It's the same with affiliate marketing on Twitter. Sometimes, to get the long-term interest from users, and to convert those users into people who want to sign up for your affiliate programs, you've got to build up a working relationship based on trust and understanding. Twitter can be a great sales tool, but over a period of months, it can convince initially-skeptical people that you know exactly what you're talking about, and can be trusted with others' time.
Edit the Youtube video you want to add affiliate link(s) to. Click the Annotations tab and “Add Annotation.” Fill out the required info including the time you want that annotation to appear (obviously it should be when you recommend the affiliate product). Near the bottom, add your cloaked affiliate link. Apply changes, then watch the video and test your link.
Typically, the biggest mistake that most companies make is that when they connect, follow, or get followers, the relationship ends there. Just because you have followers or you follow others does not mean that you do not need to put in the work to develop a relationship. The fact is that you must be able to build a community that will maintain a good structure and will ensure the full potential for your business to succeed. Strong connections are often the result of your engagement with the community, so you need to participate and engage with your network. Otherwise, the people you are connected to will see you have no value and they will pay attention to other networks that are beneficial and offer them value.
