Well, this is a very broad question, because there are so many ways to do this.
It really takes time to know how to do this. Normally, if it’s a high converting offer your promoting to your list or blog (or however you’re promoting an offer) you shouldn’t have any issues (to a certain degree). So, I recommend only promoting products that convert well.
Having said that, your list, followers, or readers need to be interested in what you have to offer and the most important thing is to be related to why they are joined your list, started follower you, etc.
I hope this helps.
