In that regard, I highly recommend you build your own email list. By building an email subscriber list using a service like AWeber, you’re essentially creating a list of people that trust you and want to hear about your affiliate products' recommendations. Check out my free course on how to build your subscriber email list if you want to learn more about it.
When I purchase an existing online business, I look for cash flow over the past year and where the money comes from. I want the sources to be more passive so that it does not take a lot of my time. Also, typically I will make an offer that is 18 – 24 months of profit so that I know that I will get my money back within the next two years. I hope that helps!
Affiliate programs are the current hot thing in monetising websites. The basics are that retailers like Amazon will pay you a percentage if you send someone to their website to buy something. The percentage ranges from around 3% with sites like Amazon all the way up to 60% or even higher for information products sold by other people looking to make passive income.
When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
