10 ways to... Promote a new offer
No matter how good your new product or service is, it won't do as well as you deserve unless you promote it properly. Try these road-tested techniques.
Your key customers are the most likely to buy your new offer, so make them feel valued. Arrange one-to-one meetings to tell them about the benefits in advance of the main launch.
Make your customers work for you. Offer them a reward, such as a discount on their own order, for introducing a new contact to the new product or service.
Use established products or services as door-openers. Give away taster sessions, free samples or discount vouchers when you make a sale of an existing product.
Introduce a special introductory price or a two-for-one offer. Always check your margins and the duration of the offer before you announce a promotional price; do not leave yourself committed to a loss-maker.
Create point-of-sale material that list the benefits of the new offer
