Okay. I have an active blog that posts several times per day in the coupon market. I made a post about a shopping app about 2 weeks ago and the post has gotten about 200 hits. I have gotten several sign ups. I want to try and get more. So I have two questions. Would a low budget social signals service get me more traffic? (Its a Blogger blog) How often should I rewrite this post? I add content that is relative to the app fairly often, but most of my sign ups come from this source.
