It’s helpful to think about your lead generation in terms of “filling a funnel,” the funnel representing the information process you’re taking people through.
To use an analogy, if you poured a couple of drops of petrol into a funnel, and waited for them to come through the other end before you poured another couple of drops through, you may never end up with any coming through. Reason: the petrol may evaporate before it comes through. You need volume to avoid this problem.
Generating either warm or cold leads for your business is no different — you need sufficient volume coming through at any point in time so that you avoid “evaporation”.
