If you sell online and want to generate revenues here are a few recomendations:
1. Have a 50% off sale of damaged goods such as physical books, specialty items, training manuals, etc.
2. When you do an online promotional campaign, your sales will go up if you do a follow up message with FAQ's - Frequently asked questions that the buyers have regarding the purchase you are asking them to make. This is especially important in higher priced service offerings.
3. Offer a multi payment schedule for higher priced items.
4. Make your offer for a limited time and with a limited quantity.
5. Keep in touch after the purchase. This build trust between you and the buyer.
