Diversifying your line of products and services around a common theme. Even if you happen to stumble across one of those relatively rare items that is enormously successful on its own, you can still benefit by diversifying and expanding your product line. When you offer a variety of related products and services, prospects are more likely to find something they want to buy.
Diversity increases the average order amount.
Offering prospects and customers a variety of things to purchase from you also makes it more likely they'll purchase multiple items, thereby increasing the average amount of profit per order. Some marketers find it better to initially focus on making one sale without any other offers that might confuse a prospect, and following up with related offers at a later time. Diversity helps you take maximum advantage of the lifetime value or your customers. Many marketers are content to sell one thing to a customer, one time, and forget about that customer forever, only to continue their quest for new customers elsewhere. However, such a strategy overlooks lucrative profits available through additional sales to existing customers.
