One mistake that pushes marketers into the "abyss of despair" is plotting out too many articles ahead of time. Don't do that to yourself. Remember, we're only human, and we can only work on one thing at a time. Start with article one, finish it, then move to article two. Don't take on too much at once because that's how you become overwhelmed.
Also, they provide a few banner ads images and custom links to track your affiliate sales. Frequently check the sales and clicks to increase sales. This is how generally you have to start affiliate marketing.

Apart from the costs associated with buying a domain and hosting it, there is no other cost involved except for maybe a tool or two (such as benchmarking tools to test product performance, and the like) which would still not put a dent in your wallet. You can write the articles by yourself; if you think writing is not something up your alley, you can outsource the content to freelance writers.
The only way they can do that according to Geiss, however, is if the team at your affiliate program management partner knows your product as well as you do. If they don’t understand your product, they cannot find the right audience for it.
