2) Lead conversion
The process by which you convert leads into paying customers. This is the measure of the effectiveness of your sales efforts. If you can increase your conversion rate from one out of ten to two out of ten, you can double your sales and increase profits.
Improving your ability to sell and convert interested prospects into paying customers is one of the most important things you can do. And there is no replacement for ongoing sales training, both for you and for every single person who speaks to customers, either live or on the phone.
Look at every key result area in your sales process and seek ways to improve a little bit in each area. A small improvement in each key area can lead to an enormous improvement in overall sales results.
