard figure

The 21x comes from the 2007 LRM study, built on InsideSales.com data. That report never mentions Harvard. HBR’s 2011 article shares two of its authors.

The study cut the first 3 hours after a form was sent into 5-minute blocks. Qualifying odds were 21 times higher when the call came within 5 minutes than at 30.

10x in the first hourSource: LRM study, 2007What it measured: Odds of contact over the first hour (qualifying: over 6x)

Checked against the 2007 report. A dash means the figure isn’t in it; we couldn’t search HBR’s full text.

One caution: the report gives odds, not the rates behind them. So you can’t turn “21x” into a count of extra qualified leads.

Chapter 03HBR 2011

What you can check in HBR 2011

The Short Life of Online Sales Leads ran in Harvard Business Review in March 2011. Its authors: James B. Oldroyd, Kristina McElheran and David Elkington. HBR lists Elkington as InsideSales.com’s chairman and CEO.

Are you confident that your company is effectively handling potential customers’ online queries? Think hard. Our research shows that most companies are not responding nearly fast enough.

The rest is behind HBR’s paywall. So we don’t repeat its sample, method or figures here.

Chapter 04Caution

What doesn’t carry over to DMs

The 2007 study timed phone calls to web-form leads. A DM works differently, so treat its multiples as a direction, not a forecast.

  • Contact meant a live call

    The 100x measured reaching a person by phone. A DM thread is already open.

  • A reply can wait

    A call needs the lead free to pick up. A DM waits until it’s read.

  • Old data, other buyers

    Six companies’ leads, about two decades old. Not your audience or your offer.

  • Each app sets rules

    Instagram, WhatsApp and Messenger each limit when a business can message.

The 2007 report guessed why speed mattered: the lead is still near the phone, and interest and need wane quickly. Neither was tested in DMs, so measure your own. For the messaging windows, see Instagram DM limits.

Chapter 05Your data

Measure your own response time

In Oldroyd’s 2007 survey, 38% of 495 companies didn’t know, didn’t measure or didn’t say how long a first call attempt took. Here’s how to know yours in DMs.

Then change one thing, like who answers at night, and compare the same numbers a few weeks later.
