Hey guys. I want to know if it matters where content is added? For example my domain is www. domain .com My blog where I have syndicated auto blog posts is located at http://www.blog. domain .com 1. Is having a blog that pulls from rss feeds a waste of my time? 2. If I am adding content to blog. domain.com, will that help my rankings for my main site www. domain .com? 3. If I were to buy a "service" here would I give the blog.domain . Com as the link to push or my main domain url?
