In the field of Internet Marketing, OTO is an acronym, which means “One Time Only”. The intention of OTO offers is to up-sell the customer, and to get them to buy another item related to the item they already intend to buy.
When a customer approaches your online business site, they have to decide whether to take action immediately regarding the product they intend to buy. In many cases, these offers must be declined in order to get back to the previous page. These OTO offers frequently encourage the customer to take action now.
For example, if the potential customer of your car mechanic’s shop needs a tune-up, they may hesitate to schedule an appointment. However, if they see an OTO pop-up offering a $20 tune-up if they decide to schedule right now, it makes them more likely to set the appointment immediately.
