How Does the Speed-to-Lead Calculator Work?

It starts with your current enquiries, conversion rate and customer value to show what you win now. It then compares that with faster-response scenarios: either your own fast-reply conversion rate from your CRM, or three labelled improvement scenarios of 10%, 25% and 50%.

Instant replies usually come from an AI chatbot on your website plus automated lead follow-up, and faster responses make paid search campaigns more profitable. Losing calls after hours?

We don’t apply a single “universal” figure, such as claims that replying in five minutes multiplies conversions by a fixed amount, because the real effect varies by industry, lead source and price point. The most reliable approach is to measure your own conversion by response time.

FAQs

Speed-to-Lead FAQs

What is speed to lead?
The time between an enquiry arriving and your first meaningful response.
What is a good response time?
An instant automated acknowledgement plus a personal reply within minutes during business hours is a practical target for most businesses.
Why doesn’t the calculator use a fixed industry statistic?
Published figures vary widely and often come from other countries or industries. Your own data is more reliable, so the calculator uses it where possible.
Does an automatic reply count as a response?
It reassures the enquirer, but a personal or genuinely useful reply usually matters more for conversion.
