When done properly, writing your own personal recommendations will increase your commissions as well as sign-ups you get when promoting two-tier affiliate programs.
To help you get started, I've supplied following tips that will make your recommendations work for you:
1. Establish trust between you and your visitors.
Gaining trust of your visitors is key to increasing your commissions by writing personal recommendations.
Your visitors must get to know you and feel that you have their best interests at heart.
2. Publish an ezine or write your own e-mail courses that you provide to your visitors.
Both of these marketing techniques will allow your visitors to get to know you while also showing your visitors that your opinion can be trusted -- that you know what you're talking about.
In addition, make your site a resource to your visitors. Supply lots of information to your visitors such as your own articles, ebooks, or tutorials that relate to affiliate programs you want to promote.
3. When posting your articles on your site, have a recommended further reading section after your articles that links to affiliate programs that offer products related to what you talk about in your articles.
4. Recommend only products that you personally use or have first hand knowledge that they work.
