As a business model, dropshipping allows anyone to sell products from suppliers on their own website. There is no need to carry any inventory at all. When someone purchases a product from the dropshipper’s website, they place an order with the supplier. The supplier then packages and ships the product to the customer. Dropshipping is a great business model for a first-time ecommerce entrepreneur or people who want to test categories of products on their audience. Ecommerce entrepreneurs have even been known to run their ecommerce stores while studying, or working full-time.
Let no one tell you that email marketing is dead. An email list is crucial for every affiliate marketer. You can start building up your email list with a lead magnet (like the information products mentioned previously) or even just by encouraging your audience to sign up for your updates. You can then push your content to this audience via email and also direct them to your affiliate offers. Don't be sleazy about the sales, but if you build up enough trust with your email audience; when the time comes, they will not mind purchasing a product from you.
Watch them. How are other content creators in your niche utilizing advertising? What types of ads do they use? What are they promoting? What do they talk about repeatedly (if you keep seeing the same affiliate product show up again and again, there’s a good chance they’re making good money from it)? If you see a product or service they talk about that jogs your memory and you can ethically promote it too, find affiliate information by the methods described above.
