I basically add my Hub URL's to my pages. I usually tweet the URL to Twitter. I also find groups on Facebook that are relevant to my Hub articles and post them there. For example, I wrote and article about how to save money. So I found a Facebook group about saving money with about 1500 members of that group, and my article ended up getting a lot of views. Remember to first join the group and make sure posting your article will not be against any group rules. I have recently learned that with writing these articles, utilizing affiliate marketing skills helps.
