So I found a product that i want to promote, and i set up a blog thru wordpress the free version for now. I'm adding tags to it, related to my niche, and also have sharing links on it, that links to tumblr, I also am updating my tumblr to my niche, and have several people sharing that. I have a twitter set up that people can follow thru my wordpress and tumblr. I am going to go to the premium wordpress, but just new at blogging, and have been updating a couple times a day. I'm using keywords in my blogs related to my niche also. I'm in the process of setting up a site for my niche, thru weekly and i want to know if its a good idea to buy the premium version of weekly to run my site on? The next thing I'm going to do is check out some blogs related to my niche and back link back to my wordpress..Is this a good idea?
