Getting businesses to advertise on your podcast, either at the beginning or end, or both, is a great way to create a revenue through podcasts. Most businesses won’t be keen to advertise on your podcast until you can prove a large number of listeners. Therefore, it is unlikely you will be able to start out from the get-go with sponsors. But once you accumulate regular listeners, or a high number of downloads from iTunes, you can start to sell advertising space on your podcasts.
There are loads of resources for making money online as an affiliate. You could source products from ClickBank, Commission Junction, Rakuten Marketing, Share-a-Sale, Impact Radius and many others. Plus, many of the larger companies have their own affiliate programs as well. Do your due diligence and find the right company with a relevant product or service to your audience that you can sell as an affiliate.
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
