Most of my credit cards are of the “no annual fees” type, including one MasterCard on a separate account I keep at home as a spare in case I lose my wallet or incur any fraudulent charges. However, I do use a main Visa card which does have an annual fee because all purchases on that card reward me with airline frequent flyer points. For me, the annual fee is worth it since I do travel and I get enough points to redeem many free flights.
ShareASale offers pay-per-sale, pay-per-lead, and pay-per-click programs, with a minimum payout of $50. ShareASale is my favorite affiliate program network because of their large marketplace (they have tons of blogger-friendly affiliate programs) and the ease of use. If you want to make money through affiliate marketing, I highly recommend you give ShareASale a try.
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. You'll need an audience to train and you'll need to know what you're talking about. Of course, this usually requires having a website and some semblance of an online presence. However, people can still do webinars without all of that. For example, you might have a sizable social media following and you train them every week on something to do with social media. But you will need a product to embed and sell at some point. Don't worry about it in the beginning. In my experience, the best webinar platform out there is GoToWebinar.
Ratings. Whenever someone buys a book from you, they will have the opportunity to give the transaction a rating. This is when they’ll tell other potential buyers whether the book was in the condition that you described, whether it was mailed on time, and if your communications were pleasant and helpful. One bad rating can hamper sales, and a couple of them can downright stop them. Excel at customer service and your ratings will help your company grow.
If you have a background in marketing and a passion for a particular niche, then organizing a virtual event may be just up your street. A virtual event could span across a day or longer. Individual live sessions would be run by experts in the field. And conference features would include live question and answer sessions, forums, and plenty of free giveaways. Visitors to the virtual event would pay to attend, so the more effective your promotion of the event the more money you would make.
