Recently joined an affiliate marketing program and most of the tools they give you are free. They say you can purchase things to advance you business but it is not mandatory. I have a feel for things now and have noticed there are many tools that a person can get that will help with your success. For example, you can get a nifty device that finds "golden" keywords in seconds. It claims it saves you time. And there are many more. I was wondering since there are so many choices can anyone give me advice on what I should invest in first? What have you seen the most success with that you have purchased? I have a website, blog, and lens. I write articles on a daily basis and have a handful in circulation. Any suggestions, thought, ideas?
